🍇 VitiForce Weekly Update | 04/08/2026
Hello vinegrowers,
We can't believe it's already August! It feels like only yesterday we were on frost watch, and now we're in full veraison. It's an exciting stage of the season, especially for vineyards that escaped the spring frosts and have established, mature vines.
Unfortunately, the same can't be said for young vineyards. With the fourth heatwave in a row, many newly planted vines are under significant stress.
🍇 Veraison
Veraison is one of the most exciting stages of the growing season. It marks the beginning of grape ripening and is most noticeable on red varieties as the berries begin changing colour.
Across many mature, non-frosted vineyards, veraison is now well underway. The earliest varieties continue to be Pinot Noir Précoce, Rondo, Regent, and Ortega, with Pinot Noir and Pinot Meunier now progressing well into this important stage.
🌱 Vineyard Floor Management
Last week we continued several vineyard floor management trials to evaluate different methods of improving soil moisture retention.
Rather than simply mowing, we're assessing how maintaining additional ground cover can provide shade to the soil surface, helping reduce moisture loss and minimise soil cracking during prolonged hot weather.
Every vineyard is different, and the most effective approach depends on soil type, site conditions, and available equipment.
☀️ Drought Stress in Young Vines
While mature vines are generally coping well with temperatures reaching 38°C on some sites, young vines are showing clear signs of drought stress, with wilting becoming increasingly common.
Their developing root systems cannot yet access deeper soil moisture, making them much more vulnerable during extended dry periods.
Management options may include green harvesting to reduce crop demand and, where possible, targeted irrigation to help vines establish successfully.
📉 Yields and Vintage Outlook
Current observations suggest many vineyards are carrying smaller bunches with smaller berries, which is likely to reduce yields. However, these conditions can also produce excellent fruit concentration and outstanding wine quality.
