 "Barrels made of American white oak are commonly used for oak aging of wine, in which the wood is noted for imparting strong flavors. Also, by federal regulation, bourbon whiskey must be aged in charred new oak (generally understood to mean specifically American white oak) barrels." [[https://en.wikipedia.org/wiki/Quercus_alba]]
+„…methylene chloride extracts of various experimental beverage brandies, unaged and aged in French and American oak barrels, were analyzed for higher boiling volatile compounds by temperature-programmed gas chromatography. Diethyl succinate, 5-methyl furfural, and β-methyl-γ-octalactone were identified as substances derived from oak during aging. These compounds were found in relatively high concentrations in brandies aged in American (U.S.) oak.“ \\
