Glycerol is an alcohol produced by yeast during alcoholic fermentation of wine grapes. The amount produced depends on the yeast or mix of yeast fermenting the wine.

Glycerol production by yeast typically increases when they are under stress.

Glycerol main impact is on the mouthfeel and perceived weight of the wine. The mouthfeel tends to be a little more luscious and the perceived weight increases as the amount of glycerol increase.

The amount of glycerol in wine ranges from a few grams per litre, upto 10g/L in dry wine and as much as 20g/l in a sweet botrytis wine. That’s a fraction of the 120-150g/l of total alcohol.

Glycerol is the 3rd most-produced bi-product of fermentation after ethanol and carbon dioxide.

Tasting this in Apr 2024 it showed sophistication refinement of tannin, stunning flow and harmony. Deeply layered and delicious. A note differing to Guitiérrez' and perhaps a factor of being some 2 years older when tasted. Delicious.

This was a blend of 92% Tempranillo, 6% Graciano and 2% Garnacha from 30+-y

Jesus wept on the Bones of Saint Gratto! The very blood of Christ! As you step through the range each wine raises the bar. Hard not to devour now, Ridgey assures me these will last for decades. It’s times like this I wish it was easier to source an aged bottle or two! The 2018 Gattinara Riserva Osso San Grato is one of the great wines of the vintage. It offers notable depth married with a feeling of classicism that is palpable. Dark fruit, leather, spice, menthol, licorice, lavender
