Kalleske Clarry's GSM 2025 is a vibrant, plush and generously flavoured blend of Grenache (48%), Shiraz (36%) and Mataro (16%) from the Kalleske family's certified organic and biodynamic estate in the Barossa Valley. Named in honour of Clarence “Clarry” Kalleske — the fourth generation of the family to tend these vines, farming from the late 1920s until his retirement in the 1990s — Clarry's draws from over a dozen blocks, with the oldest Grenache vines dating to 1940. Deep, dark crimson in colour, revealing aromas of red berries, blueberry pie, fresh cherries, potpourri, spice and musk. The palate is medium-bodied, juicy and immensely flavoursome, with gentle chalky tannins and a long, stylish finish. Vegan, organic and biodynamic certified.

Wine Sellers Direct Verdict
Clarry's GSM is one of the Barossa Valley’s most consistent and rewarding mid-range reds — a wine that delivers genuine old-vine complexity and biodynamic integrity at an accessible price point. The 2025 vintage is a standout release, shaped by warm, dry conditions and lower yields that concentrated flavour without sacrificing the freshness and vibrancy that define the Clarry’s style. At its core, this is a Barossa GSM for buyers who value producer story, sustainable farming and drinking pleasure in equal measure. Exceptionally approachable now, it will also reward cellaring over the next five years.
Who Should Drink This?
Choose Clarry’s GSM 2025 if you: enjoy vibrant, fruit-forward Barossa reds with genuine old-vine character; value certified organic and biodynamic production; are looking for a versatile food wine; or want a reliable, crowd-pleasing red for immediate enjoyment or short-term cellaring.
This wine may not suit you if you prefer: a more structured, oak-driven Barossa Shiraz style — in which case a single-variety Kalleske Shiraz or a Barossa Cabernet may be a stronger choice.

Another classic Barossa GSM offering richer fruit and broader texture. A useful comparison for those exploring the style across producers.
