After swirling the wort really well, let it sit covered for 20-30 minutes while you do cleanup. Then syphon it directly into the primary fermenter. The wort mess you leave behind can be left to sit overnight in a cool place, like the patio. The next morning decant the wort into a 1 quart jar and put it in the refridgerator. Next time you brew, you've already got 32 oz of starter wort in the jar. Just reboil for a few minutes, pitch. No need to waste the left over wort. Charley Return to table of contents

I'm a fan of Belgian and wheat beers, and one characteristic these brews share is a big head. I've been unable to replicate the extreme carbonation that these types of bottle-conditioned brews achieve, even by adding somewhat excessive amount of corn sugar for priming (within safety limits). I'm wondering if anyone has any secrets for getting that "I'm so happy to see you" foamy head. Possibilities that I could see for experimentation would be kreusening, mash temp schedules, mash schedules in combination with kreusening, aging time and temperature, yeast strain, and probably about a dozen more I won't bother with in the interest of space. Anyone figured out the secret of big head? SM Return to table of contents

I have brewed a number of coffee stouts that have come out excellent. I use between 1-2 cups of course ground coffee, preferably and high quality espresso roast, steeped in the wort for 20 minutes after the boil. If you decide to use 2 cups, you'll get a fairly strong but not overpowering coffee taste (in an imperial-stout kind of beer). It will mellow with time. At first, the coffee aroma might seem to strong, but most of it gets blown off with the fermentation. So, thats my late late input.

The thickest part of the mash is almost all grain. You want to take very little liquid. The enzymes are dissolved in the liquid. The decoction process denatures (destroys the effectiveness of) the enzymes. When you add the decocted portion back in, you want the enzymes to continue the conversion process at the higher temperature. > I have always been skittish to try decoction mashing.

Date: Wed, 8 Jan 1997 00:36:27 -0500 From: nerenner at umich.edu (Jeff Renner) Subject: Canadian ale recipe In Homebrew Digest V2 #21, Derrick Yacavone <dyacavone at sprintmail.com> asked > >My Spousal unit requested(i am still in shock), that I brew a Molsen(no >ice). Can anyone that may have a recipie(grain or extract) pass it my >way via e-mail? TIA dyacavone at sprintmail.com I just brewed two Canadian ales this past week, both a little more flavorful than Molsons - a bit more hops and no flavor-minimizing brewing techniques, so maybe this'll make both of you happy. They are probably typical of older brews (pre 1950's). Fortunately, Molson ale yeast is readily available as YeastLab A07 Canadian ale yeast. It gives that typical Canadian grapey fruitiness. I've found that if you want to keep this character in rein, it's best to keep fermentation no higher than the mid 60's. With my first batch, it went to 71, making the grapiness a little strong, although it'll mellow out. For a Canadian ale (or lager, for that matter), you need corn - 20-30%. Don't shudder - it's a Good Thing (tm) for that style. Six-row barley is appropriate, but two-row domestic would be acceptable. (See the new issue of Brewing Techniques for a complete discussion of 6-row vs. 2-row). Michael Jackson says (New World Guide to Beer, p. 198), "In general, Canadian brewers often use six-row barley, and this can impart a slightly husky taste to the beer. They also use a lot of corn, which can create a creamy sweetness. The balance of these two elements could be taken to represent a "Canadian character." I'd stay away from British malt because there might not be enough enzymes to convert the corn. In my first batch, I used flaked corn, which requires no cooking, right in the mash; in my second I used yellow degermed corn meal, which I boiled with some malt. Commercial brewers would use brewer's grits, which is just big grained corn meal. I also used some Munich malt to give just a little more color and maltiness, which is typical of Canadian beers as compared to US ones, and torrefied wheat for head retention. Some additional color and maltiness came from the decotion. Cluster hops for bittering is also typical, although any neutral hop is appropriate. I used Bullion (which comes from a cross with a wild Canadian hop) because I didn't have whole Cluster; I used Cluster pellets for the first batch, but pellets don't filter out the trub. European or English finishing hops would be appropriate. The typical Canadian beer is 5% alc v/v, or 4% w/v, so OG 1.050 would be about right. Here's my recipe for the second batch: - -=-=-=-=- Mackenzie River Canadian Ale (*7 gallons* (final volume) OG 1.051, FG 1.013): 8 lbs Schreier 2-row malt 1 lb. DWC Belgian Munich malt 6 oz. torrefied wheat 3-1/2 lbs. yellow, degermed cornmeal (27% of all grain) Water - Temporary hard well water boiled, decanted, +2 tsp. gypsum/15 gal. Cereal cooker mash - 2 lbs. 6-row plus 3-1/2 lbs. corn meal, mashed in to 120F (loose mash), raised to 152F, held 15 minutes, then raised to boiling, boiled 40 minutes, then added to main mash. Main mash - balance of ingredients, mash in to 122F, 1 hour protein rest (a little long, should have started later so only 30 min. protein rest). Then added cereal mash, which boosted it to between 130F - 136F, heated and stirred to 140F, rested 10 minutes, then pulled thickest 40% (decotion), heated to boil over 10 minutes, boiled 30 minutes, returned decotion to main mash, which raised it to between 150F - 155F, stirred and heated to 158, held 30 minutes, then mashed off to 170F. Lautered, collected 9 gallons, boiled 75 minutes to 7-1/2 gallons. Hops: 0.6 oz. Styrian Goldings plugs (7.5%) first wort hopping (then boiled 75 minutes) 1.4 oz. Bullion (whole) (5.2%) 75 minutes 0.6 oz. Styrian Goldings plugs 15 minutes 0.8 oz. EK Goldings pellets 5.2% at knockout, plus 10 min. steep before chilling This should have given about 31 IBU per Glen Tinseth's online bitterness calculator, but I'd judge it to be mid-20's IBU. Perhaps this is the effect of FWH, which gives a more mellow bitterness. At any rate, it is nicely balanced, with enough bitterness to be distinctively unwimpy, but not at all aggressive. Immersion chilled with recirculation to 65F, pitched 7 fl. oz. thick yeast paste (YeastLab A07 Canadian Ale Yeast) into boiler with hops on false bottom and continued recirculating to filter trub onto hops bed, splashing to aerate 1 hour, then pumped to fermenter. Open fermented 66F-68F 3 days, then racked to secondary. At racking, the restrained maltiness was evident, with some corn sweetness and graininess, with plenty of grapefruity hops flavor interplaying with the fruitiness of the yeast. Very pale gold, but darker than US beers. Nice, clean lingering light bitterness. This will be a good one when it's bottled. I can't wait. - -=-=-=-=- Jeff Renner in Ann Arbor, Michigan c/o nerenner at umich.edu Return to table of contents

