We have some excellent wines to recommend that are currently at many Costco stores. I, and other members of the Vintage Wine Tasting Club, have sampled plenty of wines over the past few weeks. We love these Best Buy Wines at Costco.
Prosecco Masottina

Janelle is a huge fan of sparkling wine. She has tried several and the Masottina is one of her favorites. The Masottima is light and spunky, with an amazing freshness of taste. The Masottina makes for a perfect aperitif. The alcohol is low. Decanter Magazine, one of the most prestigious wine publications, rates the Masottina at 96 points. The Wine Spectator score is 89 Points. If you like sparkling wine, you will certainly enjoy the Masottina at the affordable price of $8.99. Janelle ranks it at 90 Points.
What exactly is Prosecco? Prosecco is the name for sparkling wines that come from the Valdobbiadene region in Veneto, Italy. The grapes are Glera and often called Prosecco grapes. More information on What is Prosecco.
2018 Lost Hog Sauvignon Blanc Lake County
The 2018 Lost Hog Sauvignon Blanc Lake County is produced by the Dancing Crow winery in Lake County. Dancing Crow makes this Sauvignon Blanc exclusively for Costco stores. I spoke with a representative from Dancing Crow. He explained that the wine is in 20 Costco stores and selling briskly. “The price of $9.59 is rock bottom, an amazing price,” he states.

I agree with the Dancing Crow rep on this outstanding value of the wine. The style of the Lost Hog S.B. is similar to a French Sancerre. It is crisp, with some slight tropical notes. No big citrus flavors, just a gentle and seductive character. The Lost Hog is 100% Sauvignon Blanc. The grapes thrive in black clay soil at 1400 feet elevation. The vineyards are in the Big Valley AVA of Lake County. 89 Points
Two fantastic red wines

We reviewed both of these wines previously. We are recommending them once again because Costco has plenty, and they are such terrific wines. You cannot miss with these two awesome reds.
We love the 2015 Canoe Ridge Explorer Red Blend. Explorer Red is an excellent example of the fantastic wines coming from the state of Washington. We love the label, but the wine even more. $15 at Costco and $20 elsewhere.
From Chile, the Carmen 2017 Frida Kahlo Single Vineyard Cabernet Sauvignon is a big hit among our Vintage Wine Tasting Club. We have purchased plenty of this wine. My local Costco (Foster City) has a big supply. $9.99.

A wine I often purchase at Costco is the RUNQUIST RED BLEND 1448. The vintage currently in the Costco I frequent is 2017. This blend is consistently full bodied and fruit forward. A good all around table wine that, IMO, is a very good value. $12.99 at both Costco and the local Total Wine. Interestingly, I find no mention of this wine on the Jeff Runquist Winery website. Finally, I have had a number of other Runquist wines over the years and strongly recommend his Barbera.
Thank you, Tal for this wine recommendation. My Costco carried the Runquist for just short time. I have not seen it for several months. If I see it, I will give it a try. I have been to the tasting room in Amador. Lovely area! Joe
I liked the Lost Hog Sauvignon Blanc. Crisp, balanced, and has a hint of pineapple in the bouquet.
