Grillo's Pickles and PopUp Bagels are reprising their brand partnership with a new limited-time offering: Grillo's Hot Pickle Butter, a compound butter built on Grillo's pickle profile and available exclusively at PopUp Bagels locations nationwide from May 28 through June 10, 2026.

The 14-day window is tight by any LTO standard. PopUp Bagels, which operates under the self-styled tagline "Not famous but known," is distributing the product while daily supplies last — a scarcity mechanic that functions as both a demand driver and a hedge against overproduction. No unit count or per-door volume figures were disclosed.

For Grillo's, the collaboration extends a retail-to-foodservice crossover strategy that has become increasingly common among branded CPG players looking to generate trial and brand impressivity at the point of consumption. Compound butters occupy a high-margin, low-labor position on a breakfast menu — no cooking, minimal waste, and strong attachment rates to a core carb vehicle. For PopUp Bagels, a specialty operator competing in the fast-casual breakfast daypart alongside an expanding field of independent and regional bagel concepts, a branded schmear alternative adds menu differentiation without a permanent SKU commitment.

The broader breakfast segment continues to attract LTO investment as operators chase the daypart's relative traffic resilience. Morning occasions have held up better than lunch in recent comp-sales data across fast-casual peers, and limited-run flavor collaborations have proven effective at generating earned media impressions that offset paid marketing spend — particularly for digitally native brands like PopUp Bagels that built initial awareness through social channels and pop-up distribution before moving into permanent brick-and-mortar footprints.

Neither party disclosed financial terms of the arrangement, wholesale pricing, or royalty structures. Distribution is retail-adjacent rather than broadline, meaning execution depends on direct brand-to-operator supply chain coordination rather than a distributor network. That model limits scale but preserves brand control — a trade-off both Grillo's and PopUp Bagels have historically favored. Operators tracking the specialty-ingredient collaboration space will want to watch whether the two-week sellthrough justifies a more extended or permanent menu placement in a future agreement.
