Q

Socalcos

A

Traditional vineyard layout
Narrow terraces supported by dry rock walls
6,000 vines/hectare
Not suitable for machine (+ labour to maintain)
Not considered for new vyds
Protected by UNESCO; cannot be converted

Q

Patamares

A

Terraces supported by steep earth ramp (not stone wall)
Small tractors up/down slopes - tracks run diagnolly
Cheaper to implement and maintain than Socalcos
Problems: erosion nd weeds
3,000-3,500 vines/hea

Two kinds: large, wide (two rows of vines) vs. narrow (one row)

Wide version is the original, constructed when bulldozers were large and bulky
Narrow ones newer - new technology

Use is limited (water runoff and erosion a problem)

“Beneficio” means the system AND the amount

97
Q

How are vineyards rated for Port production?

A

Each parcel classified for its capacity to produce quality grapes
Location, altitude, aspect, soil and grape varieties
Parcel receives a numerical value for each factor
Final total used to give parcel a letter (A to I)

98
Q

What letter indicates vineyards of highest quality in Port?

A

A

Highest quality ranking = allowed to produce the most Port

99
Q

Vineyards rated below F can make Port wine. T/F?

A

False

They can make unfortified wine or distilled into spirits

100
Q

How is amount of Port must (ie Beneficio) decided?

A

Different quantity every year
Agreed between growers, producers and IVDP
Considers: market demand, current stocks available in market

Aim: keep grapea dn wine prices stable by balancing supply and demand

101
Q

Why is Beneficio unpopular with producers/growers?

A

Demand overall has declined
Volume of Port allowed to be produced is reduced BUT
land under vine expanded, unfortified wine permitted
oversupply of grapes for unfortified Douro
prices not fixed by Benefico = very low prices

Port producers feel they are subsidising the industry for unfortified Douro wines by paying artificially high prices for Port grapse

102
