🎃🍂 PSL IS HERE🍂🎃

Forget the latte—this is the real PSL. Our Pumpkin Spiced Lager is crisp, amber, and brewed with all the cozy fall flavors you crave: cinnamon, nutmeg, clove, and just a touch of pumpkin sweetness.

It’s sweater weather in a glass. Perfect for leaf peeping, pumpkin carving, or just embracing your inner fall vibe. 🍁✨

👉 Grab it while it lasts—because like the season, it won’t stick around forever. Available now on draft and in cans to-go.

🥭🍊 RADIANT DAYS ARE BACK! 🍊🥭

Radiant Days: Papaya Tangerine Fluff makes its return when we open tomorrow!

This 4.9% Double Fruited Sour is absolutely loaded with papaya, tangerine, and marshmallow, bringing together juicy tropical fruit and bright citrus with a soft, fluffy sweetness on the finish.

Think fruited vanilla smoothies, fresh-made gelato, and a splash of tropical sunshine—all packed into one seriously refreshing sour.

✨ Portals: Dragonfruit & Passionfruit incoming! 🥭

Bright, vibrant, and packed with tropical fruit, this one is erupting with flavors and aromas of juicy dragonfruit, tangy passionfruit, açaí bowls, and delicate hibiscus petals. Lush tropical sweetness meets a refreshing tart finish for a beer that’s as colorful and festive as it is delicious.

🫐🧇 A FAN FAVORITE IS BACK! 🧇🫐

Late Nite: Blueberry Waffles has officially returned!

Part of our 8.1% ABV dessert-inspired Imperial Sour series, Blueberry Waffles is loaded with flavors of macerated blueberries, stacks of fluffy waffles, and Maine maple syrup. Sweet, tart, decadent, and unapologetically dessert-like.

And when we say “fan favorite,” we mean it. During our fifth anniversary bracket-style contest, you voted Blueberry Waffles the best beer we’ve ever made.

Now it’s time to see if it still holds the crown. 👑

🍺 On draft NOW
🫐 4-packs available TOMORROW

Welcome back, Blueberry Waffles!

Our staff loves drinking Definitive as much as you do. 🍻

When she’s off the clock, Dana loves our sour, Rita Raindrops — a margarita-inspired sour that’s fruity, tart and sweet all at the same time.

Jane loves all kinds of beer, but she’s especially loving our TDH Definitive IPA — our flagship IPA, but triple dry hopped!

🍫🥜 PIECES IS BACK! 🥜🍫

One of our favorite stouts has made its return.

Pieces is a 7.2% Double Milk Stout packed with rich, decadent flavors of fresh-baked chocolate muffins, peanut butter frosting, and chocolate cereal milk. Sweet, smooth, and dessert-like, it’s basically breakfast in a glass—if breakfast were a Double Milk Stout.

This one is a small batch, so don’t wait around.

🍺 Available now on draft and in 4-packs to go on Friday!
