The life-force of the vine vs climate changes
High quality anticipated in the wine-cellar
Harvest is literally upon us with some white grapes already safely in the cellar and several red grape varieties being picked at this very moment. But it’s still too early to draw any definitive conclusions about the 2021 harvest, since producers up and down the peninsula are still relying on predictions. Which, however, are encouragingly positive.
Let’s give a brief overview of the growing season. The weather brought three distinctive phenomena that had critical impacts. A spring freeze plunged temperatures that delayed bud-break and shoot growth by some 10 days, whose effects are still being felt in the current ripening stage, while the south suffered under water deprivation and the north was hit by torrential rains. The common thread that emerged from these challenges, though, was the current outstanding health status and overall quality of the fruit, a situation that augurs well for fine wines from 2021. Delivering the best results seem to have been the most ecologically-sensitive vineyard operations and precision agricultural practices, approaches that protect and express terroir in the face of increasingly threatening climate changes.
We asked producers from north to south what they thought and how they were managing to transform climate threats into quality outcomes.
In Trentino, at the historic San Leonardo wine estate, owner Anselmo Guerrieri Gonzaga reports that “the year opened cold and very rainy, which tried us no end. Then, in early August, the weather really began to smile on us, and we are continuing even now to enjoy fabulous, sunny days, with significant day-night temperature differentials as wide as 18oC. If September follows the same pattern, we have a realistic hope of bringing in a truly superb harvest.”
Over in Lombardy, in the Oltrepò Pavese hills, the 200 hectares of Conte Vistarino allow a clear picture of overall prospects for the general area. Ottavia Giorgi enthuses: “We have extreme expectations for this harvest, which promises to be even better than we could imagine.” Brimming groundwater reserves, crisp spring weather, painstaking attention to vine-row vegetation, and a healthy status of the clusters harken back to the 2018 season, while the tannins look to be finer-grained than in preceding years. The white grapes are currently exhibiting outstanding pH and acidities, which bodes well for the sparkling base wines as well. “We are expecting very heightened aromatics and crisp acidities in our Pinot Noir, a gift of those quite wide temperature differentials in the hot summer months.”
In the Colli Fiorentini, just outside Florence, at Torre a Cona, Niccolò Rossi di Montelera has expectations for “a good quality vintage but for a crop smaller than in 2019 and 2020. Reflecting this growing season’s characteristics, the harvest will kick off slightly later than in previous vintages, beginning with Merlot in the latter half of September, while Sangiovese and Colorino will wait until the end of the month.”
At Castello di Brolio, one of Chianti Classico’s iconic estates, Francesco Ricasoli explains that the year has brought a one-two punch of freezes and hot spells. “Still, our white grapes, which were picked already in late August, are superb, in both quality and quantity. We expect to bring in our Sangiovese around mid-September; the crop will be down a bit, but quality definitely up. Cluster size is somewhat small, as in 2017, but they show deeper colour, aromatic intensity, and better concentration.”
Just a few kilometres away, Giovanni Mazzei underscores that the current season “is yet more proof of our vines’ ability to withstand challenging weather conditions thrown at them.” In particular, in the Siepi zone, “where deep soils and a high percentage of clay help retain much more moisture than other areas, a generous water supply for the roots and wide day-night temperature ranges are ensuring excellent ripeness levels.”
At Castello di Querceto in Greve in Chianti, the unfavourable weather phenomena reduced the crop load by about 10%. Alessandro François is cautious about making any definitive judgments. While waiting to see what the next few weeks will bring, he says that “quality looks very good, but our Sangiovese growing at 400-520 metres still needs more time.”
The heat spells impacted Gaiole in Chianti, too, but director Luca Vitiello of Bertinga explains that “good canopy management protected the clusters and careful ground-working allowed the vines to recently complete veraison, a bit late perhaps, but with no excessive stress. These are the foundations for an excellent harvest, which we are looking for in the next days of September for the Merlot vineyards and the first half of October for Sangiovese.”