In the past I think I've read a few similar complaints. However, I use Irish Moss for every batch and I actually throttle the flow from the spigot to keep it from being too fast. Hence, it's hard for me to imagine how this is happening. Remember that it's important not to stir after the boil if you are doing this. If you're using an immersion chiller, just suspend it at the top of the wort as I described so you can chill without stirring. I think the person who mentioned that the trub settles on top of the hop bed has it right, and this makes for very effective filtering without clogging. - -- Alex Santic - alex at salley.com Silicon Alley Connections, LLC 527 Third Avenue #419 - NYC 10016 - 212-213-2666 - Fax 212-447-9107 http://www.salley.com Return to table of contents

Hey George - What you have run into is typical with most SS Welding. What happened is that the oxide layer that prohibits stainless from rusting got wiped out by the welding process, and you need to give it some time to 'recondition' itself and reform the layer. Lightly sand the areas down to clean bare metal again, and let it sit for several days (maybe a week or so if you have the patience) and then it should be ok. This is assuming that it is stainless, and the welder did use SS welding rod with a decent MIG/TIG torch. Good luck!

Date: Wed, 8 Jan 1997 08:41:42 cst From: Bill Giffin <bill-giffin at juno.com> Subject: Husks, good or bad? Good morning all, A continuing thread over the past couple of years and something that you are warned about in all grain brewing is the husk portion of the malt. The husks have been blamed as being the major source of tannins in beer, yet when beer is brewed with the husks being sieved off, the tannin is about 91% of the tannin found in beer that is brewed with husks. Where is all this tannin coming from? At least some of it is coming from the hops. The husk fraction of malt has a major effect on the flavors and stability of the derived beers. Malt grist freed from husk material by sieving makes bland and insipid beers, while grist enriched with "husk" produces astringent beers that readily become hazy. Husk material is rich in silica and you may want to limit the amount of silica in you beer. Low extraction rates for all grain brewing is taken as the norm. The answer is to add more malt to the mash tun to get the gravity. When you add more malt to the grist to achieve the same result you are also adding more husk material. More husk material equals more off flavors and beer that is not in balance. Lets take an extreme example. If you brew a beer with an original gravity of 1.050 and you use 10 pounds of grain to brew that beer, then you will have 36% more husk material then another brewer who can brew the same beer with 7.35 pounds of malt. I feel that this is a good reason to get your brewing efficiencies up to make better beer. The difference between brewing truly great beer and just drinkable beer isn't that much. Balance of all the ingredients is essential. The balance of the different malt fractions to each other. The balance of the hops both in flavor and bitterness to the malt. The balance of the yeast characters to both the malt and hops. Bill Giffin Richmond, Maine Return to table of contents

