Above all in the French Saint-Émilion (Bordeaux) in the 1990s created designation for special wines (french Vin de garage or also Vin de salon), which are produced in smallest quantities of often only a few hundred cases or few thousand bottles. These wineries are also called "Garagiste" or "Micro-Château" here, although not all of them are necessarily small. The term garage wine is not to be understood literally. It is derived from the computer industry, where from the 1970s onwards, small companies (such as Apple, Microsoft and INTEL) produced high-quality, innovative products in simply equipped premises and actually in garages. These were called "garage companies" and founded the boom in California's "Silicon Valley". Garage wines are characterized by the lowest yields from often very old vineyards, strictest manual selection of the highly ripe grapes, barrique maturation in 100% new barrique barrels and no or only gentle filtration. As a rule, these are full-bodied and alcohol-rich red wines of the highest quality, whereby the Cabernet Sauvignon and Merlot (also single-variety) grape varieties are frequently used.
