Vineyards which produce fruit exhibiting the most exuberant regional expressions are located at the cooler western parts of Wairau Valley. The free draining soils and extended ripening conditions suit the style of Sauvignon Blanc which is Momo. Over the years, a delightful character of citrus has developed in the grapes grown at this end of the valley. Momo expresses the endowments of a unique mesoclime, a stylish young white exhibiting all the ripe lychee, gooseberry and passionfruit elements which are the hallmarks of Marlborough Sauvignon Blanc.

Seresin Estate are very close to the land and soils which grow their fruit. Adherance to principles of environmental sustainability means organically grown, hand tended grapes, raised on a cornerstone of working in harmony with nature. The Sauvignon Blanc is picked in the late evening and early morning, at the close of the long Wairau Valley summer, to ensure the fruit comes to the winery cool. Minimal intervention allows the layers of flavour to evolve, the grapes are quickly pressed to capture the personality of the locality. The juice is fermented at a lower temperature, again to retain these characters, then allowed time sitting on yeast lees to give greater palate depth and complexity.
