22/09/2020 What do your Residual Sugar (RS) levels mean, and how they help you in wine tasting.

Sommelier Business joins with Nicolas Quillé, MW to create a short wine technical series to give on-trade professionals wine technical knowledge. In this article we write about Estimating Residual Sugar

Estimating residual sugar (RS) helps during wine tasting. Discovering how the wine got sweet will help identification:

1. Arrested fermentation: grapes picked between 10 and 14% potential ABV and fermentation stopped before dryness. Clues are lower ABV than its potential ABV, solid acidity & high level of focused primary and secondary aromatics.

2. Fortification: grapes picked at moderate sugar levels & added high proof stops the fermentation. Clues are a high level of RS & the high ABV is matched by a solid acidity.

3. Concentration of grapes to a high potential ABV before fermentation (14 to 35%) using:

a. Cryoextraction: Frozen grapes are pressed concentrating the juice. Freezing may occur in the field (true icewine) or in a freezing chamber. Clues are elevated acidity, intense focused fruit, high RS. Freezing chamber leads to purest styles. True icewine are more complex (layers from dehydration and botrytis)

b. Dehydration: from late harvest or by disconnecting the cluster from the plant and drying. Clues are high RS, moderate to low acidity, moderate alcohols, distinctive raisin aromatics, sometime VA.

c. Botrytis: dehydration through the intervention of noble rot. Clues are elevated RS, high viscosity (glycerol), low acidity, moderate alcohols and ginger/honey aromatics.
