Gusbourne releases rare cellar wines to mark 20th vintage

English sparkling wine producer Gusbourne is celebrating 20 years of winemaking by releasing rare bottles from its cellar, including just four bottles from its very first vintage in 2006. The limited Cellar Release collection comprises around 250 bottles drawn from parcels held back over two decades, with prices ranging from £45 to £105, and it's available exclusively to members from mid-July through early August 2026.
