The 2018 Morlet Family Vineyards Les Petits Morlet Sauvignon Blanc offers a noteworthy expression of California's North Coast. This vintage, composed of 85% Sauvignon Blanc and 15% Semillon, originates from barrels that did not make it into the producer's premier blend, La Proportion Doree. Despite being a "second" label, this wine has garnered impressive reviews.

Robert Parker's Wine Advocate awarded this wine a score of 92, noting its vibrant aromas of lemon curd, key lime pie, and apple blossoms, complemented by hints of oyster shells and elderflower. The palate is described as medium to full-bodied, bursting with citrus and apple flavors, and finishing on a chalky note. Only 240 cases were produced, highlighting its limited availability.

Vinous, also rating it 92, praised the 2018 vintage as an "absolutely gorgeous second wine," emphasizing the clear expression of Sauvignon Blanc character. Antonio Galloni of Vinous remarked on the wine's lemon oil, mint, white flowers, and chalky notes, which contribute to its brilliant upper register while maintaining the textural depth characteristic of Morlet's wines.

Jeb Dunnuck, with an even higher score of 94, highlighted its beautiful and complex nose of crushed lime, orange liqueur, and earthy minerality. Dunnuck described the wine as rich and medium to full-bodied, with great acidity and a salty, mineral-like quality. He praised its "blockbuster of a finish," noting the presence of toasty oak and referring to it as "one hell of a second wine."

Overall, the 2018 Morlet Family Vineyards Les Petits Morlet Sauvignon Blanc is a testament to the winery's ability to produce exceptional wines, even from declassified lots. It offers a complex and rich drinking experience, backed by strong reviews from respected critics.
