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.

Pinot Noir from Morey-Saint-Denis, Côte-de-Nuits

Domaine Hubert Lignier Morey-Saint-Denis Grand Cru ‘Clos de la Roche’ 2018

Pinot Noir from Dezize-Lès-Maranges, Côte du Beaune

Domaine Bachelet-Monnot Maranges 1er Cru Clos de la Boutière Rouge 2022

“Blended with 30% whole bunches and from a massal selection made in the nineties, the 2022 Maranges Clos de la Boutière 1er Cru has a complex bouquet with blackberry, raspberry, iris flower and crushed stone aromas. This is very terroir-driven. The palate is medium-bodied with very fine tannins. It is elegant and harmonious, gently unfolding towards the finish with a sustained, slightly peppery aftertaste. A Maranges from the top drawer. Superb.”  Neal Martin, Vinous 92-94 points
