pitching yeast in cold wort? Bad?

[Jon112]

Guys,

last night I made a batch of beer, and I was in a bit of a rush. I rehydrated my yeast as I was adding the cold water to my wort. The yeast foamed up nicely and I was about to ad it to my wort but I noticed the side of my carboy was pretty cold. I filled it up all with cold tap water, and I think it was a little TOO cold. Not freezing, but colder then I would have liked it.

I was going to wait for it to warm up, but It could have been a few hours, so I pitched the yeast. Its been about 18 hrs and no activity. I read that it can take longer if you pitch in cold wort and it should be ok, but I would like a second opinion.

I figure if I dont get any activity in a few days I will repitch yeast,, but I had a beer kit and not sure if I can get the same yeast, would this matter?

The only activity you need to look for is with a hydromter.....

When the wort warms up, the yeast will get back to work. Just relax.....You can't kill the yeast in the cold, just put it to sleep. It will wake up when it gets into the right range.

After 72 hours take a gravity reading and see what's going on. It's quite common for yeast to take 2-3 days to get going anyway, it's called lag time.

It IS a sticky at the top of the beginners forum for a reason, afterall.

Yeah, I wasnt too worried but just not sure if the cold would kill it like hot water can. Thanks
