In fresh yeast that is. I have been planning a Sammy Smith Nut Brown Ale Clone and called my LHBS last week about the Yorkshire Square Yeast which is rumored to be from the Sam Smith Brewery. They had one in transit and mailed it out the day it got in. The production date was 11/5 which means it was a week old. I made a 3L starter yesterday afternoon and by 11:00PM I swear it was done! In about a 3 hour span last night it went from small bubbles to egg drop soup. Truly amazing and the fastest I’ve ever had a 3L starter burn out. About 10 hours!
