(d) East Anatolia (12 red wines).climate with average temperatures of 9C in winter and 29C in summer.

The average temperature is 23C in summer and -2C in winter. Theclimate in the Black Sea region is wet, warm and humid (summer is 23C andwinter is 7C). In the Eastern Anatolia and Southeastern Anatolia regions, thereis a long, hard winter where year after year the snow lies on the ground fromNovember until the end of April (the average temperature in winter is -13Cand in summer is 17C) (Fig. 6).The first experiments on the OTA levels of Turkish wines were done inthe Direction Générale du Crédit et des Relations Financières laboratory(Bordeaux, France) in 1999 by analyzing 16 red wines from Turkey; thesevalues prompted us to repeat this research and use more wine samples.
