And how much?
Just added a few drops to a glass of this (http://www.nationalhomebrewclub.ie/cgi-bin/yabb2/YaBB.pl?num=1347793863), which is already fairly flavoursome, but didn't really get any much hint of chocolate.
I added mine straight to the bottling bucket with the priming sugar, 30ml in a 23l batch. Or you could just bung it into the keg when kegging. TBH if I was doing it again I'd add more, maybe even 50-60ml in a 23l batch for a more full choc aroma.
I bottled a rye brown ale tonight, and added 1.5ml of choc extract to 10 of the bottles.
Results in a couple of weeks...
I just chucked in the whole bottle of extract yesterday. Still didn't excite me after a quick taste. Will report back in a few weeks once the bottles are conditioned.
I think it should give more of a choc aroma than flavour. Carbonation should help the aroma ;)
Where did you guys buy chocolate extract ?
I opened a bottle yesterday, only a week but was carbonated. Didn't get any chocolate off, looks like the extract was a waste of time. Had better results with just malts.
Will try another in a couple of weeks and see what changes a bit of conditioning does.
