Hi all.
I have just made up a batch of home brew larger. Whilst making it all up, the instructions said put in 6 pints of boiling water to the wart & sugar and mix then make up to 5 gallons. Pretty standard stuff, have done it a few times now. My question is - the temperature of the mix needs to be 18-21 degrees prior to putting in the yeast but as I put in 6 pints of boiling water, it took ages to cool down to 21 degrees, I had to put it in a bath of cold water to get it down at all. It took about an hour and a half or more.
Just wanted to know if that was ok really. Does it matter that I was waiting that long to put in the yeast?

Re: Too warm to add yeast to larger kit???
i would say it should be ok mate as long as you didn't get in the bath with it 
and you give it a good stir to oxygenate it before adding ya yeast..by the way it must have been pretty hot an hour and a half in a cold bath..

I doubt it, I've left a kit for 3 hours before (an ale kit), before adding yeast. I did re stir it though to get some air back in. It's turned out fine. As long as you keep a lid on, and keep dust etc out, whilst it's sitting there cooling down.

Hi Dan
I should think it'll be ok too. I would have added the yeast as soon as it was below about 25c rather than wait too long.
I only use enough boiled water to get it all out of the can, and then start adding cold water and when the FV is about half full I check the temp. to see how much hot or cold is needed. Takes a little practice but you can get it bang on this way. I needed to do this because I also add half a campden tab to the water and leave it over night in a spare FV or keg, so its not very cold when I come to use it.

Confession time. I've done quite a few kits over the last 12 months and I aint ever taken a temperature reading before pitching the yeast. Yup there's boiling water gone in, how much who knows. I just work everything by the 'aye that looks fine' rule book. Then the FV is topped up with cold water. Quick feel of the sides of the bin, not too warm, smashing, in goes the yeast. Now I've either been very lucky so far, or yeast is a lot tougher than we think.

hi
i follow the instructions on coopers european lager with all my kits think it's a good idea it says the following-
mix kit and sugar up with 2 litres of boiling water, top up to 20l with cold, then check temp, then top up to 23l with hot/cold or even ice to get to temp range. it says at this point the wort is vulnerable and prompt addition of yeast is more important than ideal temp. hope this helps

I've never had a problem - so long as temp is below about 28 degrees and falling, i just pitch - it's always worked for me.

Aye, I just suck some out with a tube, if it's luke warm, then in goes the yeast. I've even dipped me gammy mits in and nothing happened. I think some folks are over cautious with sterilising. I've NEVER had a yeast infection and all I use is household bleach in the fermenter.
