Indian Wine Producers Face Earlier Harvests and Greater Climate Variability

In a Sommelier India opinion article, Manuela Lo Conte argues that climate change is putting pressure on the systems Indian growers use to manage vines in a tropical climate. Indian vineyards rely on double pruning to create a resting period and produce one commercial harvest, rather than depending on the long, cold winter that brings natural dormancy in many European regions. Lo Conte says warmer winters and less predictable weather are testing that approach.

The article cites reports from Indian producers that harvest dates moved forward by about five days over the past two vintages, while noting that seasonal variation remains considerable. Lo Conte says compressed picking periods can bring more fruit into wineries at once and make labour and harvest logistics harder to manage. She also describes a ripening challenge: sugars may rise faster than tannins, colour compounds and flavour precursors develop, leaving growers to balance freshness and alcohol against flavour and structure.

The piece points to rainfall arriving at unexpected times, hail risk and warmer nights as additional management concerns. It also highlights soil practices—including cover crops, compost, reduced tillage and greater biodiversity—as ways growers can support water retention and soil resilience. In the cellar, Lo Conte says warmer fruit can increase microbiological pressure and that temperature control and hygiene require closer attention.

Lo Conte also raises the question of whether familiar international varieties will remain consistent choices as conditions change. Indian consumers, she writes, commonly recognize varieties such as Cabernet Sauvignon, Merlot, Shiraz, Chardonnay and Sauvignon Blanc, creating a commercial reason to maintain them. The article identifies PIWI vines, developed through conventional cross-breeding for fungal-disease resistance, as a potential addition to growers’ options, rather than a wholesale replacement for established varieties. It notes that higher-elevation vineyards can moderate temperatures and frames adaptation as a combination of site, vineyard management, soil care and variety selection.
