Xül Beer Co PB&J Mixtape 4Pk is a gluten-free fruited sour at 6.5% ABV built on a seltzer base with real roasted peanuts and Concord grape. Rated 4.4 out of 5 on Untappd across more than 21,000 ratings, it has become one of the most talked-about specialty releases in American craft beer — a flagship offering from Knoxville's Xül Beer Company that reviewers routinely compare not to other beers, but to a liquid Smucker's Uncrustable.

Production & Heritage

Xül Beer Company brews out of Knoxville, Tennessee, where co-founder Brad West and his team have developed a reputation for adjunct-forward sour ales that push the boundaries of the category. PB&J Mixtape is technically classified as a fermented malt beverage (FMB), not a traditional kettle sour — it is built on a gluten-free seltzer and dextrose base, then finished with real roasted peanuts and real Concord grape fruit. The exact production method remains a closely guarded trade secret; West has publicly declined to elaborate beyond confirming the gluten-free base and the use of real roasted peanuts, stating the technique is too well-executed to reveal.

Tasting Notes

Aroma: Peanut butter dominates the nose immediately — both creamy and chunky in character — joined by a thick, jammy Concord grape sweetness. An underlying note reminiscent of white bread rounds out what multiple reviewers describe as the unmistakable smell of a peanut butter and jelly sandwich straight from the bag.

Taste: Grape jelly hits first, bright and sweet, before roasted peanut butter rolls in on the back end. The tart sour base provides crucial structure, keeping the sweetness in check and preventing the rich adjunct flavors from becoming cloying. The overall impression is remarkably food-like — jammy berry fruit balanced by smooth peanut butter, all riding on a clean, tart foundation.

Finish: Light and dry with moderate carbonation, the finish cleans up quickly without lingering heaviness. Residual peanut and grape fade gently, leaving a pleasant tartness that invites the next sip.

How to Drink PB&J Mixtape

Serve cold, ideally between 38–42°F, straight from the can or poured into a tulip glass to concentrate the peanut butter aromatics. This is a standalone sipper designed to be enjoyed on its own — its complexity comes from the interplay between roasted peanut, Concord grape, and tart sour base. It also works well as a dessert course pairing alongside vanilla ice cream or chocolate brownies, and stands up as a playful accent in a beer float built with vanilla bean gelato.

Frequently Asked Questions

What does PB&J Mixtape taste like? It delivers a remarkably convincing liquid peanut butter and jelly sandwich — bright Concord grape jelly up front followed by roasted peanut butter on the back end, all held together by a tart sour base that prevents it from becoming overly sweet.

How does PB&J Mixtape compare to traditional PB&J kettle sours? Unlike most PB&J-styled craft beers that use a standard kettle sour or grain-based platform, Mixtape is technically a fermented malt beverage built on a gluten-free seltzer base, resulting in a lighter body and cleaner canvas for the adjunct flavors. Reviewers consistently note that the peanut butter character reads as more authentic and roasted than in grain-based competitors, which the brewery attributes to the use of real roasted peanuts.

Is PB&J Mixtape good for sipping on its own? Absolutely — the moderate 6.5% ABV, light body, and balanced tartness make it highly sessionable despite the bold flavor profile, and most reviewers describe it as a beer best enjoyed straight rather than mixed.

Where is PB&J Mixtape made? PB&J Mixtape is brewed by Xül Beer Company in Knoxville, Tennessee, where the brewery has built a following around inventive sour ales and adjunct-driven releases.

What foods pair well with PB&J Mixtape? Vanilla bean ice cream or gelato complements the grape and peanut flavors without competing for attention. Dark chocolate brownies echo the roasted peanut notes. A charcuterie board with soft cheeses and fruit preserves mirrors the sweet-savory balance. Banana-based desserts like banana pudding play well against the peanut butter character. A classic PB&J sandwich leans fully into the theme.

What sizes does PB&J Mixtape come in? PB&J Mixtape is available in a 4-pack format, which is the standard retail configuration from Xül Beer Company for this release.

Is PB&J Mixtape worth the price? PB&J Mixtape positions as a specialty craft release in the premium tier of adjunct fruited sours, and its 4.4 Untappd rating across 21,000-plus reviews suggests strong consensus that the execution justifies the price point for drinkers interested in boundary-pushing flavor profiles.

Why PB&J Mixtape?

What separates PB&J Mixtape from the growing field of novelty-flavored sours is the execution. The proprietary process — so closely guarded that co-founder Brad West has declined to discuss it publicly — produces a beer that reads as genuinely food-like rather than artificially flavored, built on a certified gluten-free base that opens the door for drinkers typically excluded from the craft beer conversation. With a 4.4 rating on Untappd backed by more than 21,000 reviews, it has moved well beyond cult curiosity into verified crowd favorite. For drinkers who want a sour that delivers real roasted peanut character and authentic Concord grape fruit on a clean, light-bodied platform, Mixtape remains the benchmark.
