Grenache in the Vineyard • Dr Linda Bisson, UC Davis: “Grenache is not difficult to ripen … it may be one oF the most difficult grapes to work with, perhaps more difficult than Pinot Noir”. • Grenache shows its terroir in the glass • Sensi?ve to vineyard locaon, soil and vintage variaons, thus site selec?on is Fundamental • Top internaonal sites – deep, well drained soils, inducing moderate vigour with moderate to low water availability • Dry-Farming or minimal irrigaon is advised. • Does well in windy areas due to strong upright growth oF canes. • Controlling the vine’s vigour is essen?al. • Suffers From “dead arm” or Eutypa dieback • Moderate suscep?bility to Phomopsis • Sensi?ve to downy mildew, especially in cool, wet growing condi?ons • Finding suitable excellent clones is a challenge • French clone GN 70 is very produc?ve, most widely planted in France and SA. • 1064, 513 and 516 From Vi?tec is beDer • Internaonal clones with poten?al: US (Clone 2D), France (ENTAV-INRA 136 and 435), Spain (clones From Navarra – EVENA 11, EVENA 13, EVENA 14 and EVENA 15, VN- QUALITAS, clones From Cas?lla y Leon – CL 55, clones From Aragon – ARA 2 and ARA 24, clones From Rioja – RJ 21). • Select a drought resistant rootstock that induce moderate vigour – R110 • Plant Grenache as bush vines head pruned • Buds Fairly early • Requires plenty oF sunshine and can tolerate sustained summer temperatures oF 40 °C • Need a long growing cycles to achieve phenolic ripeness • Nitrogen Fer?lisaon should be limited – shows its best at low yields • Indicator cul?var For magnesium deficiency • Pruning should be severe to control the number oF buds and spurs • Trimming the ?ps oF developing shoots near the end oF the flowering period to lessen incidence oF couloure (afspeen) • Suckering/shoot thinning in spring and early summer to control the number oF shoots per vine • Green harvest/bunch removal aer veraison is essen?al – big bunches, with big shoulders. • Grenache clusters are compact and can be subject to bunch rot at harvest, thus basal leaves may be removed Following Fruit set • Use oF permanent cover crops to devigorate the vines can be considered. • To produce premium wines, yields oF 35 hl/ha or less are recommended, colour and extrac?on suffers with high yields Clones • Charles Visser – three clones oF Grenache Noir available – French clones ENTAV-INRA 70, 513, 516 and 1064. • Vi?tec imported From Australia in 2005 – GN – 179, 33, SAVI6 • Clone 70 most planted – average to high produc?on clone, berry/ spicy aromas, can some?mes lack structure and colour • Clone 513 – average to lower Fer?lity, average to lower vigour clone, good quality, higher polyphenols and medium compact bunches • Clone 516 – average produc?on, wine typical oF cul?var • Clone 1064 – lower produc?on, small to medium bunches, high wine quality, wine with good tannin structure. • We have limited clones capable oF producing high quality wines available. When to harvest? Figure 7 – Evolu;on of Grenache during ripening (year 1999, Rhône) • Compared with other grape varie?es, Grenache contains a low amount oF anthocyanins, composed mostly oF 3-glucoside malvidine (75% oF all anthocyanins), a component that oxidises easily under the influence oF temperature and light. • Grenache berries are characterised by a hard, tannic and herbaceous skin that aains its colour late during ripening, taking some ?me un?l berry colouraon is complete. • Throughout maturity Grenache develops intense Fruity aromas with an evolu?on towards the jammy/confiture flavour spectrum iF leB too late. • Seeds retain green characters throughout ripening and only reach maturity late. • When Grenache is harvested too early, the poten?al alcohol deficit is normally Followed by colour deficit and green tannins. • Sugar ripeness and phenolic ripeness are normally not aligned. • Grapes are normally harvested riper For longer ageing wines where colour and structure are important; wines develop spicy aromas, along with ripe Fruit and poten?ally cooked and jammy Fruit notes when pushing ripeness limits. • Wines des?ned For early consump?on, tannin and colour extrac?on are less important and the goal normally is to harvest to Favour red Fruit and berry character. • Different schools oF thought: Montse Nadal, proFessor oF Oenology at Tarragona University, comments that achieving phenolic ripeness is less cri?cal compared to other grape varie?es because oF Grenache’s lower phenolic content – thus aim For lower alcohol, higher acids and less overripe flavours. Zelma Long is oF the opinion that in Grenache the silkiness oF texture and the soBness oF the wine comes in part From ripe tannins. • Regarding the alcohol debate, one should keep in mind the opinion oF the market, sommeliers and other opinion Formers.
