A Sommelier's Costco Sparkling Wine Cheat Sheet: Seven Bottles, $10 to $150

A certified sommelier walks the Costco aisles and picks seven sparkling wines worth buying, from $10 Kirkland Prosecco to $150 Henriot vintage Champagne.

This is a shopping list dressed as an article, and that's fine — because the person writing it actually knows wine. Brianne Cohen is a certified sommelier who buys in volume for tastings and events, and Costco is where she goes when she wants good bottles without the markup. The list runs from a $10 Kirkland Signature Prosecco to a $150 Henriot vintage Champagne, with useful stops in between. The Kirkland picks are the real story here. The Prosecco comes from the Superiore designation — a stricter production zone within the broader Prosecco region — and costs roughly $10. The Kirkland Brut Champagne runs about $21, which is genuinely unusual for real Champagne in a full-size bottle. These are the Costco-specific finds you can't get elsewhere, and they're where the value argument is strongest. The branded picks are solid but less surprising. Moët & Chandon is Moët — you already know what you're getting. Cohen's real enthusiasm shows for Roederer Estate, the California sparkling made by Louis Roederer's Anderson Valley operation. At $20-30 versus $60-80 for the French parent label, the price gap is real, and Cohen liked it enough to serve at her own wedding. That's a recommendation with skin in the game. The Blanchard Perez Cava under $10 is the sleeper pick. Cava uses the same traditional method as Champagne (second fermentation in bottle) but Spanish land and labor costs keep prices down. If you like dry, crisp sparkling and don't care about the Champagne label, this is the rational choice on the list. The Scharffenberger Cellars sparkling rosé at around $20 fills the pink-bubbles slot without much elaboration. Cohen describes it as bright and light — fine for salads and shrimp cocktails. It's a competent recommendation rather than an enthusiastic one. The Henriot at $150 is the splurge pick, and there's an important editorial footnote: Cohen describes Henriot as an independent, family-owned house, but the editors note it was acquired by the TEVC cooperative group in September 2023. The wine itself — a vintage Champagne with single-harvest grapes — is a legitimate luxury bottle, but the independence claim is outdated. What this list does well is bracket the price range honestly. A $10 Prosecco and a $150 vintage Champagne are not competing for the same occasion. Cohen gives you a reason to buy at each price point without pretending they're interchangeable. What it doesn't do is compare to non-Costco pricing or explain how much you're actually saving — the value proposition is asserted rather than demonstrated.
