I have done a chocolate cherry stout from extract and real sour cherries with dark chocolate. It was very good. I did not use mixed gas to carbonate it . Should it be carbed with c02 then switched to mix 75 nit 25 c02 when serving or carbed with mix from the very start of carbonation????
Somebody posted about this a few weeks ago... I kegged the AG version yesterday and pitched another beer onto the 1028 cake. It's one of my favorite homebrews, this is the first time I've made it myself but I've had it several times at the club meeting brewed by other folks. This recipe wins lots of medals at comps too.
