If Champagne is the ultimate snob wine, then here is my candidate for the ultimate reverse snobbery.
Maybe you should sit down first.
The best under $20 bottle of bubbly is a real Champagne. And it is the Kirkland Brut sold at every Costco. It is authentic is every detail…grape varieties, bottled within the region, and, yes, taste.
Sorry snobs, but it truly smells and tastes like Champagne with persistent, tiny bubbles, yeasty overtones and good balance, The most remarkable thing is that it displays Champagne’s typical yeast aged complexity.
There is no Cava and especially no Prosecco that comes close. You will likely find more fruit in California bubbly priced below $20, but not the typical and lovely Champagne character.
Try it over the holidays.
