Since antiquity, the area of Thrace, along with that of Macedonia, has been a focal point of the Dionysian cult, making it no coincidence that the god Dionysus is believed to have come from this area. In modern times, however, there has been a shift towards other, more profitable kinds of crops, such as tobacco, leading to the shrinking and eventual abandonment of vineyards. As recently as the last few decades, the situation has changed to the benefit of viticulture.
The climate is humid and warm with high rainfall, particularly during the summer. The Rodopi Mountain Range protects the vineyards against the cold northern winds and its proximity to the northern Aegean Sea mitigates the low winter temperatures and ensures cooler ones in summertime. The grapes grown in Thrace are a mixture of international and local cultivars.
As far as the coastal regions are concerned, viticulture is favoured only in a small patch of land extending from just after the city of Kavala up to Maroneia, where the levels of rainfalls, especially in the summer, are normal. In Maroneia, just four kilometres from the seaside and close to Mt. Ismaros, the vineyards are located at an altitude of roughly 350m (1150 ft) and at a lower temperatures compared to those at sea-level, thus producing wines of higher acidity and better levels of colour. Avdira is another important wine-producing area of Thrace and bears many similarities to Maroneia with regard both to its climate and morphology.