Moving into Montalcino, Emilia Nardi, owner of Tenute Silvio Nardi, tells us that “thanks to our 2020 post-harvest operations, the vines enjoyed a plentiful supply of water, which allowed them to handle this season’s lack of it. Right now, the fruit shows surprisingly good balance and the vines good canopy development.”
Heading towards the Tuscan coast, where the vineyards of the Tenuta di Ghizzano lie in the Pisan hills, Ginevra Venerosi Pesciolini declares herself satisfied, since “the white grape varieties are in very good shape indeed. For some of the reds, however, the situation is somewhat more complicated. The Merlot is already in the cellar, and the quality seems quite high, but we’re hoping for a bit more rain, which would give our Sangiovese perfect phenolic ripeness.” Rains have already been of providential help this year, and “our clay-rich soils were able to absorb the rains we saw in May, which helped the vines cope with the summer drought.”
In Riparbella, the just-emerging Colline Albelle operation uses one of its tools, dry-farming, to prevent heat stress. Winery director and winemaker Julian Renaud explains that “we also mow the cover-crop in mid-May, leaving everything on the ground, we keep canes short to prevent evapo-transpiration, do no leaf-pulling, and we utilise biodynamic preparations. All that helps us maintain optimal balance in the vineyards and a very gradual ripening process. This year, we expect about a 15-day delay in starting our harvest.”
Along the same coast, in Bolgheri, Ornellaia director Axel Heinz, notes that its unique configuration of quite deep soils with high percentages of clay and limestone encourages the vine roots to go deep in search of water, which helps them resist the long stretches of dryness here. In addition, “Our sunny, dry conditions help the early-developing white varieties to fully ripen.” And finally, a drop in temperatures created “ideal conditions for the final stage of ripening, thus giving the red varieties all the time they needed to reach perfect ripeness.”
In the Maremma, the Fattoria Le Pupille team can draw a sigh of relief at what promises at this moment to be a great vintage. “The rains in mid-July gave us a welcome boost, relieving the heat stress and bringing the growing year to a blessed close.” A stance of hope, therefore, from Ettore Rizzi, estate agronomist and oenologist of the estate founded by Elisabetta Geppetti.
Also in the Maremma is Castello di Vicarello, where the hillslope position of the vineyards was proof against the spring freezes, and in the summer ensured them cool night-time temperatures that warded off heat stress. Brando Baccheschi Berti evinces pronounced satisfaction over fruit quality: “Wonderful acidities and full berries, proof that our old, deep-rooted vines are holding up well. My impression is that it’s going to be a beautiful vintage.”
In the Val d’Orcia, finally, with benchmark operation Tenuta di Trinoro, a textbook-perfect vintage is expected. Here, too, the difficult weather brought challenges, but director Calogero Portannese expresses strong confidence in those “significant day-night temperature variations, which encouraged impressively-high quality in the fruit. Still, the harvest is a ways off yet, and we have to wait to see what autumn will finally bring us.”
SICILY and SARDINIA
Over the sea in Sardinia’s Gallura district, Massimo Ruggero, managing director of Siddùra, explains that the area did experience the spring freezes, but the impact was not severe, “thanks to our particular climate here in this valley, our crop was down just slightly compared to the previous year. Overall grape health is good, and the final crop should almost equal that of 2020.”
Let’s conclude our journey in Sicily. Mount Etna suffered a torrid, dry summer, and Vincenzo Lo Mauro, director of Passopisciaro, helped the vines by supplying night-time emergency irrigation. “The Chardonnay harvest started early, right after mid-August. The grapes were in wonderful condition, heathy and aromatic, and they’ll give us a very intense, firm-structured wine. Regarding the reds, we’re hoping the heat will drop and that we’ll receive some rainfall, which will help them get to that perfect point of ripeness.”
And now, there’s nothing we can do but wait.
