no obvious signs yet.  I did put the space heater in last night to make sure the temp didn't drop below 63F (set to 64F +/- 1F).

Used BRY-97 about 3 or 4 times. always noticed a long lag on it, 24 hours or so. direct pitch or hydrated, with the wort aerated with 02.

24 hours is pretty normal for dry yeasts for me.

Yeah, and unless it goes a lot longer than that I don't worry.

[positiveContact]

so about 24-25 hours in and I think there is some real positive pressure going on.  not too bad at all if this is really the start.

[positiveContact]

that was probably the real start last night.  def fermenting this morning.

[positiveContact]

I've been letting the pressure build up the last couple of days.  a few days ago I accidentally set the pressure too high and built up about 20 PSI of pressure.  when I went to dry hop it foamed up like a bastard as I let out the pressure which created quite the mess.  I cleaned it up as best I could and got the hop pellets in and sealed it back up.  back to to about 25 PSI now and maybe still slowly rising.  I'll start venting if I get to 30 PSI.

 

the yeast performance seems okay in terms of lag.  fermentation is going on a little longer than some other yeasts I've used but still nothing too crazy.  Today is 1 week since brewday.  if the pressure doesn't build up much today I'll probably get a picnic tap assembly sanitized, pull a sample and check the gravity.

Why such a high pressure?

[positiveContact]

The 30 psi? At 70f that gets me to about the right carbonation level.

beer came out very nice as far as I can tell (needs to clear a little more before I can be sure what's going on).  yeast character seems pretty neutral/clean.

Why do you carb at 70dF?

I am pretty sure he is spunding at the end of fermentation so he can naturally carbonate the beer with the tail end of fermentation.

Yep.  Since I dislike 05 so much, this has become my go to dry yeast.

That is correct. Saving the world a little co2 at a time

I'll need to make more stuff with it but as of now I suspect that I prefer it to us-05 but probably not as strongly as you.

Interesting. Still seems high. I usually spund at 15 psi and then crash. Usually drops a couple PSI as the temp drops. Then I transfer to the brite and carb with 16-17 psi with the head pressure after transfer at about 15. I don’t have a Zahm so I’m not 100% sure where my volumes end up but it comes out about right. My brite doesn’t really get below 37 dF unfortunately, same with my fermenters but the beer pours right and doesn’t seem over or under carbed.

just a minute and I'll show you a pour straight out of the primary.  carbonation is just about perfect.

 

if you look at a carbonation chart at 38F you'd need about 910 PSI to get around 2.3-2.4 volumes.  To get 2.3 volumes at 70F you'd need over 30 PSI (off the chart on the table I have).

[positiveContact]

looks pretty good I think...

 

[Genesee Ted]

Can’t argue with that!

One of these days I hope to get a zahm and get everything a little more dialed in. I’ve looked at the chart for sure, but it seems that the beers come out under carbed if I go any lower.

yeah - I've sometimes overdone it at 30 PSI but not by a lot so it's easy to fix.

so back to using this yeast again!  my packs were best by november.  lag time was probably about 24 hours.  I pitched the yeast straight into primary with no rehydration.  OG was about 1.058.  10 gallons.  I set my temp controller to 66F.
