Clos Pegase Mitsuko's Vineyard Chardonnay is an estate-grown white wine from the Los Carneros appellation within Napa Valley, California. The wine is named for Mitsuko Shrem, the late wife of winery founder Jan Shrem, who introduced him to the world of wine and inspired him to establish Clos Pegase as an iconic Napa Valley destination.

Mitsuko's Vineyard spans 365 acres of rolling terrain in Carneros, featuring diverse soil types, elevations, slopes, and aspects that create countless distinct microclimates ideal for cool-climate viticulture. The region's proximity to San Pablo Bay provides moderate temperatures and marine influence that allow for slow, even ripening, preserving natural acidity in the fruit.

This Chardonnay displays aromas of fresh cantaloupe, jasmine blossom, and pear with subtle oak tones, along with notes of brioche, crème brûlée, and peach. On the palate, the wine shows cut melon, a touch of pineapple, Asian pear, and fresh-cut hay, all framed by balanced, structured acidity and judicious French oak that adds complexity without overwhelming the fruit. The wine has earned 92-point ratings from prominent critics including James Suckling and praise from Wine Enthusiast for its elegance and precise fruit character.
