US05 ideal temp

[ballsy]

Using this for first time in a 1.044 OG APA. Rehydrated as usual. Pitched into 58deg wort. I am used to about 60 deg F ambient in swamp cooler (esp with notty), but there was no airlock activity after 24hrs so I let the swamp cooler warm to about 63-64 after 36hrs and magically the blow off tube starts a bubblin. I thought maybe was just lag time and not temp related so tossed a couple frozen bottles in to get ambient back to 60 and the bubbling stops...then as soon as ambient creeps up to 62-63....bubbling again! I know it has 59-72 deg range roughly and my guess is ferment temp is around 67 with ambient at 62-63...guess this strain prefers a little warmer?

If you have a decent sized swamp cooler, the wort is probably within a degree of the water temp. I guess you are just sitting around it's lower temp limit.

I actually have a beer with the same OG as yours that I'm about to rack that I am fermenting with 05 at about 62-64 with no problems. I'd try keeping it in that range and see what happens.

I've wondered this...so ambient air temp won't hold ferment temp as well as swamp cooler? I.e. 65 deg air ambient will have a warmer ferment than 65 deg water ambient?

Yeah, she seems real happy at 63ish...bubbling nicely.

Fermentation can raise the beer temp. by 5-10 degrees, so with an ambient
temp of 65, the beer will be 70-75 Degrees. Too warm..

True for air, but if he's measuring the water temp in the swamp cooler, that's going to be fairly close to your beer temp (maybe a degree below).

US-05 is quite happy in the 64-66*F range.

I use US-05 a LOT. I've never pushed the lower end of the spectrum, but I can say that it does quite well in the 64-68 F range.

Great observation. It really doesn't like it at 59, yet excels at 62 F ambient and a little warmer ferment. It's not Notty as you note. US-05 is just so clean, and great with big hoppy beers.

First time with US-05? Try it in a big american stout, IPA, or barleywine. Underpitch it, honestly I use one pack of dry and don't rehydrate, and have won that way 3x in BJCP competitions. The temperature is the key, and it's not a super fast starter figure a day minimum but once going pretty strong yeast.

Well you found its temperature sweet spot, it's truly a winner yeast in the big American ales from my experience.

I keep the thermometer in the water, resting b/w the ferment bucket handle which holds it against the outer bucket wall. Thanks for clarifying this, I was always worried the inner ferment temp would still be the proclaimed "5-10deg's warmer then ambient" so I have always kept the water at 60 to be safe.

hmmmmm...a Black IPA was on my "to do" list!!....Thanks!

My normal range for US05 is 62F - 75F. I haven't noticed a huge difference thru the range either. I've easily done 50+ batches with this strain too.

 

[Fordzilla]

I almost exclusively use US-05. I set my fermentation chamber to 62 F, which reads from a quart jar full of starsan, so it should be very close to the beer's temp. I have good results.

Works great for my chinook CDA!
