Summer is when the wine aisle at Costco earns its keep. Members have spent the spring restocking for backyard dinners, holiday weekends, and the long stretch of warm evenings ahead, and a handful of bottles keep landing in cart after cart. Below are the ten wines drawing the loudest reviewer praise this season, with current shelf prices, tasting notes, food pairings, and a clear verdict on each.

How we picked these ten
Every bottle below is either an established Kirkland Signature exclusive that wine reviewers consistently rate above its price tag, or a brand-name pour Costco stocks at a meaningful warehouse discount versus the corner liquor store. The mix leans into what summer actually calls for — Champagne and Prosecco for celebrations, dry rose for the porch, crisp whites for seafood, and lighter reds that take a chill. Prices reflect recent warehouse sightings in May and June 2026; your local club may run a dollar or two higher or lower. BUY means a confident yes for most members. MAYBE means there is a specific limitation worth knowing before you walk a case to the register.
Sparkling
1. Kirkland Signature Brut Champagne (NV) — about $19.99
What it is: A non-vintage Brut Champagne made in Verzenay, a grand cru village in the Champagne region of France, blending Chardonnay, Pinot Noir, and Pinot Meunier. The wine spends at least 15 months on the lees before release.
The buzz: Reviewers at CostcoWineBlog rate this 91 points and consistently call it a stand-in for $40 to $70 grower Champagnes, while the CellarTracker community average sits at 87.6 across more than 500 ratings. Members in lower-tax states still find it at $19.99, which is about as cheap as authentic Champagne gets anywhere.
Pairs well with: Roasted chicken, oysters on the half shell, or a cheese course featuring aged Gruyere.
Verdict: BUY — Year after year, this is the best value in real French Champagne under $25.
2. Kirkland Signature Asolo Prosecco Superiore DOCG (NV) — about $6.99
What it is: An extra-dry Italian sparkling wine from the Asolo hills of the Veneto, the highest DOCG quality tier of Prosecco. Made from 100 percent Glera grapes at roughly 11 percent alcohol.
The buzz: Reverse Wine Snob calls it sensational value at under seven dollars and Reviewers note it tastes like a $15 to $20 Prosecco. Members who buy three or four bottles per visit have made this the workhorse summer sparkler for brunches and spritzes.
Pairs well with: Aperol spritzes, prosciutto and melon, or a Sunday brunch frittata.
Verdict: BUY — Outrageous price-to-quality. Stock the fridge.
3. La Marca Prosecco — about $11.99
What it is: The widely recognized green-and-blue-labeled Prosecco from the Veneto, made from 100 percent Glera and fermented in stainless steel to preserve a crisp, fresh character. Roughly 11.2 percent alcohol.
The buzz: A Wine Spectator Top 100 honoree, La Marca is the brand name many members reach for when entertaining guests who recognize the label. At under $12 at most Costco warehouses, it runs $4 to $6 below liquor-store pricing on the same bottle.
Pairs well with: Cocktail-hour appetizers, fruit-topped desserts, or a chilled glass with grilled shrimp.
Verdict: BUY — Pay the small premium over the Kirkland Asolo when you want a recognized label on the table.
Rose
4. Kirkland Signature Cotes de Provence Rose (2025) — about $8.99
What it is: A pale-salmon dry rose from the Cotes de Provence appellation in southern France, blending Grenache, Cinsault, Syrah, and Vermentino. Made by Olivier Sumeire, an eighth-generation Provence grower.
The buzz: Costco’s perennial summer hit jumped a dollar this year but still earned a 90-point score from Reverse Wine Snob, who described it as fresh, tart strawberry and melon with salty minerality. Members stock up by the case starting in May and the warehouses regularly sell out by August.
Pairs well with: Grilled salmon, Nicoise salad, or a charcuterie board on the patio.
Verdict: BUY — The summer rose other rose’s get measured against, at under $10.
5. Whispering Angel Cotes de Provence Rose — about $18.89
What it is: The flagship pale rose from Chateau d’Esclans in La Motte en Provence, blending Grenache, Cinsault, and Rolle (Vermentino). The bottle that arguably built the modern Provence rose category.
The buzz: Costco’s price runs roughly $5 to $7 below specialty wine shops, which is why members who entertain reach for this one when they want a name guests recognize. Tasting Table and The Kitchn both list it among the best rose’s available at Costco under $30.
Pairs well with: Grilled lamb chops, fresh tuna tartare, or a cheese plate featuring chevre.
Verdict: BUY — The recognized brand at a warehouse price. Buy two for one shelf and one for the cooler.

