The Land
Argentina is Malbec country in most people's minds, but this is a white, and an old one at that. The grapes come from the Uco Valley, the high, cool heart of Mendoza, set against the Andes at the western edge of the region. Vineyards here sit well above 1,000 meters, where intense mountain sunlight ripens the fruit while cold nights lock in acidity. The Semillon grows in the Tupungato district on soils of clay, loam, and sand, from vines planted roughly a century ago, back when Semillon was one of Argentina's most widely planted whites, before Malbec took over. Altitude and old roots are what give this wine its tension and depth.
The Wine
100% Semillon from century-old vines, made with a natural, low-intervention hand. Fermentation runs on native yeasts in concrete, and the wine spends about two years in large 500-liter French oak barrels, which builds texture without stamping on the fruit. Expect quince, pear, apricot, and lemon, with marmalade and a savory, biscuit-like depth from the long aging, all carried on a textured, saline frame. The 2023 vintage was tiny: hard spring frosts across Mendoza cut yields to their lowest in decades, but the warm, dry summer that followed left clean fruit with unusually high acidity, which suits this style. Around 12.5% alcohol. A serious, age-worthy white.
The People
Escala Humana was founded in 2015 by Germán Masera and his wife Ayelén. Germán trained in enology and viticulture in Mendoza, began making wine in 2003, and has worked alongside Matías Michelini since 2016. The project has a clear mission: to rescue and revive Argentina's overlooked historical grape varieties and old vineyards in the Uco Valley, working naturally and parcel by parcel. The name translates as "human scale," and the wines are made in small quantities with native yeasts and minimal additions. Credo, meaning a statement of belief, is the label Masera reserves for the wines meant to express their site most fully.
Food Pairing
Old-vine Semillon with oak and age wants richer food. Pour it with roast pork loin, chicken in a cream and mushroom sauce, grilled trout with brown butter, or a plate of hard alpine cheeses. The weight and texture stand up to fat and richness while the acidity keeps the palate fresh, and the savory, marmalade side pairs well with anything roasted or browned. Serve cool, not cold, and give it a little air.
