Luna Rossa Winery
3710 W Pine St
(http://www.lunarossawinery.com) is visible from the highway on the frontage road going into town on i-10 eastbound.
Two wineries, yes, two wineries are present in this desert landscape. Neither one charges for tasting and both charge reasonable prices for their wine.
St. Clair Vineyards
(http://www.stclairvineyar...) is a larger operation than luna rossa. there are signs in town directing you to the vineyard. warning: their website blasts annoying music.
