Almost all of them. Only few varieties are hybrid or manually breeded. Out of those 500+ varieties, around 50 are in production. The rest are either very rare to find, are grown in a small quantities or are kept in the vine nurseries as a collection varieties. Saperavi (red) and Rkatsiteli (white) are amongst the most popular, though there are other ones that are really good: Mtsvane, Chinuri, Kisi, Tsitska, Aleksandrouli, Shavkapito and my personal favourite - Usakhelauri (once I opened a bottle at home and within a hour aromas were spread across the whole house like a premium fragrance).
