what is rs in wine
This wine has a little RS, and that's cool by me.... In the interest of a tolerant spirit, let's explore the whys and the how-comes. Residual Sugar, or RS for short, refers to any natural grape sugars that are leftover after fermentation ceases (whether on purpose or not).The juice of wine grapes starts out intensely sweet, and fermentation uses up that sugar as the yeasts feast upon it. winemaker can chill a wine down until fermentation stops, then just get rid of the yeast. No more yeast, no more fermentation. Certain chemical compounds can snuff them out, too. In addition to its obvious sweetening power, sugar also has a bonus effect: it can help wines age well.
