Costa di Giulia is an estate-cru white wine produced by the winery Michele Satta in the coastal Bolgheri appellation of Tuscany, Italy (often referenced with Tuscan coastal origins, though technically carrying a Bolgheri Bianco DOC designation rather than a broad Toscana IGT).

Typically 60% Vermentino and 40% Sauvignon Blanc (produced since 1997). Grapes are hand-picked and whole-cluster pressed. Fermented separately (Vermentino usually in concrete or steel, Sauvignon Blanc in stainless steel or concrete depending on the vintage). Matured on fine lees for roughly six months.

Crisp, medium-bodied, and layered with notes of white pineapple, citrus, stone fruit, white flowers, tarragon, lime blossom, and a distinct sea-breeze saline/mineral lift.

James Suckling – 94 Points: Describes it as a "polished and complex wine" featuring aromas of candied citrus, wild herbs, and angelica. The review praises its medium body, silky texture, refreshingly integrated acidity, and a distinctive savory finish with "iodine depth".

Wine Enthusiast – 93 Points: Notes that the nose swirls with "cool, delicate, saline aromas of crushed rocks, white flowers, white peach, and lemon." The palate is dominated by lemons, limes, and just-ripe peach, leading into a nuanced finish of tree fruits, nuts, and a salty, bitter almond skin complexity.
