3 weeks ago I made a St. Chuck's Porter using WLP-028 (Scottish Ale, the Edinburgh strain). I will be racking the beer to secondary this evening and plan to harvest the yeast for a Scottish Export 80/ ale.

Since it will be a week before I need the yeast, how should I handle the yeast. I see two possible options:

- Go ahead and store all the yeast in canning jars under pre-boiled distilled water in the refrigerator (my typical method for long term storage), and then make up a starter late next week from one of the jars.

- Or, put a pint of the yeast cake directly into a 1 gal. glass container, and top off with starter wort (1.040 SG) and let this go until I need it next week.

Obviously the easiest thing to do is simply make the starter up now, any downside to this approach?

TIA,
-Vince

Hi,

Why not do both???

I often take slurry and split it up. That way you can use the yeast a couple more times.

It seems to me there would be plenty of yeast even in just one jar. I have stored yeast cake in a sanitized pint jar in refrigerator for a week or so, let it warm up to fermentation temp. and then just pitch that into new wort with no starter. It takes off in a few hours.
You don't even need to cover with distilled water for short-term storage.

Pre-boiled distilled water seems like a lot of work. That's why God made PBR.

"...pre-boiled distilled water..."

I was wondering about that the other day. Since distilled water is made by boiling it off and then condensing the vapor, isn't it a little silly to boil it again, especially if the container is new (sealed)?

Hey Now,

"let it warm up to fermentation temp."

Yes... Be careful opening that jar as sometimes you may just get a yeast bath. A few times I have had some very active slurry in there.

"Pre-boiled distilled water seems like a lot of work. That's why God made PBR."

I thought that PBR was only for drinking and boiling BRATS in Chumley.

I would do (and have done) what Miker suggests. It's the easiest solution and will work just fine.

Bud Light make a nice sanitary rinse and yeast wash. Be carefull to wash your hands afterwards, dont want to acidentally get any near your mouth.

There is some disagreement about this, but I am in the camp that prefers distilled water for long term (more than a couple of months) yeast storage. The reason for boiling the water is that unlike tap water it has no added chlorine to prevent contamination by airborne microorganisms.

Covering the yeast with beer (yes, any beer, including PBR), however, is more than sufficient for shorter term storage.

If you are going to use the yeast within a week, you could make a starter now. This isn't really necessary if you are saving the entire yeast cake. In any case, if the yeast is a week old, it would be best to feed it a quart or so of starter wort on the morning of your brew day.

Hey Now,

I gotta go with Bill on this one... For term storage distilled water is the best.

I have used beer from time to time also though.

The OP wants to hold the yeast for a week.

On a few occasions I've added some beer to the primary fermenter after racking, swirled it around and poured the slurry into a sanitized growler, which I capped and stored in the fridge until using it to brew a week or two later.

PBR is the wonder beer, Skot...in addition to the three uses we've identified, another is topping off oak casks full of lambic to account for evaporation losses...if NASA could freeze dry PBR, I am sure that astronauts would have it.

I agree with Scott. Split the yeast cake into more than one clean/sanitized mason jar. Store one (or more) in the refrigerator, and leave one at room temp (65-68). A couple of days prior feed it into a gallon starter if you want to, or pitch it right into your wort.

After a bad experience with a canning jar and some WY1214 that I still can't get off the ceiling, I now store harvested yeast in beer bottles with an airlock. After a couple of weeks I replace the airlock with a sealed cap.

You might be surprised at the amount of pressure that can build up if you tightly cap freshly harvested yeast. I recently racked a bo-pils to the secondary, and harvested some yeast to a growler with an airlock on it. As I ramp down the temperature to lagering, there is more activity in the airlock of the 20 oz growler of slurry than there is on the airlock for the 6 gallons of beer in the carboy (yes, the carboy is properly sealed).

I NEVER close Mason jars tightly when yeast are in them. Leave the lid slightly loose.

That's why you refrigerate. I usually put jar lids on loose until well cooled then tighten up (hmmm... that reminds me that I didn't tighten up those jar lids from the WY1007 I harvested a couple of days ago from that Alt racking)

Also, when warming yeast, I put jar into a large sanitized measuring cup so I don't lose any yeast that overflows the jar.
