San Diego's Karl Strauss, Berkeley's Fieldwork collab on Field Trip Hazy IPA

SAN DIEGO, Calif. – First to brew. Still pushing boundaries through innovation of what great handcrafted beer can be. Karl Strauss Brewing Company, San Diego’s first craft brewery, and Berkeley’s Fieldwork Brewing Co. are excited to announce Field Trip Hazy IPA, a Ridiculously Limited Release collaboration to be released on Thursday, August 6, that brings together two iconic independent California craft breweries, united by a shared belief that great beer starts the party.

Since igniting San Diego's craft beer movement in 1989, Karl Strauss has believed that the best beers come from the shared love of the craft. Whether it's experimenting with new ingredients, collaborating with fellow brewers, or introducing drinkers to something unexpected, Field Trip reflects the brave decisions that have always defined Karl Strauss and continues to drive independent craft beer forward.

At 6.7% ABV, Field Trip Hazy IPA strikes a balance between bold hop expression and exceptional drinkability. Brewed with Quantum Mosaic® from Abstrax and Citra hops, it delivers intense aromas of tropical fruit, ripe berry, bright citrus, and layered dank hop character, all supported by a soft, pillowy mouthfeel and smooth finish.

"Collaborations have always been one of the best parts of craft beer," said Karl Strauss Brewmaster Paul Segura. "They're an opportunity to learn from one another, experiment with new ingredients, and create something that neither brewery would have made on its own. Working with the talented team at Fieldwork made this beer especially rewarding."

"When we look at craft beer, Karl Strauss is one of the breweries that helped lay the foundation for everything that came after,” said Fieldwork Co-Founder and Brewmaster Alex Tweet. “As San Diego's first craft brewery, they've earned a legacy of innovation and quality that we have tremendous respect for. Collaborating on Field Trip was an opportunity to celebrate that history while creating something new together, and we couldn't be more excited about the result.”

This limited-run release will be available on draft and in 16-oz four packs across California, Arizona, and Nevada. But the best place to try it is where it all started, so visit one of Karl Strauss’s nine SoCal brewpubs, where the beer is fresh, the crowd is always ready to party, and the legacy of San Diego’s first craft brewery is alive in every pour.

To find Field Trip Hazy IPA, including retail outlets, visit Karl Strauss' Beer Finder. Karl Strauss brewpubs are located in Anaheim, Corona, Costa Mesa, Downtown Los Angeles, San Diego (4S Ranch, Carlsbad, Downtown, Sorrento Mesa), and Temecula.

As part of their community commitment, Karl Strauss will donate $1 from every pint of Field Trip Hazy IPA sold on release day at its nine Southern California brewpubs, plus 1% of this beer’s California retail sales, to the Restaurants Care program. This California Restaurant Association non-profit organization works to support and advance those at the heart of California’s food and beverage community during life’s most challenging moments. It's one more way Karl Strauss Brewing Company continues to invest in the community that helps shape the craft beer scene.

Karl Strauss last month was voted as the Best Micro Brew Pub in The San Diego Union-Tribune’s 2026 Readers Poll. It was also voted by the publication’s readers as a Favorite in the Craft Brewery and Downtown/Gaslamp Bar categories.
