Morning,

I brewed an extract batch last night. Had around 12L of boiled wort which I cooled to about 40 celcius and then put it into the FV with cold bottled water to top up to 21L.

I miscalculated how much the the cold top up water would bring the overall temperature down. It went down to 16 celcius and so waited until it warmed to 18 celcius to pitch some US-05.

From what I've read, ideal pitching temperature is about 21 celsius, so have I pitched too cold? The packet of US-05 says the temperature range for the yeast is 12-25 celsius. Does that just mean that it will take longer for fermentation to start happening?

either or - you could have pitched at 16 and let the yeast and wort rise to 18 no problemo

I pitched a Dr Smurto's Golden yesterday with S-05 at 18 deg. This is the temp I've always used and never had an issue.

I pitched US-05 in my latest pale ale at 15 degrees and fermented out at 17 degrees. Tastes great.

It'll be fine, but you may experience a little more lag. The trick is not to worry.

You only have a 2 inch gut? You need to brew more.
