- low yielding
- high color
- high tannin
- concentrated flavors
- finest grape but occupies little vineyard plantings
- when phyloxerra hit, this suffered because of it's low yield property and lack of good rootstock availability, increased it's probability of poor fruit set.
- almost extint by the late 70's
- clonal selection helped w/ it's comeback in the 1980's grown in Cima Corgo and Douro Superior
- it's high vigor and is succeltible to cool, damp weather during flowering
- Cockburns said to have the greatest number of plantings
- easily over ripens
- small and thick skinned berries
- produces the most concentrated of wines
- capable of high alc levels
- distinctive floral aromas, violets and bergamot
- essential in all of the vintage ports
- again, yields are variable, too high alt not good for it either (like douro superior - best at Cima Corgo)
- prone to coulure
- make it unpopular for growers
- know as a winemakers grape than a growers grape
- deep color
- naturally unproductive but high vigor
- pain to manage in the vineyard
- best of all port grapes
- clonal selection is key
- has tiny berries
- succeptible to coulure
- ripens early
- produces black wines with high aromatics
- great extract and high tannin
- prefers hotter situations
- poor pollinator so yields are naturally low
- vine is highly vigorous though (hence the battle for which gets the nutrients)
- goal is to increase plantings and increase sugar content overall for quality purposes
- best clone selection now is R110