Date: Wed, 08 Jan 1997 09:12:29 -0600 From: Keith Busby <kbusby at ou.edu> Subject: Gott cooler and mash temps. I am about to invest in a 10 gal. Gott with false bottom or Easymasher (any preferences?). It is usually said that you should heat your mash water 10 degrees higher than initial mash temperature as the grain absorbs heat. Will this still be valid for a cooler? I'm presuming so since it will not be insulated until the lid is on. My real question concerns how to raise to mash-out temperature. With a grain bill of, say, 10lbs, and 1 qt mash water per lb at 155 degrees, how much boiling water would I need to raise the temperature to 168? As an alternative, Papazian somewhere suggests heating your sparge water to 180, adding a quarter of it to the mash (this would be about 1 1/4 gals) which would raise the mash to 168 approx. In the 10 minutes required for mash out, the remaining sparge water would be allowed to cool to 170. I would prefer not to remove and reheat the mash and return to the cooler. My instinct tells me to go for Papazian's suggestion as I fear pouring boiling water on top of the mash might upset the chemistry.

Date: Wed, 8 Jan 97 10:10:06 UT From: C&S Peterson <CNS_PETERSON at msn.com> Subject: Decoction Mashing Todd Wilson wrote: <begin quote> Steve Garrett's question on a single decoction mash got me to wondering...What exactly do they mean when they say "pull off 20% of the thickest part of the mash" and boil for however long. I have read CP, Miller, and the Brewing Wheat Beer book and I am still unsure. I am assuming that they mean to scoop out 20% of the mash, boil and add it back but where I get confused is are you pulling out just liquid or liquid and grains? I might be nuts but if you pull off liquid and grains what are the tannin risks? <end quote> Generally, I've had success with just pulling the "thick" part of the mash out of the tun with a hand-held kitchen strainer (the wire sceen kind that's been around for centuries...). This saves most of the enzymes in the liquid left in the tun and leaves me with a gloppy thick decoction mash. But I generally add boiling water to the decoction mash and maybe some heat to get it to mashing temps (158-162F), because this thins the decoction a bit so I don't get scorching problems during the decoction boil. I get the "thin" decoction by simply running out a few quarts of wort out of my lauder/tun and boiling for 15 minutes or so. This bit of heat (for a double or triple decoction, I believe), gets me from main mash temp to mash out (about 170F) and adds some good carmelizing to the finished wort. I tend to use this last method even with my infusion mashed beers to get to mash out. It saves me some volume in the mash/tun, and I get a little more color and carmel notes in the finished beer. Recently, I started my decoction beers the night before I brew. I separate the grist into 1/3 and 2/3 protions. The 1/3 mash portion will be used as the first decoction. I mash the first decoction protion in at about 125F using about 1Q/# of grist (which will make a fairly thick mash stand), and leave in a cool oven overnight. During the 5 or 6 hours I'm sleeping, the temp drops to just below 100F. This sets the decoction down through the protein and acid rests. Not traditional, but hey, its worked so far! On brew morning, I add heat and hot water to the decoction mash to bring it up to main mashing temps (158-162F). While its mashing I heat up main mash infusion water to 160F/# of gist and keep it warm on the stove. Once the decoction mash has completed starch conversion (usually 30-40 minutes), I bring it to a sustained boil. With the decoction boiling, I then add the 160F degree water to the main mash, bringing it up to 140F. When the decoction boil has completed (usually about 30 minutes), I combine the two mashes and adjust with hot/cold water to the desired mash temperature. The second decoction is the "thin" decoction to get to mash out. While this seems complicated, I find it is actually less hectic than a traditional decoction mash, since I'm able to heat up the main mash water separately. Also, it has the benefit of reducing the Ph in my mash naturally (although I find I still need some acid blend in the main mash and sparge). But most importantly, it avoids a lengthy main mash rest at 122F, which, IMHO I always found to be a PIA (I always seemed to run out of infusion water space in the lauder/tun) and I think led to reduced head retention and body in the final beer. So far the results with this method have been good, but it's still to early to tell. To avoid any tannin problems, you have to watch your Ph more than your temps. I like to see about a 5.0 Ph reading in the docoction kettle before I venture across the 170F level. Make sure you use GOOD Ph strips or a GOOD meter -- I lost 20 Gallons of brew to the "pheonol troll" last year using out dated and cheap Ph strips. The expensive ones (like $15 per 100, available through Brewers Resouce and elsewhere) is what I depend on. Great to be back on the HBD, Chas Peterson Return to table of contents
Date: Wed, 8 Jan 1997 10:53:15 EST From: Curt Speaker <speaker at safety-1.univsfty.psu.edu> Subject: which style? Hoppy New Year: I have a question for the homebrewing collective out there... I have a rasberry chocolate stout that I am considering entering into an upcoming competition. The cocoa flavor is very strong, with the rasberry flavor somewhat in the background. After sampling one last night and reviewing the style guidelines (1996), a can't decide which style to enter it into. Is cocoa considered a spice (as the guidelines say - " derived from plants, roots, leaves, etc.")? I don't think it would do too well in the fruit beer catagory since the rasberry flavor is rather subtle. The specialty beer catagory caught my eye, but that seems to be for beers that are made with unique ingredients (maple syrup, etc.) or a unique process (steinbeer, for example). Does anyone have any suggestions on which catagory would be most appropriate for a stout with a strong cocoa flavor and a subtle rasberry flavor? Herb and spice? Fruit? Specialty? Any advice will be considered, and greatly appreciated. BTW, the entry deadline is this Saturday, so if you do respond to me, please do it soon!

