Just tasted the resulting beer... it tastes so close to Chimay I was astounded. Seems like the yeast flavour profile makes up damn near 100% of the taste of Chimay.
Thomas: I sterilised two bottles and filled them with the yeast slurry post-wash. I could try to slant them myself (if I can get a lamp, loop, and some slants), or you can take one and do the honours. After trying the resulting beer I'm absolutely positive that I want to brew a clone ASAP. How long will this stuff last in the fridge, assuming I step it back up with a starter? I've read one week, two weeks, etc -- but I figure if the slants keep indefinitely, why wouldn't this?
