Kelleher produces Cabernet Sauvignon and Chardonnay from Oakville, the Napa Valley appellation renowned for structured, age-worthy reds. The winery's portfolio centers on vineyard-designated bottlings: Bari's Vineyard Cabernet Sauvignon and Brix Vineyard Cabernet Sauvignon showcase the region's ability to balance power with refinement, while Three Sisters Unfiltered Chardonnay reflects the white wine potential of the area. Both Wine Enthusiast and Wine Advocate have rated these wines, affirming their quality across the range. Oakville's gravelly soils and moderate climate create conditions for Cabernet that develops deep color and tannin structure, characteristics evident in Kelleher's vineyard-focused approach.