Date: Wed, 08 Jan 97 11:12:00 PST From: "Koucheravy, Edward R." <KOUCHERA at pentagon-paed.army.mil> Subject: Bottling Time (Ed Koucheravy) Dave Winfield writes: ">BTW the instructions indicate fermentation should last "3 to 7 days" and >bottle when FG is 1.005 - 1.010. ... "My understanding is that the end SG is not the issue but rather that the SG is the same for 2-3 days in a row. (record one then record another in 3 days, if they're the same then you should be ready to bottle." I used to do this, ala Papazian, but my experience is that taking successive Final Gravity (FG) readings is generally unneccessary. Mucking around in your fermenting beer invites infection. I have had good luck by observing fermentation (which is much easier in a carboy than a plastic fermenter). The krausen usually falls in 3-6 days and the CO2 production also falls off. I usually wait several days beyond, when the airlock is "dead", and then bottle. I take the FG for my records, but don't really worry about it as long as I get vigorous fermentation in the first few days. If I use a secondary fermenter, I always record an SG, but have found negligible fermentation after 7 to 10 days in the ales I brewed. FG's can be misleading. I once made an extract stout using 6 lbs. Of Laaglander DME. I had a typical active fermentation, but after a week the FG was 1.027, significantly higher than the target FG of 1.015. I was convinced I had a stuck fermentation. After 10 days of concern, warming my carboy, adding fresh yeast, etc. and no change in SG, I realized that 1.027 was the FG. I went ahead and bottled, concerned about glass grenades and needlessly worried. It was a good learning experience, I later found out from the HBD that Laaglander DME is notorious for a high level of unfermentable sugars (dextrins). BTW, the beer was good (although pretty heavy, even for a stout). Sorry about your difficulty in walking: "I will introduce myself as I have also been lurching...."

