Judging date: December 5, 2009 starting at 9AM Judging location: Oldsmar Taphouse, 300 State Street East #107, Oldsmar, FL 34677 Staying overnight? You ARE judging strong Belgians and other Imperial beer! Try Holiday Inn Express, 3990 Tampa Road, Olsdmar, FL 34677, online rate currently about $64. Dunedin Brewers Guild is very happy to announce that Oldsmar Taphouse will be hosting Walk The Line On Barleywine again this year. In addition, OTH will be hosting the American Homebrewers Association Club-only-Competition for Strong Belgian Ales (BJCP style 18). These are both competitions with big beers in them - and I'll need some help to judge them all! We will be judging all day, starting at 9AM, and judging for both competitions. Both competitions are AHA sanctioned for BJCP judging points, and the BJCP 2008 judging guidelines will be followed. For more information, or if you have not yet entered your beers, check out the Dunedin Brewers Guild website at www.DunedinBrewersGuild.com. IMPORTANT - please email me back if you plan to come, so that I can schedule flights. Judges who RSVP will receive priority.

Date: Mon, 9 Nov 2009 08:10:41 -0500 From: Fred L Johnson <FLJohnson52 at nc.rr.com> Subject: Re: false bottom specs Ralph asks how high off of the bottom a false bottom should sit. I believe one should make that height as small as possible. The space under the false bottom is essentially a mixing compartment which reduces the effectiveness of the fly sparge. Ideally, one would want the concentrated wort dripping out of the grain to directly the outlet with a tiny tube at each hole in the false bottom. By have a space (compartment) below the false bottom, the concentrated wort enters this pool and is gradually, continually diluted with less concentrated wort entering it. This mixture is what leaves the the outlet, not the concentrated wort. The larger the volume of this compartment, the more dilution that will be required to get the wort out. For the sake of illustrating this, imagine how inefficient lautering would be if one had half of the total mash liquor volume below the false bottom. Although the sugar may have been very effectively leached out from the grain bed above the false bottom, the leached sugar will remain within the compartment below the false bottom for much longer time because it doesn't immediately leave the lauter tun. This is why false bottom designs are not necessarily more efficient than the Bazooka screen type of design. My old perforated bucket in a bucket lauter tun design got about 70% efficiency by fly sparging with 2.6 quarts per pound of grain with beers using 10-12 pounds of grain. That lauter tun had about a 0.6 gallons of wort below the false bottom. When I switched to a single, one inch Bazooka screen, my efficiency immediately went up to about 83% using the same ratio of sparge water volume to grist weight and every thing else being the same. I contend that the difference in efficiency was NOT in how efficiently I was leaching sugars from the grains. In fact, according to Palmer, I may have been under leaching sugars from parts of the bed lateral to the Bazooka screen. The efficiency difference was in how much wort enters the Bazooka tube compartment (about 3.4 oz in an 8" screen/spigot length), i.e., compared to the 0.6 gallons that was below my false bottom.

Date: Mon, 09 Nov 2009 10:58:13 -0500 From: "John W. Zeller" <jwzell at current.net> Subject: False Bottom Specs Ralph Link requested specifications for a false bottom he is building. Specifically, how much clearance should there be below the FB. IMO, the dead space isn't critical at all. The best answer would be to position it as close to the bottom as possible. Obviously, it should be higher than the outlet port, but it's also good to have it above a sight glass port if one is used. This keeps grain and particulates from entering the sight glass and positioned this way the sight glass can be used as to eyeball the suction if you are pumping directly out of the MT. The sight glass would also be a vent to the atmosphere which can help avoid excessive pump suction that can lead to a stuck sparge. The reason I say the dead space is not critical is that any wort remaining there at the end of the sparge will typically be of very low gravity and not worth recovering. I guess the exception might be when batch sparging where the runnings may have a higher sugar content. In that case I suppose you could tilt the kettle to drain the dead space if need be. I don't batch sparge, so YMMV on that. The 24" diameter is a pretty big span, so it might be a good idea to provide some supports in the center area to keep it from collapsing. Even low levels of suction applied can put a big load on the FB. -john z cincinnati Return to table of contents

In general, I'd say the closer the better, as long as it clears the drainage valve. The liquid under the false bottom is not participating in the starch conversion and only serves to dilute the enzymes. I brew with a 15.5 gallon system and there is 2.5 gallons under the fb in order to clear the valve. This has never caused any trouble, but I can't help but think that less would be better.
