A kind word of caution. I just finished up a Wee Heavy which I mashed at a slightly higher temp, caramelized 1.25 gallons of wort, & did a 2 hour boil. Anticipated FG was 1.024 actual FG was 1.030. Also there is a rather strong alcohol presence in this 8.5% abv bier at about 3 months. I fermented in the 62-66 degree range and pitched a 1-gallon starter of Edinburgh yeast. All that's to say I think i created too many long chain sugars in my wort by tripling my 'caramelizing' efforts. This obviously caused a bump in FG & I feel it stressed the yeast who were trying to eat these complex sugars resulting in the higher alcohols.
If I had it to do over again I'd mash at 152 rather than 155 for my initial step of 30 mins, reduce the long boil to 90 mins from 120, and caramelized runnings as stated above. The alcohols will tone down/disappear with time so no worries there, but the initial tasting is quite cloying. On the good side the caramel & burned sugar flavors are out of sight with quite a complex maltiness to be so young!
Good luck & Schlante,
Phillip
