In 1770, during his voyage to New Zealand, Captain James Cook would discover a stretch of land spanning New Zealand’s South Island, to the south of the Marlborough Sounds and north of Clifford Bay. Cook’s discovery coincided with regional flooding, which washed large amounts of sediment into the sea. Noticing the water’s opaque appearance, Cook christened the area Cloudy Bay. Cloudy Bay’s name was later officially altered to Te Koko-o-Kupe / Cloudy Bay, with the Māori name a nod to the early explorer Kupe. 215 years later, seasoned winemaker David Hohnen, convinced of Cloudy Bay’s potential to produce great wine, invested in the best land the region had to offer and established Cloudy Bay Winery. Now under the ownership of LVMH, many consider Cloudy Bay to be amongst the world’s best Sauvignon Blanc, including wine writer, George Taber. Defined in part by mouthfeel, Cloudy Bay Sauvignon Blanc also boasts intense, concentrated fruits, namely grapefruit, passionfruit, and guava. Joining via Zoom, following the recent launch of Cloudy Bay Sauvignon Blanc 2020, winemaker Daniel Sorrel told how chasing one particular thiol, 3MH, has come to help shape these defining characteristics. In this article, I examine thiols in more detail and explore more closely how Cloudy Bay and others hunt 3MH.
