Production & Heritage

Phase Three Brewing Company operates out of Lake Zurich, Illinois, and has built a devoted following in the Midwest craft beer scene for boundary-pushing sour ales, stouts, and IPAs. The Frog Stack line is a gose brewed with black rock salt, then conditioned on generous amounts of fruit purée after primary fermentation—a technique that preserves bright, fresh fruit character rather than fermenting it away. The Peach Blackberry variant layers stone-fruit sweetness against darker berry tartness on that salted sour foundation.

Tasting Notes

Aroma: Ripe peach leads immediately, followed by a jammy blackberry undercurrent and a faint mineral salinity. The nose is fruit-forward without smelling artificial or syrupy.

Taste: The entry is tart and bright, with juicy peach dominating the front palate. Mid-palate, blackberry steps in with a slightly tannic, berry-skin complexity, while the black rock salt provides a savory backbone that keeps the sweetness in check. The overall mouthfeel is creamy and rounded, consistent with the broader Frog Stack series.

Finish: Short and refreshing, as expected at 4.5% ABV. Lingering peach sweetness fades into a mild saline note that invites the next sip.

How to Drink Frog Stack Peach Blackberry

Pour cold into a tulip glass or wide-mouth goblet to let the fruit aromatics open up; this beer drinks best fresh and well-chilled. At 4.5% ABV, it works as a standalone refresher, but it also has cocktail-adjacent versatility: use it as the base in a Beer Shandy blended with fresh lemonade for a summer crusher; float it atop a Berliner Radler with grapefruit juice for a layered citrus-and-berry drink; or pair it with a splash of elderflower liqueur in a Gose Spritz served over ice for a low-proof aperitif.

Best For

• Warm-weather sessions where low ABV and high flavor are equally important
• Introducing sour-curious friends to the fruited gose category
• Pairing alongside a weekend brunch spread
• Adding variety to a craft beer tasting lineup heavy on IPAs and stouts

Frequently Asked Questions

What foods pair well with Frog Stack Peach Blackberry? Try it with fresh goat cheese and arugula salad, where the salt and tartness complement the cheese's tang; grilled shrimp tacos with mango salsa for a fruit-on-fruit pairing; a charcuterie board featuring prosciutto and stone-fruit preserves; vanilla panna cotta for a dessert contrast; or a light Thai papaya salad where the beer's salinity echoes the fish sauce notes.

Why Frog Stack Peach Blackberry?

The Frog Stack series has earned strong marks from the craft beer community, with variants in the line scoring as high as 4.77 out of 5 on BeerAdvocate. What distinguishes the Peach Blackberry release is its particular fruit pairing: stone fruit and dark berry create a broader flavor spectrum than single-fruit goses, while the black rock salt base keeps everything grounded and drinkable. At just 4.5% ABV, it avoids the heavy, boozy quality that plagues some higher-gravity fruited sours. For drinkers who want a beer that tastes genuinely like fresh fruit without sacrificing the complexity of a well-made gose, this variant delivers on that specific promise.
