Keep in mind that Lambic brewers use a cool ship and I would assume that a lot of the break material gets left behind in it when they transfer out of it into the barrels. I brewed 12 gallons of a spelt pLambic with ECY20 a few weeks ago and did an overnight no-chill in a half bbl sanke. The next day, I transferred off the break material into another keg and pitched. Lots of break material got left behind.
