In Canada, red wine dominates with a 52.3% share of total wine sales in 2004, although there are regional disparities, with Quebec favoring it even more. [13] In the United States, there is a balance between white wine, preferred by women, and red wine, favored by men. [8] Red wine is gaining market share in many countries.
A glass of red wine. The health effects of wine are mainly determined by its active ingredient – alcohol. [1] [2] Preliminary studies found that drinking small quantities of wine (up to one standard drink per day for women and one to two drinks per day for men), particularly of red wine, may be associated with a decreased risk of cardiovascular diseases, cognitive decline, stroke, diabetes ...
Dipak Kumar Das (1947 – September 19, 2013) [1] was the director of the Cardiovascular Research Center at the University of Connecticut Health Center in Farmington and is known for research fraud. His work centered on the beneficial properties of resveratrol , which is found in red wine , [ 2 ] but over twenty of his research papers have been ...
Red wine contains between 0.2 and 5.8 mg/L, depending on the grape variety. White wine has much less because red wine is fermented with the skins, allowing the wine to extract the resveratrol, whereas white wine is fermented after the skin has been removed. [6]
A rosé wine gains color from red grape skins, but not enough to qualify it as a red wine. It may be the oldest known type of wine, as it is the most straightforward to make with the skin contact method. The color can range from a pale orange to a vivid near-purple, depending on the varietals used and wine-making techniques.
Orange wine (a.k.a. skin-contact white wine) is wine made with maceration in the manner of rosé or red wine production, but using white wine grape varieties instead of red.
