It’s hard not to find appeal in the aromatics of a tropical fruit or floral Sauvignon Blanc or hints of vanilla, citrus, and caramel in a Chardonnay. But the road to get to those aromas takes vastly different paths. Alex Russan helps readers navigate the maze winemakers can take to maximize their white wine aromatics.
Volatile thiols are delicate but powerful aromatic compounds released during fermentation. Through careful techniques and yeast selection, these thiols can be both preserved and enhanced to create an aromatic wine that pleases the senses.
A Sadly, blending VA levels downward remains the only option available for reducing VA content in small lots. Larger commercial wineries, with big lots and bigger pocketbooks, can afford the expense of reverse osmosis and distillation technology to remove it from their wines but there’s no affordable option for small producers. Simple filtration doesn’t work
Many wine writers draw a distinction between “aroma” and “bouquet.” Typical is the discussion by Yair Margalit in his excellent book Concepts in Wine Chemistry. He says aroma “is the term for smell derived from the grape . . . Some varietal aromas are very powerful and recognized easily, and others are very weak and
Viognier can be a bit of an odd duck. Like Riesling, it can get some of those weird petrol/gas like aromas, and that’s just natural, from the grapes. Like Sauvignon Blanc, it
Did you ever create a wine that seemed more viscous than your typical wine, or which may have exhibited heavier fruity odors, or perhaps a solvent-like smell? The culprits may well be higher alcohols, also called fusel oils; all wines contain some at various concentrations. Higher alcohols in small concentrations can contribute positive aromatic characteristics
If you are of the opinion that yeast selection does not matter and that the only role of yeast is to convert sugar into ethyl alcohol (ethanol), you may have been missing
Getting and keeping attractive aromatics is a major goal of winemaking, home or commercial, and it isn’t easy. It is a goal and a concern at every step along the way, from harvest to bottle aging; it’s not something you do all at once, like tannin extraction during fermentation. The aromatic calculus for whites differs
