Luminara Alcohol-Removed Chardonnay. Luminara. TOTAL: 93/100. Served side-by-side with a glass of classic chardonnay, our taster was stumped: Which had 12.5 percent ABV, and which was less than 0. ...
The aroma compounds are then mixed back into the wine. Some producers such as Joel Peterson of Ravenswood argue that technological "fixes" such as spinning cones remove a sense of terroir from the wine; if the wine has the tannins and other components to balance 15% alcohol, Peterson argues that it should be accepted on its own terms.

Large pectin molecules can affect the amount of juice yielded at pressing, ease of filtration and clarification, and extraction of tannins. Grapes contain natural pectolytic enzymes responsible for softening the grape berries during ripening, but these are not active under wine-making conditions (due to pH level, SO 2, and alcohol.) Therefore ...
Esters: [2] Ethyl acetate is the most common ester in wine, being the product of the most common volatile organic acid — acetic acid, and the ethyl alcohol generated during the fermentation. Norisoprenoids, such as C13-norisoprenoids found in grape (Vitis vinifera) [8] or wine, [9] can be produced by fungal peroxidases [10] or glycosidases. [11]
[2] [3] The practice of leaving a wine to age on its lees (or sur lie aging) has a long history in winemaking dating back to Roman winemaking. The chemical process and details of autolysis were not originally understood scientifically, but the positive effects such as a creamy mouthfeel, breadlike and floral aromas, and reduced astringency were ...
1/2 c. reduced-sodium soy sauce ... 1/4 c. rice wine vinegar. 3 tbsp. packed light brown sugar ... 1 lb. flank steak, thinly sliced against the grain. 1. green bell pepper, seeds and ribs removed ...
Some wine journalists contend that chaptalization allows wine makers to sacrifice quality in favor of quantity by letting vines overproduce high yields of grapes that have not fully ripened. [9] Also, winemakers have been using technological advances, such as reverse osmosis to remove water from the unfermented grape juice, thereby increasing ...
Not all sugars are fermentable, with sugars like the five-carbon arabinose, rhamnose and xylose still being present in the wine after fermentation. Very high sugar content will effectively kill the yeast once a certain (high) alcohol content is reached. For these reasons, no wine is ever fermented completely "dry" (meaning without any residual ...
