Quick Facts: ABV: 5%  |  Origin: United States (multiple facilities including Glendale, AZ)  |  Style: Hard Seltzer  |  Producer: Mark Anthony Brewing

Production & Heritage

White Claw is produced by Mark Anthony Brewing, a subsidiary of the privately held Mark Anthony Group. The liquid is made through a proprietary process the company calls PureBrew, which begins with cold fermentation of a sugar and water base using a specially developed yeast strain that reportedly took a year to create. The base uses 51% sugar with trace amounts of malted gluten-free grains, and the Ruby Grapefruit expression incorporates natural grapefruit juice concentrate along with citric acid and natural cane sugar to achieve its signature citrus profile. Unlike malt-based seltzers from some competitors, this fermented-sugar approach gives the final product a notably clean, neutral backdrop for the fruit flavor.

Tasting Notes

Aroma: Bright, fresh-cut grapefruit peel rises immediately from the can, followed by a light, clean minerality. There is very little of the yeasty or grainy character sometimes found in malt-based seltzers.

Taste: The entry is crisp and dry, with zesty grapefruit hitting the palate first. Mid-palate brings a pleasant tug-of-war between gentle sweetness and citrus tartness, punctuated by a subtle bitter edge true to real ruby grapefruit. The carbonation is fine and persistent, keeping the mouthfeel light without feeling hollow.

Finish: Short and clean, leaving a faint grapefruit zest and mild dryness on the tongue. There is no cloying sweetness or artificial aftertaste, just a quick, refreshing fade.

How to Drink White Claw Ruby Grapefruit

Straight from the can over ice is the most popular serve, and the effervescence holds up well poured into a chilled glass. For a simple upgrade, try a Paloma Seltzer — pour over ice with a squeeze of fresh lime and a pinch of salt, as the grapefruit base does the heavy lifting normally handled by Squirt or Jarritos. A Seltzer Spritz works by topping a short pour of Aperol with a full can, since the bitter grapefruit notes mirror the classic Aperol Spritz flavor profile. You can also build a low-ABV Greyhound Highball by adding a half-ounce of vodka and garnishing with a grapefruit wheel, letting the seltzer's carbonation and citrus replace both the juice and the soda.

Best For

• Stocking a cooler for outdoor barbecues and pool days
• Offering a gluten-free, lower-calorie option at gatherings
• Casual weeknight drinks when a full cocktail feels like too much effort
• Introducing non-beer drinkers to a light, approachable alcoholic option

Why White Claw Ruby Grapefruit?

White Claw essentially created the modern hard seltzer boom and continues to hold roughly half the category's market share — not by accident. The PureBrew process and its purpose-built yeast strain give this Ruby Grapefruit expression a cleaner, more neutral base than many competitors relying on traditional malt fermentation, allowing the natural grapefruit juice concentrate to carry the flavor without interference. With over 22,000 ratings on Untappd and a 3.1 average, it has proven to be a reliable, if not polarizing, crowd-pleaser. For anyone looking for a straightforward, dry-leaning grapefruit seltzer that avoids artificial sweetness, this remains one of the benchmarks against which the rest of the category is measured.
