In Brew Like a Monk it was stated that the Monks from Westvleteren and Achel will drive to Westmalle and pick up a fresh pitch of yeast the day before they brew.
Interesting. However, the yeast I use for my Belgians I got from the bottom of a bottle of Westvletern, which came across the Atlantic ocean, was propagated from the dregs and performs like a racehorse. Much cooler conversation and story than I went to my LHBS and bought some WY3787.....
Absolutely! Culturing from a hard to get beer can be fun, and if it performed great, who cares ?
Exactly my point!
