Sterling's barrel-fermented 2020 Chardonnay Reserve comes from the Gamble Ranch and Star Vineyard (in Rutherford) and spent 18 months in 75% new French oak. Aromas of buttered cashew, ripe tangerine and grilled pineapple are joined by a slightly custardy note. Medium to full-bodied, this is round and generous on the mid-palate, then finishes a bit tart and edgy.
