late hopping temperature

Post by Mauri » Thu Jul 30, 2009 9:02 pm

Hi all,
Today I was brewing a London Pride and I was going to use a hopping schedule which includes 15g of goldings being added after flame out, when the temperature has dropped to about 80C. Unfortunately, I was distracted (let's be honest, I was having a sandwich :D ) and the temperature dropped a little more than I was expecting. I ended up adding the hops anyway,even though the reading was 55C. I left it for the usual 20 minutes and carried on as normal. However I was wondering, will this affect the aroma that much? Is 80C a proven optimum point for this late hops addition? I mean, dry hopping is done at room temperature, but the smellies are still extracted into the beer, even though it normally takes place over a few days. Has anyone tested this?
This is just curiosity, as I'm sure the beer will be great anyway, and I think I won't bother with dry hopping to make up for any lost aroma anyway.
Cheers

My guess is that below 80c is the main criterion any higher and some of the oils would evaporate, and that between 70c-80c in the optimum temp for maximum extraction, just my guess though.

BTW I tend to add about 30g but that's just personal preference.
