The Nose

Arinto wines typically present a vibrant aromatic profile dominated by bright citrus notes—think lemon zest, lime, and sometimes grapefruit—along with delicate floral hints of orange blossom. As the wine ages, subtle secondary aromas of green apple and hints of dry hay can emerge, leading to tertiary notes of stony minerality and a restrained, toasty character in more complex examples. Overall, the nose is clean, fresh, and inviting, showcasing a refreshing balance between fruit, floral, and earthy elements.

The Palate

Arinto wines are known for their bone-dry, crisp profile and pronounced acidity, offering a refreshing and structured experience on the palate. Flavors lean heavily towards citrus—lemon and lime are common—often accompanied by subtle notes of white flowers and stone fruit, with a distinct mineral backbone. While typically light to medium-bodied, Arinto delivers a surprisingly rich texture for a high-acid white, creating excellent balance.
