Our Saison style ale is our first true 'Brett beer' short for Brettanomyces which is yeast genus know to produce wild earthy like aromatics.  We added Brettanomyces cultures to our Golden Ale base after the primary fermentation with a Belgian yeast strain while in a Puncheon Barrel (500 L).  After about 3 to 8 months of aging the beer develops a new personality.  We then package a small amount of this aged beer and then top up the barrel using another Puncheon of the base beer, un-Bretted, this Puncheon is then retopped with another fresh batch of the Golden Ale, thus creating a SOLERA style of aging and a Goose that will lay Golden Beer!  Our base Golden Ale is made with a variety of base malts primarily Copeland from Fallon NV and then Thoroughbred 6 Row from Chester County PA among others so we have designated it 'Mixed Craft Malts'.   One finds that this beers aromatics are driven by the Brett rather than the source malts nuance thus a variety designation doesn't apply.  This beer is complex, vinous and mysteriously delicious although I have to say many of our wine focused friends are timid to its nature.  Our first release was a Members only release, Batch 28 (100%copeland).  We have another, Batch 50 , thats average age is 6 months in our Solera Puncheons(Copeland and Throughbred varieties).
