Abstract

Grape is a climbing plant that is from Vitaceae family and Vitis class and it is the oldest cultured fruit all over the world. The past of the grape goes to 3500 B.C. and homeland of grape is Anatolia. Grape is raw material at so many different food processes at Turkey.

Two of the most important consumers like criterias for must and so forth products are, bright red color and intensive aroma. In the case of must obtained with cold maceration from Kalecik Karasi vineyard, which has a strong aromatic structure and a particularly fruity aroma, a total of 30 volatile aromatic compounds, mainly 1-hexanol, benzeneethanol, benzeneacetaldehyde, limonene, trans-.beta.-Ionon-5,6-epoxide, 3-methyl-1-butanol, were determined.
