Wine enthusiasts are occasionally given to talking about "desert island" wines, usually in the form of which region they would choose if limited to one.
That's a decidedly different notion from "desert" wines, which might seem like an oxymoron given that grapes (or most anything) cannot grow in pure, inert sand.
Turns out, though, that most classical wine grapes originated in the desert-laden Middle East, according to research and genetic testing at the University of California, Davis.
Since then, grapevines have thrived in arid climates — rain-free harvest seasons are a particular plus — and stellar wines have popped up in unexpected places.
Like Arizona, New Mexico and now Baja California.
In the first two cases, we're talking high desert. At its elevation, the huge swing in temperatures from day to night helps grapes retain acidity and not produce flabby wines.
Arizona actually has 121 vineyards, but little of its wine reaches us. What does — red blends from wineries such as Caduceus and Dos Cabezas — is worth checking out but won't fit the budgets of those who stay under $20 with their wine purchases.
Neighboring New Mexico, on the other hand, is a veritable font of bargain bottles in the bubbly bailiwick. Domaine Saint Vincent's sparkling wines are simple pleasures for around $15, while Gruet's offerings, most in the same price range, are killer bargains.
