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.

There are three core parcels, all near the winery—the terraces directly surrounding the winery in Pinhão, the vines in the Roncão Valley and a parcel overlooking the Douro River. “The finish is long and jam-packed with delicious fruit, while the purity of that fruit is remarkable. Between its backbone and the freshness of the year, it should age well. Few will refuse a second glass of this debonair Porto at the

Late harvest quasi sforzato play here. There’s fun to be had here. ArPePe play in between a full-blown sforzato and the rest of their Riserva range makes for a fun balance. Completely dry, it introduces a level of richness and extra layer of tannin. Gary's note captures it well. Harvest is November 10th, because they leave the grapes to dry out and shrivel a little. It’s from the highest part of Sassella, sitting at 600m above sea level.  Cherry, blackberry, plum, dried mint,

A combination of three parcels throughout the famous Sanford & Benedict vineyard. Two of the plantings are 10-12 years old, but certainly responsible for the dark, deep core of this wine. The third piece, a small fermentation of the original, own-rooted plantings from 1971, brings the elegance and floral lift. Antonio Galloni, Vinous 94 Points
