Truly Grapefruit Seltzer 6Pk

Truly Grapefruit Seltzer 6Pk is a hard seltzer made from fermented cane sugar at 5% ABV, sold in a six-pack of 12 oz cans. Produced by Boston Beer Company — the same brewery behind Samuel Adams — Truly distinguishes itself from most competitors by adding Mandarina hops after fermentation, lending a subtle mineral complexity that rounds out the grapefruit character.

Production & Heritage

Boston Beer Company, founded in 1984 by Jim Koch, launched the Truly Hard Seltzer line in 2016, entering the flavored seltzer category shortly after White Claw. Unlike most hard seltzers that rely on a simple base of fermented sugar and water, Truly undergoes fermentation of cane sugar followed by the addition of hops — specifically Mandarina hops — a step that adds a faint minerality and textural depth uncommon in the category. The grapefruit expression uses natural flavoring to achieve what tasters consistently describe as an authentic, unsweetened citrus profile rather than a candy-like imitation.

Tasting Notes

Aroma: A lilting citrus character rises from the can immediately — bright pink grapefruit rind leads, followed by a clean, lightly mineral undertone. The nose is refreshing and convincingly fruit-forward without any artificial sweetness.

Taste: The entry is tart and direct, delivering rich pink grapefruit flavor that reads as close to fresh-squeezed juice. A sassy sourness builds at mid-palate, punctuated by a slight bitterness that mimics real grapefruit pith. The hop addition manifests not as a hoppy beer note but as a subtle mineral backbone that keeps the seltzer from tasting hollow.

Finish: Crisp, clean, and moderately short with lingering citrus acidity. The bitterness fades quickly, leaving a dry, refreshing close that invites the next sip.

How to Drink Truly Grapefruit

Straight from the can, well-chilled, is the most popular serve — the flavor is calibrated to stand on its own without garnish. Pour over ice in a tall glass with a grapefruit wedge for a slightly more composed presentation. For cocktail riffs, try a Paloma Spritz, replacing club soda with Truly Grapefruit to add effervescence and alcohol in one pour alongside tequila and lime. A Greyhound Shandy blends the seltzer with a splash of fresh grapefruit juice and vodka for a low-ABV afternoon drink. It also works well in a Seltzer Aperol Spritz, standing in for prosecco to create a lighter, more citrus-forward version of the Italian classic.

Why Truly Grapefruit?

The addition of Mandarina hops is the single most meaningful production choice separating Truly from the majority of hard seltzers on the market — it introduces a layer of mineral texture that prevents the liquid from reading as flavored sparkling water with alcohol. The grapefruit expression showcases this best, because the hop character complements rather than competes with citrus bitterness. Taste of Home testers singled out Truly's citrus lineup for "spot-on fruit flavors," noting that the grapefruit "tasted like the real deal." For anyone seeking a hard seltzer that leans tart and refreshing over sweet and artificial, this remains one of the most reliable choices in a crowded field.
