Substance wines are crafted with an unapologetic commitment to quality and sourced from Washington’s premier vineyards. Every bottle delivers intensity and authenticity — a pure expression of Washington wines.

Using low-intervention, small batch winemaking techniques, we work strictly with what nature hands us—sustainably grown grapes, wild yeasts, lees, a whisper of SO₂, and time. Precision at every stage leads to uncompromising quality—regardless of price. The critics notice, and they’re not wrong.

Our wines are free from the 72 additives allowed in American wine; we keep it pure, no exceptions.

His hands-on, low-intervention approach embodies his dedication to crafting wines that reveal the authentic character of Washington’s terroir.

Originally created with a mission to produce exceptional wines, Substance focuses on ultra-premium quality that’s accessible to all. Brennon meticulously sources sustainably grown grapes from premier Washington vineyards, using native yeast fermentation, lees aging, and minimal SO2 to allow for a true expression of the vineyard and to capture the unique qualities of each season. Every bottle in the Substance portfolio—from the Cabernet Sauvignon and Chardonnay to the recently released Red Blend—reflects Brennon’s commitment to purity and quality, embodying real wine for real people, crafted to be enjoyed every day.
