In the Gorizia Mountains due to high temperatures, a third less grapes

In the Goriških Brdih region of Slovenia, wine producers anticipate harvesting 4800 tons of grapes this year, which represents two-thirds of the usual annual yield. The significant reduction is primarily attributed to high temperatures during the summer, which caused premature ripening and reduced overall production compared to other agricultural products. However, the quality of the harvest is expected to be good, with high sugar content and balanced acidity. Director Silvan Peršolja of Kleti Brda emphasized the need for adaptive measures such as shading nets and improved irrigation techniques to mitigate future losses. He also noted that those who implemented expert recommendations saw smaller yield reductions. While the current harvest is of good quality, final assessments will be made after the Martin harvest. Despite lower quantities, prices per kilogram remain stable at around 0.9 euros for standard programs and up to 1.2 euros for premium programs.

In Goriških Brdih will see a third less grape harvest this year due to high temperatures, according to reports from local cooperatives. Kleti Brda expects to purchase 4,800 tons of grapes, which represents two-thirds of the usual annual yield. The primary cause for the reduction is attributed to prolonged periods of high temperatures, although drought conditions affected vineyards less severely compared to other agricultural sectors. The early harvest began as early as August 8th, concluding in recent days. This early start has been noted even among the oldest local viticulturists, who have not observed such a season pattern before. Grapes ripened faster due to sustained heat and dryness, which was beneficial as there were no signs of vine disease. Director of Kleti Brda, Silvan Peršolja, emphasized the need for future considerations regarding shading vineyards with special nets, which could also serve as protection against birds. He stressed the importance of proper irrigation management. Peršolja also highlighted the positive effects of winter professional training for viticulturists. Those who adjusted their vineyard practices based on expert advice saw a smaller yield loss, though the extent varied depending on location, variety, and seasonal work methods. Peršolja stated that preparing vineyards for such extreme conditions is currently the only response to the new reality. In these conditions, both Rebula and green Chardonnay performed well, surprising some. Main enologist Darinko Ribolica confirmed that the current grape quality is good, with high sugar content and good acidity. However, he noted that the final assessment of the vintage should wait until after the Martin harvest. There are approximately 2,000 hectares of vineyards in Goriških Brdih, half of which are managed by 200 viticultural families working under the cooperative of Kleti Brda. Peršolja expressed concern that the reduced yields might lead to further abandonment of viticulture. Despite the lower quantities, the price per kilogram of grapes is expected to remain at last year’s level. The average purchase price for the standard program is set at 0.9 euros per kilogram, while the premium and selection programs range up to 1.2 euros per kilogram.
