Phenylethyl- a- D -glucopyranoside

The role of these glycoconjugates in the formation of important wine aroma volatiles is discussed. In addition, the identification of uncommon glycoconjugates in Riesling wine is reported. These novel wine constituents include 2-phenylethyl-a-D-glucopyranoside, the N-glucoside of 2-ethyl-3-methylmaleimide as well as the Ji-D-glucose ester of 10,11-di-hydroxy-3,7,1 l-trimethyl-2,6-dodecadienoic acid.
