Sauvignon Blanc Estate – 2020

Region: New Zealand


Estate grown grapes from organic and biodynamic vineyards are handpicked and transformed into artisan wines through gentle, traditional winemaking – wine of passion, grace and spirit. Acknowledging Seresin’s ongoing commitment to sound environmental practices as a winegrower, Seresin won the Marlborough District Council’s 2009 Marlborough Environment Award.

Winemaker's Notes

Showing restraint, elegance and purity of fruit. The 2020 Seresin Sauvignon Blanc brings together ripe aromas of
luscious tropical fruit, interlaced with savoury aromas. The palate is classically dry, textural and concentrated,
benefiting from a 10% addition of Semillon and extended aging on lees in neutral oak puncheons. Twine from 2020 will age beautifully and we will be drinking them for many years to come, remembering this unique vintage!
