Sourced exclusively from the Beckstoffer To Kalon Vineyard in Oakville, Old Sparky showcases the finest barrels from Schrader’s multiple To Kalon lots, blended into a wine of monumental depth and balance.
Tasting Notes
The 2021 Old Sparky opens with a commanding bouquet of blackcurrant, graphite, and warm spice layered over cedar and violets. The palate is dense yet refined, offering tremendous energy and concentration. Powerful tannins frame a core of ripe blackberry and cassis, leading to a remarkably persistent finish marked by freshness and minerality.

The 2021 vintage—defined by low yields and a long, even growing season—produced fruit of exceptional purity and tannin polish. Schrader’s micro-lot vinification preserves each vineyard block’s distinct character before the final selection for Old Sparky.
