Edetària: Benchmark wines of Catalonia’s Terra Alta DO

Terra Alta is the most westerly of Catalonia’s DOs which are clustered around Barcelona and include Alella, Conca de Barberá, Costers del Segre, Empordà (on the border of France), Montsant, Penedés, Plà de Bagés, Priorat (DOPQ) and Tarragona. Both Cataluña and Cava are broader designations that also apply to the Catalonia region.

Minerality — Without question the most controversial and elusive of wine descriptors.   This comes as no surprise given that the exact definition of what minerals themselves are is still under debate and has been expanded as an element or compound formed through “biogeochemical” processes.  Nutrient or dietary minerals—single elements like manganese, potassium, magnesium, iron, phosphorus, calcium, copper and zinc—are minor components of red wine. White wines have small amounts of iron, calcium, potassium, phosphorus and zinc. A serving of wine can also contain several milligrams of halite, the mineral salt (sodium chloride is the chemical name for salt), and we can accurately describe its taste in wine as saline minerality. Knowing that wine contains minerals, why is describing minerality so problematic?  Largely because aside from halite, nutrient minerals are essentially tasteless. Only when they’re in a highly concentrated liquid form, for example as a dietary supplement, do they taste offensively bitter. But the elusive flavors we describe as “mineral” in some wines can be readily attributed to specific compounds. The two of the most common …

Flash Heat Treatment Shown to Benefit Vines and Wine

Many advances pioneered by the dairy industry have improved winemaking in the cellar, but when it comes to using flash or instantaneous heat, it all starts in the vineyard. Flash pasteurization was first applied to milk in 1933. Sixty years later, flashbake ovens made their debut and, shortly thereafter, the adoption of frost prevention and thermal pest control techniques for winegrowing began making news. Fast forward two decades and you’ll find the latest generation of Thermal Plant Treatment (TPT) technology gaining interest from Oregon to Monterey. After three years of rigorous trials by Walnut Creek, Calif.-based AgroThermal Systems, trials show that patented flash heat treatments to vines are producing a host of benefits that extend well beyond the disruption of pest lifecycles.

Going to Extremes

On the first day of spring in the Southern Hemisphere, a cold, dry Zonda or rain shadow wind swept down the eastern slopes of the Andes and dropped a blanket of snow over the vineyards of Mendoza, Argentina. “It’s a beautiful sight but devastating to budding vines and fruit trees when followed by a frost,” said Andrés Rosberg, President of the Association of Argentine Sommeliers. Early-budding Chardonnay (and the stone fruit trees) in the Valle de Uco and San Rafael suffered this vintage, but frost and hail storms are the exceptions in Mendoza, where wine-growing conditions are considered less than extreme. Argentina’s most rigorous wine-growing conditions are found at the country’s extremes: from remote 10,000-foot sites in Salta to the north and the cold, arid steppes of Patagonia to the south. But the country’s wine culture traces its roots to more hospitable sites. Vines first arrived in the northern province of Santiago del Estero and were brought from Chile to the San Juan and Mendoza regions in the mid-16th century. The arrival of European immigrants …

Soil Survey: a crossword puzzle for the terroir obessed

Dirt.  It’s the first thing that comes to mind when I think about the influence of terroir and its contribution to the flavor in wine is one of the most controversial and debated topics among wine enthusiasts.  I created this crossword puzzle to help my WSET Level 3 students study soil types in a creative way.  Even if you’re not a student of wine you’ve probably already encountered many of the soils I’ve included here.  So, put on your geological thinking cap and have at it with these clues Soil Survey Clues. You’ll can find the answers here. Soil Survey Answer Key
