Addition of dry sugar such as beet sugar (granulated sugar) or sucrose to grapes, grape must, partially fermented grape must or young wine for the purpose of increasing alcohol. A sugar dissolver (container with homogeniser) is used for this purpose. The common term for dry sugaring is enrichment, and in some countries colloquially also chaptalisation. In contrast to this is the addition of sugar to the finished wine in order to increase the residual sugar content. See sweetening with regard to wine regulations within the EU.

There is a vast number of sources on the web where one can acquire knowledge about wine. But none has the scope, timeliness and accuracy of the information in the encyclopaedia at wein.plus. I use it regularly and rely on it.
