Navarra (DO)
From Wikipedia, the free encyclopedia
Navarra Denominación de Origen (DO) extends over practically the entire southern half of the autonomous community of Navarre (Spanish Navarra, Basque Nafarroa). The vineyards are on the lower slopes of the Pyrenees as they descend towards the basin of the river Ebro.
The region used to be renowned only for its rosé wines but in recent years has been producing quality reds and whites as well.

[edit] History
The earliest historical data on grape growing and wine production in Navarra dates from the 2nd century BC, when the ancient Romans built wineries (bodegas). Remains of winery equipment and installations have been found at the archaeological excavations in Arellano (Villa de la Musas), Falces, Lumbier and Muruzábal de Andion (Villa de Andelos).
In the Middle Ages, when Navarre was a powerful independent kingdom with close ties to France, viticulture prospered, partly due to the demand from the pilgrims on the Camino de Santiago (Way of St. James). In the 12th century, the wine from Navarre was recommended to pilgrims in guidebooks, and was also exported abroad.
Towards the end of the 18th viticulture was the main agricultural activity of the region. In 1855 there was an outbreak of oidium which affected wine production, three years after a similar outbreak in the Bordeaux (France) region. However, in 1892, the phylloxera plague devastated the vineyards, destroying an estimated 98% of the 50,000 ha of vines planted at that time.
At the beginning of the 20th century, the vineyards were replanted by grafting onto New World rootstock. Wine cooperatives were formed and successfully increased production by exporting large quantities of wine in bulk.
During the 1980s private wineries and cooperatives began bottling and labelling quality wine. The statutes of the Denominación de Origen, which were originally approved in 1933, have been updated to reflect the shift of emphasis from bulk production to quality production.
[edit] Geography
The DO is divided into 5 sub-zones, each one of which has a distinct identity and produces characteristic wines.
[edit] Valdizarbe
Valdizarbe, the northernmost sub-zone on the upper reaches of the river Arga is a strategic location on the Way of St. James as several paths crossing Navarre converge there. The vineyards cover 25 different municipalities.
[edit] Tierra Estella
To the west of Valdizarbe, Tierra Estella covers 38 different municipalities and extends along the Way of St. James in Western Navarre, on the middle reaches of the river Ega.
[edit] Ribera Alta
The Ribera Alta sub-zone is centred around the town of Olite on the left bank of the river Ebro, above the lower reaches of the rivers Arga, Ega and Aragón, and covers 26 municipalities.
[edit] Baja Montaña
This sub-zone covers 22 municipalities and is located in the northeast of the DO, on the middle reaches of the river Aragón.
[edit] Ribera Baja
The Ribera Baja sub-zone is in the south of Navarre and is the most important of the five in terms of area and number of wineries. It covers 14 different municipalities, all on a dry, sandy plain on the right bank of the river Ebro.
[edit] Climate
The climate in Navarra is continental (long, hot , dry summers and cold winters). The northern sub-zones have a dry continental climate with Atlantic influences and with only moderate heat during the period when the grapes are ripening, as the nights start to get cooler during the month of August.
Average rainfall in the DO is 625 mm per year. In the areas at higher altitudes, there is the occasional risk of frost and of violent storms.
[edit] Grapes
Red variety vines, for production of reds and rosés, represent 95% of the all vines planted in the DO, though this percentage is decreasing as more white varieties are planted. The traditional Garnacha represents 32%, Tempranillo 36%, Cabernet Sauvignon 13%, Merlot 11% with Graciano and Mazuelo making up the remaining percentage. The main white varieties are Viura, Chardonnay and Garnacha Blanca.
Most vines are trained along trellises (en espaldera) to maximise exposure to the sunlight and to facilitate mechanisation, as opposed to being planted as low bushes (en vaso). Planting density is over 2,400 vines/ha. Yield in all five sub-zones is below the authorised maximum of 8,000 kh/ha, and vary between 6,200 kg/ha in Valdizarbe and 7,800 kg/ha in the south.
The only authorised white variety is Viura, but Chardonnay, Garnacha Blanca, Malvasia and Moscatel de Gano Menudo are also permitted.
The authorised red varieties are Graciano, Tempranillo and Cabernet Sauvignon but Garnacha, Merlot and Mazuelo are also permitted.
