WINEGROWING
Vitis
vinifera can only be cultivated in climate zones where the
average yearly temperature is between 14 and 15 °C (57.2 -
59 °F) (ideally) and cannot grow, much less produce
quality wine in areas with a yearly average below 10 °C
(50 °F). These climatic conditions are only achieved
between 30 °N and 50 °N in the northern hemisphere
and 30 °S and 50 °S in the southern hemisphere, and
even there only in regions where the summer heat is moderated by
proximity to the sea or other large bodies of water. The vine
may grow closer to the equator, but the resulting grape would
only accumulate abundant sugar and pigments with aromatics and
acids too scarce for production of quality wine. Further north
and south, the temperatures are simply too low, the summers too
short, and the spring frosts too severe for the gentle shoots.

Slovenia
lies in an ideal climate zone: between 45 ° 30'N and 47 °N,
with the Adriatic Sea as a part of its western border. The Alps
form Slovenia's northern border - these shield the land from the
harshest of northern weather and also moderate the intense
continental summer heat. The southern slopes of the Alps and
their rolling foothills offer a large number of good
viticultural sites that are grouped into three viticultural
regions differing in microclimate, soil composition and
viticultural tradition: Podravje,
Posavje,
and Primorje.
With such a wide variety of ampelographic conditions, Slovene
viticulturists have been able apply and customize vines,
winegrowing, and methods of making wine from all parts of
Europe. The taste and bouquet of Slovene wines range from heavy
Bordeaux-style blended red wines to the aromatic white wines of
the Mosel and Rhine valleys, from the dry wines of Italy to the
sweet varieties offered by Hungary, from the heavy port and
sherry of Spain and Portugal to the light and subtle wines of
Champagne and Alsace-Lorraine. A number of local varieties grown
nowhere else have also been developed during Slovenia's long
viticultural history.
In
general, the viticultural sites of Slovenia are particularly
suited to production of quality
and high-quality
wines. The slopes are generally quite steep, which guarantees
optimal sunshine but makes cultivation difficult and
labour-intensive and the yield less than optimal. Slovene
vineyards are planted with relatively old vines, some 7000
hectares (17,297 acres) - 32.4% of all vineyards - grow vines
over twenty years old; only some 1200 hectares (2965 acres) -
5.6% - are "young" vineyards (with vines under four
years old).
