Red wine can take several years to smooth out but is usually worth the wait. Sometimes a wine can remain a little harsh if the tannin is very high or the acid is high. These harsh wines can have a relatively poor mouth feel and a short finish. They may never reach their full potential without a little nudge from glycerol. Glycerol, also known as glycerine or glycerin is naturally produced in the yeast cell during active fermentation. It helps to balance out the osmotic pressure that occurs when the juice or must is at higher sugar levels. By itself, glycerol is odorless and relatively sweet with a high viscosity. As the glycerol levels increase in the wine, the mouth feel improves. A subtle change in glycerol content might be difficult to detect but at additions of about two to four grams per liter it becomes very evident that the mouth feel is better. In this video we will talk about how to naturally encourage higher glycerol levels and also how to add it later on in the process.
