Gran Moraine Chardonnay is an elegant white wine from the Yamhill-Carlton District within Oregon's celebrated Willamette Valley appellation. Produced by Gran Moraine, a winery under the Jackson Family Wines portfolio, this Chardonnay is crafted at their estate vineyard located at 17090 NE Woodland Loop Road in Yamhill, Oregon, a Certified Sustainable Winery.

The Yamhill-Carlton AVA is renowned for its ancient marine sedimentary soils and a cooler, drier microclimate that produces wines of exceptional balance and complexity. Gran Moraine's Chardonnay from this region consistently earns critical acclaim, with recent vintages scoring 94–97 points from publications including Jeb Dunnuck, Vinous, and Decanter. The wine reflects the winery's philosophy of disciplined viticulture paired with freedom of expression in the cellar, resulting in a Chardonnay of notable depth and finesse.

This Costco offering is sold in a case pack of 12 bottles, each 750ML. The wine is well-regarded for its ability to age gracefully, though it also drinks beautifully on release.
