I was at Bevmo a couple days ago and found Castellane Brut Non-vintage for $19.99 (usually $24.99). I thought this was a really good deal for a couple of reasons -
1. There just aren't many champagnes (as opposed to sparkling wines) available in the San Francisco Bay Area for under $20
2. The Castellane Brut is a good, solid champange. Its crisp and lovely, not too yeasty, not too sweet.
We liked pretty much everything we had at Castellane's tasting room in Epernay a few years ago and we very sad to learn they didn't export to the States. We brought back a number of bottles from our trip but finished our last bottle about six months ago so coming across bottles locally was great! I suspect the reason for the good price is that its not a well-known brand in the US (where most of the population buys known brands like Veuve & Dom).
I love finding lesser known brands that perform as well as "designer labels". Does anyone know of similar deals/finds?