Crisp Whites
6. Kirkland Signature Ti Point Marlborough Sauvignon Blanc (2025) — about $6.99
What it is: A New Zealand Sauvignon Blanc from the Ti Point Vineyard in Marlborough. The same winemaker (Jeff Lee) told the Wall Street Journal in 2024 that this bottle stands up to Marlborough labels selling for three times the price.
The buzz: Reverse Wine Snob calls it on-point with vibrant lemon-lime, tropical fruit, and crisp acidity. At $6.99, it became the most-recommended Costco summer white among reviewers in 2026 — the price actually dropped a dollar from last vintage.
Pairs well with: Goat cheese salads, grilled white fish, fresh oysters, or a Thai green curry.
Verdict: BUY — Hard to beat at the price. Members who used to pay $15 for Kim Crawford keep migrating to this one.
7. Kirkland Signature Sancerre (2022) — about $15.99
What it is: A 100 percent Sauvignon Blanc from the Sancerre appellation in France’s Loire Valley, the source region for some of the most refined Sauvignon Blanc made anywhere. Imported by Misa Imports.
The buzz: True Sancerre rarely lands under $25 at retail; Costco’s $15.99 Kirkland version is one of the most quietly outstanding bottles in the warehouse. Reviewers describe it as solid, balanced, and unmistakably Loire — bright citrus, flint, and a chalky finish.
Pairs well with: Goat cheese tart, steamed mussels, asparagus dishes, or chilled lobster.
Verdict: BUY — A serious French white at a price that takes the gamble out of trying Sancerre.
8. Kirkland Signature Pinot Grigio Friuli (2024) — about $4.99
What it is: A DOC Pinot Grigio from the Friuli-Venezia Giulia region of northeast Italy, produced by Bottler S.p.A. Light, dry, and unoaked at roughly 12 percent alcohol.
The buzz: Costco’s least-expensive bottle on this list is also one of its most quietly competent. Reverse Wine Snob and Food Republic both flag it as the rare under-$5 wine that does not taste like an under-$5 wine, and it carries the DOC certification that guarantees the Friuli sourcing.
Pairs well with: Light pasta with olive oil, prosciutto-wrapped melon, simple grilled chicken, or a poolside afternoon.
Verdict: BUY — The least risky $5 in the warehouse. Pick up four bottles for the price of one mid-range white.
Whites with a Little More Body
9. Kirkland Signature Russian River Valley Chardonnay — about $12.99
What it is: A Sonoma County Chardonnay from California’s Russian River Valley, aged in French oak and bottled by DC Flynt MW Selections. Just a kiss of oak rather than the heavy butter-bomb style.
The buzz: Wine reviewers consistently compare it favorably to $25 to $30 Russian River Chardonnays. The Kitchn’s Costco wine roundup highlighted the Sonoma County Chardonnay line as similar to La Crema “at an incredible price point” — at $12.99, the price is roughly half what La Crema runs at the same warehouse.
Pairs well with: Roast chicken, butter-poached lobster, creamy pasta, or a board with brie and pear.
Verdict: BUY — The best California Chardonnay value at Costco, full stop.
Lighter Reds That Take a Chill
10. Kirkland Signature Russian River Valley Pinot Noir (2024) — about $10.99
What it is: A Sonoma County Pinot Noir from the Russian River Valley, light to medium-bodied, with the silky red-fruit character that makes Pinot the easiest red to drink in warm weather. Costco exclusive.
The buzz: The 2024 vintage dropped a dollar to $10.99 — the second consecutive year of price reduction. CostcoWineBlog rates it a solid summer-weight Pinot at a price that makes most California Pinot Noir from this region look overpriced. Give it 15 minutes in the fridge before pouring.
Pairs well with: Grilled salmon, mushroom dishes, charcuterie, or a Sunday burger off the grill.
Verdict: BUY — The summer red that does not feel heavy in 90-degree weather.
A few honest caveats
Costco wine inventory varies by state and warehouse far more than the rest of the store. Pennsylvania, Utah, and a handful of other control states will not carry any of these. Some bottles like the Sancerre and the Brut Champagne are seasonal allocations rather than year-round stock, so when you see them, do not assume they will still be there next month. Prices listed above are the most commonly reported figures from May and June 2026 reviewer write-ups; your local club may run a dollar or two different, and California-only formats (like the Veuve Clicquot two-pack with ice jackets) are not included here because they do not ship to most warehouses.
If you only buy three bottles from this list before the Fourth of July, make them the Kirkland Brut Champagne, the Kirkland Cotes de Provence Rose, and the Ti Point Sauvignon Blanc. That trio covers the brunch, the patio, and the dinner table for under $36, and there is not a weak link among them.
