Analysis Brings Certainty

The age-old belief states: "A glass of red wine in the evening promotes health." But not all red wines are the same.
As W&G Wine & Health laboratory analyses show, the phenol content among tested red wines can vary up to fivefold.
W&G has now examined whether there is a connection between a wine’s appearance and characteristics and its phenol content.
Findings suggest that wines with higher alcohol content and darker color tend to have higher phenol concentrations than so-called light, thin wines.
One explanation is that marmalade-like wines achieve higher phenol concentration due to juice extraction during winemaking.
For wines with 14% alcohol or more, concentration often begins in the vineyard—the water in the berries evaporates naturally during ripening.
However, only laboratory analysis provides certainty—and often leads to surprising results.