Date: Wed, 08 Jan 1997 11:35:35 -0500 From: Aeoleus <osiris at net-link.net> Subject: Fruit Question I have a couple of questions regarding fruits in beer: 1. Upon racking, is it kosher to return the carbouy to its original fluid level with something like Apple Cider or Cranberry Juice? I realize that such introduction of new sugars into the solution would cause more fermentation to occur, but if you waited for that to stop, what would be the result? Would you sit there for years racking, adding Cider, waiting for fermentation to quit, then deciding you need to rack again? 2. Is fruit a viable addition to a kit beer? Right now, "my second batch ever" is sitting in a secondary fermenter while I make absolutely sure that fermentation has quit (Making mead has put the fear of god in me about Glass Grenades). The Kit I used is a lager, and smells like it would overpower fruit additives. If it's okay to add fruit to kit beers, when do I add, and how much? What kind of kit allows the flavour of the fruit to come through? And about honey: Can I use honey instead of priming sugar before bottling? How much? Thanks for your input, this digest is amazing. - -- Brian Ream Kalamazoo Michigan - -- mailto:osiris at net-link.net http://www.net-link.net/~osiris - -- China - Free Your Future!

In response to George de Piro who inquired about the the Westchester Brewing Company, a new brewpub in White Plains, NY: I've been going to the WBC frequently. The beer is not bad. I enjoy the Hutchison Ale the best. The other's are fair. They just unveiled a Plum Wheat that is God awful! My advice is to go to the Lazy Boy Saloon directly across the street near the corner of Mammaroneck Ave & Post Road. They have 30+ on tap plus well over a hundred in bottles. What ever you what, they got. I know the owner, who also owns the cigar/homebrew store next door (White Plains Tobacconist). The Lazy Boy is by far the best beer bar outside of NYC as there is nothing like it except maybe Company B's in Rockland (so I hear--I've never been there) Stop by the WBC, but stay at Lazy Boy's! The food is good in both places. WBC charges a lot for their own brews, which is all they serve aside from mixed drinks. The ambiance is good too, but since they just opened a little over 2 months ago, their brews need improving since they are all quite bland (even the porter, IMHO). They best bet is the Lazy Boy directly across the street. I know people who drive 50+ miles just to get to the Lazy Boy, as there is no other like it north of NYC. It's that good! Enjoy!

Surely there must be some?" To which my response was "I don't know, and stop calling me Shirly." Anybody else got any information on what tannins are extracted during a decoction, and if any, what happens to them? Do they get reabsorbed by other grain husks? If tannins mask the taste of melanoidins which are supposedly extracted preferentially in the first runnings, it seems you would be defeating the purpose of no-sparge brewing if you also used decoction. Anyone?....anyone?.... - --> I have a nice starter going of yeast obtained from a sixer of Widmer Bros Hefeweizen. They claim it's a secret yeast strian given them by a German brewer. Supposedly, it stays pretty much in suspension. Anybody know what it is? I plan on using it this weekend to make my own version of fruited hefeweizen.

I have already read TNCJOH and would like to continue my education. So, basically what I'm asking is what are some good books? What are some good periodicals?

Assuming you know the OG of the first batch its easy. Lets say for instance that the first batch OG was 1.080 and FG 1.010 for an ABV of ~9.4%. You want to reduce that to no more than 8.0 which is a ~15% reduction. Simply reduce the total sugar contribution. This assumes that all sugars are equally fermentable, but what the heck we're not rocket scientists here (at least not me) and this should get you very close. Assume 30 points per pound per gallon for LME and 42 Points per pound per gallon for DME. 3 lbs DME = 126 points 6.6 lbs LME = 198 points For total of 324 points. Since the total points was 400 (80 - 10 plus raspberry contribution), you need to reduce overall 60 points. You get to make the call on which sugar source to reduce. My preference would be to reduce the DME to 1.5 lbs (easy to measure and store left overs). You could always leave it at 2 lbs (reduction of only 42 points) and take the rest out of the fruit to better balance it. For the second question, I would get a hop ibu calculator (there's one on the web at: http://realbeer.com/hops/IBU.html). Start with the original recipe and adjust it for the bitterness level desired. I know this isn't much help, but hops are so subjective. Good luck. I'm sure there's a hundred brewers out there reading this ready to tell us where I messed up, but it looks right to me. You just need a place to start from. Charley Return to table of contents

I don't know about flavour, but DeClerck says that hot and cold break remaining in the wort can interfere with the yeasts' uptake of nutrients (?) or sugars (? I don't recall which). He claims that healthier ferments can be achieved when you remove the trub. Also, either George Fix, Malting and Brewing Science, or DeClerck says that something like 75% of the haze- forming material can be removed from the wort by removing the break. Personlly, I have never made special efforts to remove break (my new kettle design was for other reasons) and have been happy with the resulting beer. *** > I have read about this practice on the HBD and have always wondered, > "Why do people do this?"

