Though Americans don’t usually commemorate all dozen days of Christmas, Perch Pub is giving Philadelphians 12 reasons to celebrate. Starting Tuesday, December 11, a different rare seasonal beer will be offered. All bottles from the winter brews will be collected and used to create a nine-foot beer Christmas tree at the end of the 12 Beers of Christmas promotion.

The holiday ale lineup includes favorites like Troegs Mad Elf and Anchor Christmas Ale, and other rarities like Penn Brewing St. Nikolaus Bock and Brasserie DuPont Avec Les Bon Voeux. The price and ABV of these 12 special beers varies quite a bit, from $5–$22 and 5.5%–11.5%, respectively.

In case you needed more incentive to drink the good brew, proceeds from the purchase of these beers will be donated to the Salvation Army. Check out the full list of what you’ll find each day through December 22 at the second-floor Broad Street bar, below.
