- Süssreserve
Süssreserve (German: Süßreserve, literally meaning "sweet reserve") is a
wine term referring to a portion of selected unfermented grapemust , free of microorganisms, to be added to wine as a sweeting component. This technique was developed inGermany and is used with German style wines such as semi-sweetRiesling orMüller-Thurgau . [ [http://www.winepressnw.com/features/story/4842844p-4779998c.html Wine Press Northwest] ] The technique not only raises the sugar level of the wine, but also lowers the amount of alcohol. Under German law, no more than fifteen percent of the final wine's volume may be the reserved juice. [ [http://www.epicurious.com/drinking/wine_dictionary/entry?id=8131 The Wine Dictionary] ] This practice is allowed also forPrädikatswein , the highest level in theGerman wine classification . It is often used for semi-sweetKabinett andSpätlese but more rarely forAuslese and upward.The use of Süssreserve gives a different composition of sugars in the wine in comparison to arrested fermentation. Grape must contains mainly the sugars
glucose andfructose . When wine ferments, glucose is fermented at a higher rate than fructose. Thus, arresting fermentation when a significant portions of the sugars have fermented gives a wine where the residual sugar consists mainly of fructose, while the use of Süssreserve will give a wine where the sweetness comes from a mixture of glucose and fructose.ee also
