Dry US-05 slow start in cold wort

[mucci2k]

I pitched dry US-05 into 60 degree wort and it hasn't taken off in 24 hours. Are the yeast still sleeping? Should I heat up the bucket to kick start it? I stirred it to make sure the yeast didn't all sink to the bottom.

I'd probably wait, until you have the capacity to bump it up to 62-64 without overshooting. The worst would be to get antsy, get the temp too high and have off-flavors than just waiting it out.

I assume this was a fresh packet of yeast, not something funky like recycled and or old/stressed yeast? Normal OG wort, etc,?

yep, less than 6 months old that was kept in the fridge.

dry yeast 6 mo in fridge or recycled yeast slurry?

sorry, fresh packet.

6 months old shouldn't be a factor however, pitched dry and 60° doesn't surprise me that it's getting off to a slow start.

I've found my beers take off much quicker when I rehydrate the yeast. I think you'll be fine, just have a bit longer lag time.

I expect to see activity start at 30 to 36 hours in with my dry yeast rehydrated but into cold wort. Patience.

You'll be fine. US-05 is slower in the cooler temps, but makes a more gooder beer IMHO.

I did send thing with my us05 after 2 1/2 days I warmed. To 70 degrees and took off. Turned out delicious

Pitched some recently at normal temp and didn't see any krausen for about 36 hours or so, all was fine.

have you aerated properly?

Stirring isn't enough, you need to give it a very, veerrrry, good shake.
