Merkin Vineyards, established in the high-altitude desert regions of Arizona, sources Tempranillo and Garnacha grapes adapted to the region's demanding climate. The vineyard benefits from dramatic diurnal temperature variations characteristic of Arizona's semi-arid terroir, where daytime heat is moderated by cool evening conditions. These conditions allow for extended ripening periods that concentrate fruit flavours whilst preserving natural acidity. The house follows sustainable viticulture practices suited to water conservation in the desert environment, with vintage conditions varying from year to year based on seasonal rainfall patterns typical of the American Southwest. NEEDS VERIFICATION: Specific vineyard locations and organic/sustainable certification details.

The Tempranillo and Garnacha blend is harvested by hand at optimal ripeness to preserve varietal character. Fermentation takes place in temperature-controlled stainless steel tanks to extract colour and tannin structure whilst maintaining freshness. The wines undergo a moderate oak programme with a blend of French and American oak to balance structure with the fruit-forward profile characteristic of the blend. Malolactic fermentation occurs post-primary fermentation to soften acidity and add textural complexity. The final blend balances the structured tannins of Tempranillo with the softer, spice-driven character of Garnacha. NEEDS VERIFICATION: Specific fermentation duration, oak aging period, and percentage composition of the blend.
