I once had a valve fail on a glycol loop (it stayed open) and crashed a fermenting batch of 1.090 beer to 45 degrees on US-05 and the yeast was chugging along like nobodies business. It eventually warmed up into the lower 60s on it's on once I got the glycol shut off. Attenuation was right where I wanted it and taste was clean, no off flavors at all.

Early on in my career I was working in a brewery with no air conditioning, so in the winter I'd have to knock out in the 70s and by the time fermentation was wrapping up the beers were in the 40s. I won a couple awards for a "lager" brewed with that schedule and S05. :o

Upper 50's? It will effectively ferment into the lower 50's.

I once had a valve fail on a glycol loop (it stayed open) and crashed a fermenting batch of 1.090 beer to 45 degrees on US-05 and the yeast was chugging along like nobodies business. It eventually warmed up into the lower 60s on it's on once I got the glycol shut off. Attenuation was right where I wanted it and taste was clean, no off flavors at all.

You may have created the first "lagale"!  Glad it worked out.  WY1056 and US-05 seem to be very hearty and flexible.  I have never had a bad brew with either.

Personally I haven't used WLP001 or 1056 in many many years so I can't speak to that.  In fact I'm on a quest to find the best 21st century dry yeast for every beer style under the sun.

+1. I'd like to get your notes.

My experience is US-05 is a very forgiving and dependable yeast no matter what I do.

I pitched -05 in Yooper's Fizzy Yellow Beer at the new 64*F. It turned out great.

Does anyone here re-use their US-05?  I have never re-used it before but thought about doing it after it's done with the APA it's currently working on.

Sure, go right ahead.

My reuse of dry yeasts is diminished in the warmer months.  The higher potential for contamination (airborne microbes here in the Midwest) and the lower cost of the dry yeasts makes it worthwhile to just buy more during the warm months.  I re-use my liquid lager yeasts, but I am meticulous in the warmer weather regarding harvest and sanitation of those strains.  Last year I abandoned the use of virtually all liquid yeasts in the summer and pitched S-189 for my lagers.  My LHBS gave me a good deal by agreeing to split a large order of S-189 with me at a reduced per packet price (I think it was a 20 sachet package that we split). 

YMMV, of course and if you can keep it clean, it re-pitches pretty well.

I have reused it many, many times.

I've never gotten "peach" at low temps with US-05, but I have gotten peach from it once, when fermenting at ambient during a freak heatwave. I didn't know the difference between fermentation temp and ambient temp at the time and figured 72F was a find fermentation temperature... of course ambient ended up being over 80F the next day in my south-facing 4th-floor apartment.

Now, I have had inconsistent US-05 lately, and I think it comes from how well the packs were stored. With 001 or 1056, the starter I build usually mitigates that inconsistency.

hey! hello...i was looking for any experimental data on US05 fermented above 70°F so i got here... i read a few interesting things and i want to share an experinece that happened to me few years ago; I was using a chico straing (blend of 2 Chico´s) and happened this phenomena in which Temperature control got crazy and super cooled the FV, so the unitank was around 35°F (1.6°C) and the yeast was still fermenting!!!! bubling a lil bit but it was alive! incredible.... after that, it raised temperature so slow but diacetyl was still there on finished beer....American Butter Amber Ale...............
cheers!
