Seriously, it was so close that it actually "clapped". Now I know where the term "thunder clap" came from. So close it could have struck me. But I'm too pretty for that.
Gonna test the RIS tomorrow, see where the gravity stands. I lost almost a half gallon of liquid during primary fermentation because the damn thing overflowed. Good, healthy yeast starter combined with more yeast nutrient in the boil and almost six gallons of wort (as opposed to my usual 4.5 or 5) spelled disaster for the cleanliness aspect of my pantry. And I got sprayed in the face when I removed the airlock. That was actually kind of funny.
Here's the plan: If the beer is underattenuated, I'm gonna steal some yeast from the trub, make a "restarter", and see what few extra gravity points I can whittle away from it. Worked well for the coffee porter I did a while back, why not for the RIS?
Ordering my barrel today, too. I'm excited. Two and a half gallons of oak-aged, delicious (hopefully) Russian Imperial Stout await. In about three or four months, that is. The rest will be bottled, with some of those bottles more than likely being used to top up the barrel.
This stuff is getting heavy, and it's only the beginning. And I'm loving every minute of it.
