Jolly Pumpkin Artisan Ales
Jolly Pumpkin Artisan Ales was founded in 2004 by Ron and Laurie Jeffries in Dexter, Michigan, and became the first all-wild, oak-aged brewery in the United States. Brewer Ron Jeffries began studying brewing science in 1991 and started brewing professionally in 1995 before launching Jolly Pumpkin to pursue old-world rustic styles. All beers are unfiltered, unpasteurized, and aged in oak — including wine barrels, bourbon barrels, and large foudres — where naturally occurring microflora including Brettanomyces create complex, earthy, and funky flavor profiles. The brewery has earned numerous awards and is widely recognized as a pioneer of the American sour and wild ale movement. Founder Ron Jeffries passed away in 2024.

How we measure this
Two thresholds are at work here:
- The signature list shows notes that recur in at least 6% of this brewery's beers. A low bar — enough to flag a pattern, not high enough to call it an exclusive trait.
- The peer comparison below shows only notes where this brewery's coverage differs from similar breweries by at least 20 percentage points. A higher bar — enough to call a real difference, not a nudge.
A note can appear on the signature list without appearing in the peer comparison: it recurs here, but similar breweries do the same thing.
La Roja
Their beers place in the Top 55% of the catalogue on average, across 15 ranked beers. One clear standout well ahead of the rest.
