Vilberie is a traditional French cider variety, producing a very tannic but sweet bittersweet juice.
The juice would normally be blended with juice from other varieties to produce a balanced cider.
Like a number of traditional English and French cider varieties, Vilberie is very late-blooming - in southern England or northern France it will typically flower in the last week of May. This can make cross-pollination an issue unless you have other late-flowering varieties available, although it seems to have reasonable self-fertility.
Vilberie is an old French variety, introduced to England in the late 19th century.
Cider production in Europe is traditionally associated with three main regions - Asturias in north west Spain, Bretagne and Normandie in north west France, and the "west country" area of south-west England. These regions all face the Atlantic ocean and have cool temperate maritime climates.
Cider can of course be made with any variety of apples, but in these three regions apple varieties have evolved which are specifically intended for cider production - they have high levels of tannins which give "body" to the resulting cider, but which make them very unpalatable to eat fresh.
Good quality cider is almost always made with a blend of different apple varieties, using bitter, sweet, and sharp flavour components. It is quite common to mix in regular cooking and dessert apples to lend extra flavours.
If you are in an area with a hotter continental climate (with average summer maximum temperatures routinely over 30C) then you might want to consider using apple varieties that can withstand warmer temperatures, but still have good juice qualities. In this case rather than using European varieties you might want to seek inspiration from the very different "hard cider" traditions of North America, where dessert and crab-apples are widely used.
We have a good range of traditional English and French cider varieties, as well as a number of mainstream apple varieties with good juice qualities that lend themselves to cider production.
