VITICULTURAL HISTORY

Vine and wine have been

constant for millennia in the

territory that is now Portugal.

This economic and cultural

inheritance was bequeathed by

people from the Mediterranean

basin and from the 6th century

BCE onwards; Phoenicians,

Greeks, Jews and Romans left

in this area their practices and

techniques, technologies, sets

of dishes, and customs as well

as grape cultivars. In a second

period dating from the Moorish

conquest of Iberia in the 8th

century another legacy of grape

growing was bequeathed. Arab

viticulture was enhanced with

new grapes, more for table use

or raisins than for the production

of wine or vinegar, although

vinegar was regularly produced

and very appreciated in

cookery. In the medieval period

during the origin of national

identity, a third acculturation

period occurred. The Roman

Catholic mass, based on the

rite of the Eucharist and the

transubstantiation of wine into

the blood of Christ, was the

original stimulus to medieval

grape-growing that spread

the culture of the vine and led

to abundant consumption

and commerce. Cistercian

friars coming from Burgundy

brought in an original way

to cultivate the vine and to

make the wine. Other religious

orders helped to spread

grape culture, and raised

wine into a religious symbol.

This millenary inheritance

we are so proud of although

struggling is still alive and

uninjured in some grape-

growing regions, due in part

to the slow rhythm of both

viticulture and oenology.

It is important to maintain

this patrimony, even when

forces finance its destruction

without even perceiving it. It

is the duty of people devoted

to wine and culture, to join

efforts to defend this heritage.

HISTORICAL WINES

There is no unanimously

accepted definition for

“historical wine” but in the

present context, a definition will

be used that has been adopted

by the Association of Historical

VINHOS HISTÓRICOSPORTUGUESES,UM SÍMBOLO DANOSSA CULTURA

Wines of Portugal, created

in 2008 to protect a cultural

heritage in risk of extinction

Thus, “historical wine” is

the wine produced using

ancestral grapes and ancient

wine-growing techniques and

knowledge, presenting its own

peculiarities, which consumers

in our century should not ignore

if they want to understand

these wines. The most relevant

Portuguese historical wines

are Green wine (vinho verde)

produced with grapes from

vines cultivated in tall forms

such as the ‘Enforcado’,

‘Arjões’ or ‘Ramadas’, sandy

soil Colares, Medieval Palhete

from Ourém, and Pot wine

from Alentejo and Azores wine.

Green Wines (Vinho Verde)

Produced in the Northwest of

Portugal, cultivars producing

green wines are very popular

in the Minho region, and are

cultivated by many small grape

growers. Their distinctive

characteristics result from

being produced in elevated

trellises (Fig. 1) and by being

sparkling (gaseous peak), as a

result of the activity of lactic acid

bacteria. The ‘Enforcado’and

‘Ramadas’grapevines may be

of Etruscan origin, and are freely

found in the Minho landscape.

The ‘Arjões,’ developed from

the ‘Enforcado‘vine, is more

recent and became common

from the end of the 19th century.

Sandy soil Colares

Both white and red wines from

Colares, 30 km from Lisbon and

next to the Atlantic coast, are

jewels of Portuguese oenology.

Although of remote antiquity,

they reached a peak during

the 19th century, phyloxera

epidemic, which devastated

the vinifera industry in Europe,

since the vines, planted in sands

with great depth, resisted the

plague. Culture is unusual with

the untrellised vines crawling

on the sand, resembling a giant

octopus with thick tentacles

(Fig.2). The heat radiating from

There are five massive sulphide

Zambujal and Lombador. The

expectations of growing were

developed, such as:

• To maximize and to make a good use of natural and materials resources;

• A great effort on invest-ments;

• A focus in new explora-tion areas (currently controls more than 1.357 square kilo-meters);

• Selective employee hire to strengthen technical and growth capability;

• Feasibility Studies of

• Project of Copper and Zinc Recovery from Tailings.
