Blaufränkish/Lemberger
Blaufränkish/Lemberger Throughout Pennsylvania
The Blaufränkisch vine is known as an early budding variety that can be susceptible to early spring frost. It is a late ripening variety, and tends to be planted in warmer vineyard sites. Among the viticultural hazards that Blaufränkisch is most prone to are powdery and downy mildews. Blaufränkisch is considered a high productive vine capable of producing high yields fairly easily. In some parts of Europe it is not uncommon to see it harvested at 100 hectolitres per hectare (4,300 US quarts per acre). However over-cropping the vine has a tendency to produce thin wines with many green, weedy notes. Wikipedia
