The brands included three dry white wines, three semisweet white wines, and four dry red wines. The white and red bottled wines contained about 12% alcohol by volume. Aldehyde content of the wines differed among brands. The content of soluble solids in the wines showed a trend similar to that of reducing sugars. The total phenolics (tannin), as well as coloring matter content, decreased according to the age of the wines. Red wines contained higher amounts of polyphenolic compounds than white wines. %U https://www.ajevonline.org/content/ajev/31/2/165.full.pdf
