Drop dead gorgeous chardonnays

TOP PICK

Three Sticks

Three Sticks, 2015 Durell Vineyard, Sonoma Coast Chardonnay, 14.5% alcohol, $55. ★★★★1/2

A chardonnay with great complexity — bright stone fruit, hazelnut and creme brulee. Lush, but manages to be balanced. Great minerality. Supple texture, with a lingering finish. Absolutely knockout.

Tasty ALTERNATIVES

Merry Edwards, 2014 Olivet Lane, Russian River Valley, Sonoma County Chardonnay, 14%, $60. ★★★★1/2: This is a striking chardonnay with great depth. Notes of melon, fig and spice. Supple texture. Rich, yet balanced. Nice length. Extremely well crafted. Impressive.

Cuvaison, 2015 Adda Carneros, Napa Valley Chardonnay, 14.2%, $26. ★★★1/2: This is a pretty chardonnay weighted to stone fruit — peach and apricot. A hint of honeysuckle and a splash of lime in the mix. A steal for the price.

Dierberg, 2014 Dierberg Vineyard, Santa Maria Valley Chardonnay, 13.8%, $32. ★★★★: A blousy chardonnay with rich flavors, but it has a nice underpinning of bright acidity. Notes of ripe apple, melon and toasty oak. Lovely.

Bravium, 2015 Russian River Valley Chardonnay, 14.1%, $25. ★★★★: A chardonnay that over delivers for the price. Layered with notes of pineapple, toast, honey and honeydew. Bright acidity, coupled with good minerality. The pineapple gives this chardonnay a refreshing twist. Delightful.