I could be wrong about this, are there any other opinions > out there? Not all the sugars in crystal malts are bound up in caramel. As for whether they crystal malts are high in limit dextrins, I don't know and it's on my list of things to investigate, but I'm pretty sure that there are some saccarifiable dextrins in crystal malts too. How much of them are limit dextrins and how much are subject to beta amylase breakdown is a good question. Anybody have this data? The bottom line, however, is "What do you want... dextrinous wort, fermentable wort, or something in-between. If you want dextrinous wort, then mash at the warm end (around 158F)... if you want fermentable, mash at the cool end (around 150F)... I too don't understand why somone would mash at the cool end of the range and then later add the crystal malt to bring up the dextrin content... If you regulate fermentability with the mash temperature, then it shouldn't matter when you add the crystal malt. *** Cliff writes: >2. 1214, 1762, 1388 and 3787 all produce fine Belgian Abbey style ales. >Dr. Michel Brown has pointed out to that esters are more predominant in >the lower numbers and reduce in the higher numbers. Just a datapoint: this last Saturday I used 3787 to make a Tripel (note spelling). The starter was fermented at about 65F. It REEKED of bananas! I therefore put the fermenters into the cold part of the crawlspace and they have been fermenting there happily at 50F (well below what Wyeast Labs recommends). *** Rob writes: >I got half way through capping them when I realized that about 20% of >the bottles were twistoff!

Everything I've >read mentions using non-twistoff bottles. Obviously Coors gets their >beer to carbonate OK in twistoffs. Two points: 1. There are special cappers that put the caps on twistoff bottles... they are different from our crimp-on cappers. 2. The main difference between twist-off and pry-off (that's what Zapata calls them) caps are that the metal is thinner on the twist-off caps. I've tasted both well-carbonated and totally flat homebrewed beer from twist-off bottles... I believe that it may be capper-dependent, but you run the risk of getting a certain percentage of flat beers if you use twist-off bottles. I've never used caps labeled "twist-off" nor can I remember running into them at homebrewing competitions, so I can't help there. *** Todd writes: >wondering...What exactly do they mean when they say "pull off >20% of the thickest part of the mash" and boil for however long. The "thinnest part" is just the liquid. The "thickest part" is mostly grain with just enough water to prevent scorching. >I might be nuts but if you pull off liquid and grains what are the tannin >risks? Darryl Richman first theorized (here on HBD, perhaps 1988 or 1989) that the pH of the mash may be what's limiting the tannin extraction in the decoctions. The topic has been brought up perhaps 10 times and pH has always been the answer with no opposition. So, again, I'll suggest that the pH is the reason and perhaps someone with other sources of information will confirm or deny. *** Marty writes: >Just an FYI to anyone thinking of using an EasyMasher for filtering the >wort after the boil: It doesn't work worth a damn if you use Irish Moss in >the boil.

And I suspect that it works fine for this >purpose if you don't use the moss. I used Irish Moss (1.5 tsp/6 gal boil) on that Tripel and a Bock this last Saturday and I have EasyMasher(tm)-like screens in my kettles. There were no problems when draining the kettles. Perhaps it's because I used whole hops loose in the boil? Do you think that might be what saved me, Marty (seriously)? *** Val writes: >is there any concern or disadvantage to soaking bottle lables off in a >solution of water and washing soda (sodium carbonate)? it seems to do the >trick in about 4 hours. i also figure the washing soda is helping to clean >them. sometimes there is a white film left on the bottles. is this cause >for concern? I would say, probably not, but early-on in my brewing career, I did this and was worried about the carbonate deposits... I found that a short soak in lemon juice and water (or lactic acid, or phosphoric acid, or acid blend) removes the white film. *** Jim writes: >I have one good suggestion, allow for a *very* long brewday when >using Weyermann malz!

The aforementioned Tripel and Bock were made from something like 75% Weyermann Pils and 25% DWC Pils and with my EasyMasher(tm)-like screens in the mash/laeuter tun, I got 12.75 gallons of wort in about 1.5 to 1.75 hours. I used a 30 min rest at 144F, followed by 1.5 hours at 153F and had to throttle the ball valve on the tun to keep the flow rate *down*. Just a datapoint. Al.
