The 2021 Radio Coteau Heitz Chardonnay is a white wine from the Sonoma Coast, California. Produced by Radio-Coteau, this wine is crafted from Chardonnay grapes and is known for its balanced and nuanced profile.

According to Jeb Dunnuck, who awarded it a score of 94, this Chardonnay was fermented in barrels with about 20% new oak. It exhibits a "golden youthful hue" and is characterized by ripe notes of pineapple, lemon curd, and delicate baking spices. Dunnuck describes it as full-bodied, with a nutty palate complemented by yellow flowers, yellow apple, and ripe citrus. He suggests that it will reach its peak between 2024 and 2034, emphasizing its potential for aging.

Vinous offers an even more enthusiastic review, scoring the wine at 95. Describing it as a "super-classic Radio-Coteau wine," the review highlights its floral and understated qualities. The wine showcases a complex array of flavors, including dried pear, white flowers, graphite, spice, mint, and a hint of passionfruit. The review notes the significance of the Heintz vineyard site in Sonoma, stating that its pedigree is evident in this bottling.

Both reviews praise the wine's complexity and finesse, with Vinous citing the Heintz vineyard's reputation as a key factor in the wine's excellence. The 2021 Radio Coteau Heitz Chardonnay is noted for its subtlety and elegance, making it a standout choice for those who appreciate a well-crafted Chardonnay. While the wine is approachable now, it also promises to develop further with age, offering a rewarding experience for those who choose to cellar it.
