Yeast and Fermentation / Frozen 2112 Slurry
« on: April 20, 2012, 05:47:20 AM »
The strangest thing happened yesterday.  I took out my 2112 slurry to decant and wash on Wednesday.  Poured the water out from the top, filled with sterile water at the same temp of 36F and replaced in the fridge to let it settle out.  After this rinse I was going to pour the yeast off the trub and save for my next Steam Beer.

When I went to check to see if it had fallen out and was ready for transfer, I found it frozen!  The other containers in my fridge were fine, but this one had ice crystals throughout.  Any thoughts on what happened and how I can prevent this in the future?  And do you think I can defrost it and still reuse the yeast?  I swirled it up pretty good but there is still some ice in there.

Another thought would be in handling.  It's easy to grab a flask by the neck with an over mitt.  You'll probably need two hands with a beaker.  Could be awkward after boiling.

10-15 minutes at 144 can get a fair amount of conversion done.  However the rest at 154 should balance it out IMO.  Did you hit your target OG?  I don't think you should have rested shorter at 154 as you want to convert the same amount of dextrins as if you started there.  Not sure if the aggressive fermentation is due to the additional rest at 144 or the monster slurry pitch.  If it was fresh slurry, that could be it.

Others?

I don't see why it would make a difference what you use so long as you can cover the top and have it work on your stir plate.  I used a gallon jug and a gallon plastic pail before.

I'll gladly volunteer and offer up a bottle of my BoPils with the protein rest, hochkurz mash and single decoction to the participants.

1311
excellent everyone! Let me know how things turn out.

Dave thats a long protein rest!

I like mixing it up.  Took the recipe out of 'Designing Great Beers'.  I know malts have become more modified in the past 10 years, but I figured "what the heck".

Jason,

I did a 20 minute protein rest at 130 for the Kolsch.  Then 150 for 90 minutes.

For my BoPils, I did a 30 minute protein rest at 128, followed by infusion to 146 for 45 minutes, followed by a 15 minute boiled decoction to 158 for what ended up being 90 minutes because I was making another beer (gluten free for buddy) that tied up my kettle.  Mashed out at 170.  Bubbling along happily in my chest freezer at 52F.  Will post results.

So far I've made a BoPils and a Kolsch with it.  This weekend is my Munich Helles.  Do you plan on incorporating a protein rest or no?

Yeast and Fermentation / Re: Plastic Bucket for Lager Primary

That's the marketing anyway. Without details on the composition of the plastic, or controlled testing, who knows?

True, true.  They do have a lot of information however on their website with tech specs, chemical studies,  etc...  It's worth a look as they are a lot easier to handle/clean than glass.  No, I'm not a rep, just a home brewer who found a piece of equipment I like and recommend.

I've had very good success with mine.  I'd buy another over glass.  From their website:

Don't think of BetterBottle carboys as plastic – think of them as better than glass, because they are made from a special, scientifically tested, polyethylene terephthalate copolymer (PET), which does not have the disadvantages of other plastics.

BetterBottle® fermentation carboys are: are: 1) Designed to be strong, scuff resistant, easy to handle, and essentially unbreakable, 2) Pure – Taste- and odor-free, BPA-free, DEHP-free, and plasticizer-free, 3) Virtually impermeable to oxygen, 4) Clear and colorless, 5) Incredibly light weight, and 6) Extraordinarily easy to wash and sanitize (no brushes necessary). BetterBottle carboys are not at all like other plastic carboys. The special PET, used to make BetterBottle carboys, is non-absorbing, non-porous, and non-wetting (hydrophobic), so it will not carry over flavors from one batch of wine or beer to the next and it is easier to clean and sanitize than glass or other plastics.

Thanks all.  RDWHAHB and the plastic primary it is for my Munich Helles this weekend.

I plan to buy another Better Bottle or two soon, but need to space out my equipment purchases since my wife was kind enough to let me add another appliance to our garage.  I now have the chest freezer for my lager fermentation vessel, the upright freezer for storing food and an extra fridge where I store my lagers on the bottom and about 8# of leaf hops in the top freezer...... ;D

Brew on!

+1.  I think you are just inviting problems with secondary.....

Yeast and Fermentation / Plastic Bucket for Lager Primary
« on: April 17, 2012, 01:56:13 PM »
So, I bought an upright freezer on Craigslist for $100 and now have access to our chest freezer as my lager fermentation vessel.  Yes, it's lager brewing season as I can fit 4 carboys at once!

I have two lagers in there now in carboys, and want to make a third this weekend, but only have plastic buckets left for primary.  I know plastic was previously frowned upon for lagers.  But today, with pitching big starters and racking to keg for lagering after 3 weeks, do I really need to worry or should I just brew away and RDWHAHB?

On electric.  My LHBS owner promised me he has used his Bomex flask for years on electric with no problems.  I've made a dozen+ starters so far with no problems.  I have to admit, I was pretty tentative for the first one though......
