BAROSSA VINTAGE 2026 COMMENTARY – the Sons of Eden perspective
Vintage 2026 had many twists and turns that took us on a 74 day journey. Starting off on the 26th February, on the tail end of an extended warm dry period, through to a wet mid-point and ending with a classic Indian Summer.
Experience and expertise, combined with a cool head, helped us navigate our harvest from the warm Western Ridge of the Barossa Valley and conclude in the high-altitude cool sites of central Eden Valley.
The reds across both Barossa Valley and Eden Valley look outstanding with small berries, and generally lower yields, contributing to concentrated vibrant flavours and ripe velvety tannins. Shiraz from Eden Valley particularly benefited both from the March rainfall and mid-April Indian Summer that will potentially become iconic examples of this variety.
Ample winter rains with useful top-ups through Spring enabled the slow development of full vine canopies with balanced crop potential. A cool November slowed development and put us on a course for a later harvest. On the 12th November a frost affected a small number of lower lying vineyard sites significantly curtailing their yield.
One of the key climatic influencers of vintage 2026 was the significantly dry and warm conditions from December to the end of February. This ensured small berries and low yields, a significant factor in achieving highly coloured, concentrated red wines.
Overall the growing season was slightly warmer than average, however, most of the heat was in late Janurary, prior to veraison, and didn’t affect the berry composition.
Rain at the beginning of March of 30mm to 60mm delayed harvest and in some cases caused varying degrees of berry split in the more stressed vineyards.
Riesling harvest from Eden Valley was in full swing prior to the rain and in many instances recommenced after the canopies dried out. We saw some isolated examples of berry split on the wetter sites.
The Rieslings are pristine and intense with an enduring minerality courtesy of the balanced natural acidity retained at harvest.
In summary we believe this will be a memorable Barossa vintage.
