A method for preparing a grape skin powder and for preserving volatile thiol precursors in the grape skin powder, the method comprising:
- (i) obtaining skin and seeds of white wine grapes having flesh and juice components of the white wine grapes substantially removed,
- (ii) directly freezing the skin and seeds of the white wine grapes,
- (iii) thawing the skin and seeds of the white wine grapes from step (ii) to a pliable state, wherein the thawing is carried out over at least 24 hours,
- and
- (iv) drying the thawed skin and seeds of the white wine grapes from step (iii) to produce the grape skin powder, wherein the grape skin powder contains at least one volatile thiol precursor at levels of at least 5,000 ng/kg.

A method of making a fermented beverage, comprising:
- preparing a mixture comprising yeast, liquid, and composition comprising a grape skin powder, wherein the grape skin powder is prepared
- by a method that preserves volatile thiol precursors in the grape skin powder, the method comprising:
- (i) obtaining skin and seeds of white wine grapes having flesh and juice components of the white wine grapes substantially removed,
- (ii) directly freezing the skin and seeds of the white wine grapes,
- (iii) thawing the skin and seeds of the white wine grapes from step (ii) to a pliable state, wherein the thawing is carried out over at least 24 hours,
- and
- (iv) drying the thawed skin and seeds of the white wine grapes from step (iii) to produce the grape skin powder, wherein the grape skin powder contains at least one volatile thiol precursor at levels of at least 5.000 ng/kg,
- and
- fermenting the mixture to obtain the fermented beverage.
