Located in the Southern Valleys on rolling Loess clay hills, Auntsfield’s estate-grown Sauvignon Blanc has a deeper, riper, more intriguing flavor profile than many of the vineyards located on the valley floor. The 2025 vintage in Marlborough was characterized by excellent yields and a warm dry long summer. Regular winter rainfall and a warm late spring encouraged optimal canopy growth and fruit set. Summer was dry but stayed relatively cool resulting in healthy vines with no disease or water stress. Many hours were spent throughout the season reducing yields to optimal levels. There was a slow progression into autumn with a long, drawn-out ripening period where the fruit reached optimum ripeness in perfect harvest conditions.
The fruit was hand-harvested during cool evenings and fermented at low temperatures with native (10%) and industrial (90%) yeast in stainless steel tanks. After fermentation, the wine underwent an extended period of lees contact for six weeks, adding texture and length. The wine was then bottled with a vegan fining, cross-flow filtration, and dose of sulfur.
