The principle of winemaking is one of the oldest chemistry experiments of all time! While the formula remains the same, the winemaker, or Vintner, is the master creator and influencer throughout the winemaking process. His or her decisions influence what you see, smell or taste when you open a bottle of wine and pour it into a glass.
In order to understand what happens in the process and how such different results can be achieved, let’s break it down to a few basics. Grapes come in all shapes, sizes and colors, but they all have skin, pulp, pits and stems. Pulp from every type of grape contains sugar and water and is always pale in color. Grape skins vary from pale yellows and greens to deep reds and purples. It is from the skin that rosé and red wines get their color. Skins also provide tannins to red wines during the winemaking process. Stems and pits also can impact wines, but we will focus our attention on grape pulp and skin.
