Read the previous part. ← How to choose the right grape variety

All varieties, which I will name below, hibernate under a cover of spruce branches or dry foliage, on top of which a small layer of earth is poured (about 5 cm).

The ripening dates of the crops and vines given below were observed in an unheated glass greenhouse during 1977-1986. The main requirement for varieties for film greenhouses is not very strong growth of shoots and the absence of cracking of berries in greenhouse conditions, where the humidity, as you know, is much higher than outside.
