How does smoke taint impact wine?

Uptake and Release of Smoke Taint in Grapevines

When vineyards and grapes are exposed to smoke this can result in wines with undesirable sensory characters, such as smoky, burnt, ashy or medicinal, usually described as ‘smoke tainted’. The compounds in smoke often responsible for taint are largely free volatile phenols. The same phenols are produced when wood is burned, for example.

Sugars bind to these smoke compounds, so you can’t initially taste them and they don’t have a smoky aroma, but if the sugars break down, they may release the smoke compounds. These are glycosylated compounds. These compounds can be released into the wine or even the mouth while drinking the wine, causing the perception of a smoky flavor.

However, from the moment your wine hits the bottle to when it sells, smoke taint might not have an impact on your wine.

Despite all the worry around glycosylated compounds, it is uncertain that smoke taint compounds will express in the wine over time. Most retail wines are not designed to age and are typically consumed within a year. For such productions, the winemaker may consider the cost of various mitigation strategies against potential smoke effects over longer periods of time to be unwarranted.

Tastry’s Approach to Smoke Taint Analysis

A Few of the Compounds Tastry Measures
Guaiacol
4-Methylguaiacol
o-Cresol
m-Cresol
p-Cresol
Phenol

Since the majority of grocery store wines are consumed within a year after purchasing, Tastry takes a different approach that is designed for the typical winemaker that doesn’t involve measuring the glycosylated compounds in finished wines that may or may not be released from residual sugar breaking down years down the road. Instead, Tastry measures unbound smoke taint compounds post secondary fermentation.

Tastry goes beyond identifying concentrations of potentially problematic compounds. We give direction on how winemakers can lessen the impact of smoke taint through additions, blends, and changes that are specific to their needs.

TASTRY X PURFRESH

Purfresh Wine and Tastry Collaborate to Mitigate Smoke Taint

“The Purfresh Wine solution addresses the problem in the vineyard without impacting winemaking operations and is the only solution we have evaluated that provides additional benefits to the fruit beyond a meaningful reduction in smoke taint compounds.”
