Costco and Aldi are quietly hiding $150 premium Napa Valley wines under their private labels for less than $30 due to a massive industry surplus

Wine lovers, your next grocery run just got a major upgrade.

According to KTLA 5, California wineries are currently struggling with a massive oversupply of premium wines.

To clear out their massive inventory, they are quietly selling their high-end products to major retailers at a fraction of their usual prices.

Score top-tier wine at discount stores

This industry surplus is a massive win for everyday shoppers. Retailers like Costco, Aldi, Kroger, and Grocery Outlet are now stocking high-quality wines that typically cost over $150 a bottle.

You can easily grab these premium pours for less than $30 under private or exclusive store labels.

In some cases, the discounts are even steeper. At Grocery Outlet, a Napa Valley cabernet sauvignon originally priced between $45 and $85 is currently selling for just $9.99.

You will find it hiding under the retailer’s “Second Cheapest Wine” brand.

Why is premium wine so cheap right now?

This massive bargain is the result of a yearslong market imbalance. California accounts for roughly 80% of the nation’s wine production, but Americans are simply drinking less wine.

This shift left wineries with growing inventories of unsold bottles.

To unload this excess supply without undercutting their established brands, producers are selling in bulk. Retailers then repackage the premium wine under their own private labels.

Steve Beckner, a wine buyer for Grocery Outlet, noted that bulk wine offers have skyrocketed. When he started in 2018, typical offers ranged from 1,000 to 3,000 cases.

Now, retailers are seeing bulk offers ranging from 20,000 to 200,000 cases.

The quality is better than ever

Because there is so much surplus, the wine hitting the discount shelves is incredibly high quality. At Kroger, the grocer went from having zero wines scoring 90 points or higher to stocking 20 highly-rated wines in just two months.

Costco also slashed the price of its Kirkland Signature Stags Leap Cabernet Sauvignon down to $19.99.

Industry analysts blame the overall decline in traditional wine sales on changing drinking habits and inflation.

Americans purchased an estimated 329 million cases of wine in 2025, down from 335.9 million the previous year.

How long will the deals last?

While this is a dream for bargain hunters, it puts heavy financial pressure on California’s grape growers.

Many growers are already pulling up vineyards or switching to other crops to survive. Between 2024 and 2025, more than 38,000 acres of California vineyards were removed.

Fortunately for shoppers, these steep discounts will not vanish overnight. Experts estimate it will take another 12 to 24 months for the market to work through the remaining surplus.

That means you can continue finding premium California wine at unusually low prices well into the coming years.
