Winemaking originated as a form of self-defense against prehistoric saber-toothed grapes. Ferment away your fears with today's Groupon: for $20, you get a Cellar Masters Wine Club membership (a $75 value) from Wineries Group LLC.

The winemeisters behind the vintages of Retro and Scoundrel offer a Wonka-esque peek at the esoteric alchemy underlying their locally bottled libations. With a Cellar Masters Wine Club membership, vintophiles receive free ground shipping and a 50% discount on all purchases (including tasting room and online buys), along with preferential notice on new releases, members-only tastings, wine dinners, cork beauty pageants, and special events hosted at the winery or across the country. Membership also includes the quarterly newsletter Wine-a-cation, with regular features on winery news and upcoming events as well as pro tips for wine tasting and making. An innovative points program rewards members for referrals and more, redeemable for gift cards, exclusive reservations on promotional trips and in-cask events, and annual drawings for wine tours.

Wineries Group is in the design stages of an ambitiously green winery that will abandon the traditional source of vintner power, coal-powered grape-stompers, for wind, solar, and geothermal energy. Historically, El Paso was once known as a premier wine region that, in the 1700s, produced wines specifically for the king and queen of Spain. Wineries Group strives now to recapture that heritage, crafting grown-up grape drinks capable of pleasing modern-day royalty and democratically elected dogcatchers alike.
