Wine — Winemaking: Vine to Wine

Viticulture, the process of maturation wine grapes, has been raised from ancient art to a complex combining of science and art. Add in all the other special cognition and skills required to produce the end yieldbottled wine and you have a Herculean (or is that Dionysian?) task.

Vintners, makers of wine, have to consider site, season, soil and a host of other factors in order to surrender fine wine to the consumer’s table.

Dark soils occupy heat more efficiently and unsmooth soils allow better drain and provide stones that also help retain heat. Relative concentrations of nitrogen and other elements play an essential part. Topography (the contours of land) partly determine the usable amounts of sunlight and shade, while climate encompasses temperature range, total sunlight uncommitted, annual rain, wind and so forth.

Which grapes are selected to be grown depend on the terroir. A ‘terroir’ is a group of vineyards (or even vines) from the same region that share similar soil type, weather conditions and other attributes. Planting time varies from late March to early April, with harvest ranging from late September to early October, depending on location, species and human judgment.

Once harvested, usually by hand, the grapes are off to the crusher to be turned into must – skin, meat, and juice created in large vats containing a perforated, rotating drum. The holes allow juice and skins to pass through, but filter out stems.

Red-grape must is then sent to fermenting tanks, while white goes first to a wine press. The press is a large, usually stainless-steel cylindrical tank with an inflatable rubber bladder inside. The bladder is used to press the skins against the tank walls to separate them from the juice. The solvent is sent to another fermentation tank.

Airtight fermentation tanks, retention anywhere from 1,500-3,000 gallons are cooled to nearly 40F (4C) and the vintner adds sugar and yeast to initiate the process. The yeast interacts with the glucose in the must through diffusion and a process called glycolysis occurs which produces other sugars and alcohol. This takes roughly 2-4 weeks, during which the vintner samples and measures the mixture.

Once fermentation is realized, red wines are sent to a press to filter the skins from what is now wine, then filtered again to remove the yeast. Some reds undergo a second, malolactic, fermentation process. White wines, by contrast, are allowed to settle, after which the yeast is filtered out.

With the yeast removed, the wines are stored in stainless steel tanks or oak barrels for anywhere between 3?months and three years.

After sufficient ripening, where ‘sufficient’ is determined by individual judgment based on repeated judge and other tests, the wine is pumped from the tanks to a bottling machine. Most vineyards now have a exceedingly automated bottling process, though even there labeling, foil addition, and stacking is often still done by hand.

Despite the many modern improvements to the winemaking process, most growers and winemakers still take a personal and passionate interest in selecting and tending vines, creating delightful varieties, and judging whether product meets their high standards. It’s easy to taste the results.
