I had a smack pack dated April so I thought this might need some encouragement. Took it out of the fridge, smacked, and let it sit. 2h later there were already signs of action. Overnight it was puffed up and raring to go.
Started in a 1l starter showing plenty of krausen (most I've seen on a starter to date).
I decanted the starter on the grass which was made from kettle leftovers from an oatmeal stout. Oh, the smell. Intoxicating. Should have bottled it.
Put in a dry stout at 1.055 Sunday midday and yesterday afternoon it was already down to <1.040. I might even have a free fermenter for an English Barleywine this weekend at this rate.
