Suitability for cultivation and agronomic production

Glera is vigorous and has a drooping bearing. It is usually pruned long to increase the yields and needs to be well trellised. This variety provides sufficient and regular yields and its ramifications are not very fertile. As its bud burst is early, Glera is sensitive to sping frosts. It is susceptible to coulure, millerandage and drought.
Susceptibility to diseases and pests

Glera is sensitive to downy mildew, powdery mildew and phytoplasmas (flavescence dorée).
Technological potentiality

Glera's bunches are medium to large in size and not very compact. The berries are medium in size, with a simple flavor, a thin skin and a juicy pulp. This variety gives mostly sparkling wines of the "spumante" or "frizzante" style, with a low alcohol degree and a good acidity. Glera can also be used to produce light-bodied, rather lively and harmonious in the mouth dry white wines.
Clonal selection in France

The only certified Glera clone carries the number 1317.
