I'm sampling one that I bottled 2 weeks ago as we speak... which may not help the original poster two years ago (Unless Virtual Wayne finished that time travel software already) but may help other Pilgrims in future.
(Later note: Ah... I see that another poster covers this. Noted, and thanks, Cousin!)
I suggest that if you do this experiment that you keep an eyeball on the gravity because 3 days in Primary and 18 days in the secondary wasn't enough time. My FG at bottling was 1.020 (OG was 1.049).
When I used Champagne yeast for mead in 05, it went to the tertiary, several months before it cleared, and about a year in bottle before it was Most Excellent. Only a few bottles left by that time... so there ya go.
After 2 weeks in bottle, this Champale clone is ok and needs to carbonate further... and probably bottle finish before it is tolerable Lawnmower Beer.
BTW: Google Champale. Interesting historie... I recall it from the days of my mis-spent you't....
