Yeast and Fermentation / Re: How low can you go?
« on: August 29, 2013, 09:05:04 AM »
Add some Brett.

+1 I think that without some very specialized yeast there will always be some longer chain sugars that will not ferment out. By the way are you talking about 100% Apparent Attenuation? ie. a finished gravity of 1.000? I've done that with the belle saison but I added some honey.

100% true attenuation would land you below 1. How much below would depend on the worts starting gravity

Is it really necessary to passify stainless steel?

it can get pretty rowdy

That will probably work but I gotta ask, what's there to deal with with BIAB. you've got to clean out your mash tun as well right?

If I were you I would go BIAB get a nice heavy duty colander that will rest on top of your boil kettle nicely and you can just lift the bag out and put it in the colander to drain while you start the boil. ideal for you situation I would think.

my guess is that the OG is a typo. maybe supposed to be 1.057?

Yeast and Fermentation / Re: dry yeast question

[...] Reusing dry yeast is somewhat trickier, I tend to pitch almost a third of a yeast cake for ales and almost half a yeast cake for lagers (harvesting the yeast cake at about up to a month from original pitch date).  [...]

what makes you say that reusing dry yeast is any different than reusing 'wet' yeast? by the time you are reusing I would think that the population is mostly new and those cells that have survived from the original population have used up any reserves given them during the drying process so there should be zero difference at that point.

So when did Morebeer open a warehouse in Pittsburgh? This is great news! I love their free shipping for $60 orders, but could never order yeast from California. Does anybody know if it's just a shipping warehouse or is it a store as well?

isn't your yeast coming from California anyway? or Oregon?

** actually lallemand is all over the place**

You don't need to pitch extra S-05 because you didn't rehydrate.  I go by my OG - if I get ~ 1.065 or higher I"ll  use maybe an extra 1/2 packet, because of the gravity not because of sprinkling it dry.

Awesome!  Now this answer takes me here......

What information is available that says viability is less/more/same when dry yeast-ing?  The info I have run across indicates that there is loss of as much as half the viable cells doing this. I think I read this in the "Yeast" book.  There also seems to be a difference in yeast cell count from the manufacturers and what is out there in the pitch rate calculators.

Use good sanitation and there's nothing wrong with rehydrating if you want.  I just haven't found an advantage to doing so - no loss of attenuation, no stuck fermentations ever by sprinkling on top. It's a highly attenuative, voracious eater, dry or rehydrated. One less thing to sanitize, and therefore, one less sanitation risk. I think the warnings are overblown, as someone who's brewed for a long time.

That's all good HoosierBrew!  I wasn't trying to aggravate!  Advice from seasoned brewers is very valuable.  I don't mind going through the sanitation process.  Using it dry is way easier though!  I was just looking for the "definitive" answer on pitch rate.  I think that is always what is behind the "use it dry or re-hydrate question" (that shows up often).  With everything in brewing being pretty scientific the specs around dry yeast are pretty loose......

Did you read the link to Sean Terrill's experiments?

For anyone who hasn't seen it yet, this is interesting:

some good info on exactly the effect of water v wort and dry yeast. if you are going after accurate cell count estimates this is the info you need (well actually for accuracy you need the cytometer etc.)

I usually rehydrate because that's what the manufacturer says to do, and for me it's easier to pour into my carboy. 

I have normally rehydrated dry yeast simply because I didn't have a good way to get the yeast into the carboy through the neck.  To be honest, I didn't try sprinkling down the hole because I imagined it would either stick to the neck or stick to the sanitized funnel. 

Does anyone has a nice trick to get the powedered yeast into the carboy or am I way overthinking this point?

the best trick I have found is to sprinkle the dry yeast on about a cup of warm pre-boiled water and wait till it... oh... nevermind.

If you have been rehydrating for that reason you should go ahead and keep doing it. or get some buckets.

People say there is no reason to rehydrate, if this is true why does the Safale website have these instructions?

(Rehydration Instructions
Sprinkle the yeast in minimum 10 times its weight of sterile water or wort at 27°C ± 3°C (80°F ± 6°F). Leave to rest 15 to 30 minutes.
Gently stir for 30 minutes, and pitch the resultant cream into the fermentation vessel.
Alternatively, pitch the yeast directly in the fermentation vessel providing the temperature of the wort is above 20°C (68°F). Progressively sprinkle
the dry yeast into the wort ensuring the yeast covers all the surface of wort available in order to avoid clumps. Leave for 30 minutes, then mix the
wort using aeration or by wort addition.)

I rehydrate per the instructions and have never had a problem and I dont have to spend the extra for more packs, (32 gallon ferment at a time), I rehydrate (7) packs instead of pitching 11-12 packs dry.

Is this a trick question? The instructions you posted not only suggest that you can use wort instead of water for rehydration but they also suggest that you can rehydrate directly in the fermenter.

also, have you considered trying to get professional pitch packages? it would probably save you money at that scale. Or reusing/propogating.

Commercial Beer Reviews / Re: Old Schoolhouse Brewery, Winthrop WA

I've had their beers a number of times at festivals and in bottles.  One of these days I'll get up there.

I believe Evan Ruud (old assistant brewer, son of owner, brother of head brewer) just went down to Durango Brewing where seanterrill used to work.

did he really name his son after an outboard motor?

Yeast and Fermentation / Re: First RIS - not quite done
« on: August 23, 2013, 12:50:49 PM »
are you measuring with a hydrometer or refractometer?

beer smith has a place to adjust the utilization %. it mentions that for larger system it should be greater than 100%.

overall though I go +1 on upping the early hops to get your IBUs

do you have any software? beersmith should be able to calculate those additions for you pretty well.

There are also on line calculators that will get you close but for 20$ I would grab a copy of beersmith.

Just out of curiosity why two coolers? I have the 72 qt with a SS braid and that works as a mash and lauter tun. (You could sell one and get beersmith!)

Start low and if you want more you can add more to the fermenter.

I don't know. adding fresh ginger to the fermenter might well result in biological activity that you did not intend. Lots of critters living on/in ginger.

I buy on, but in? I added a pound of peeled ginger to a fermenter once and didn't see new biological activity. Took a year for the ginger to mellow out though.

well there you go. I guess if your careful peeling and don't contaminate the peeled ginger too much it might be fine.
