The belief that the vineyard is the key to a great wine is at the core of Walnut Block. Labor intensive, organic vineyard methods produce consistent, exceptional fruit quality; the use of traditional winemaking techniques and attention to preserving delicate flavors & aromas. Among the vines stands the region’s oldest walnut tree, and to pay homage, the Collectables label depicts an adaptation of the 1898 Kiwi New Zealand stamp. Both the planting of the tree and the release of the stamp occurred over 100 years ago and celebrate the unique Kiwi history and roots of Walnut Block. The 2023 vintage was phenomenal in Marlborough; while there was plenty of rain, it was more evenly spread across the growing season than in 2022. Plus, protracted early-season flowering conditions led to fewer berries per cluster, and thus more open bunches that did not suffer from rot as much as in 2022. Cold nights were also crucial for retaining striking acidity this vintage.

The fruit is grown on 3 cane VSP trellises. Light leaf removal is performed to give plenty of sunlight for thiol production and airflow to ensure healthy fruit. The yields are controlled through shoot thinning. Harvest takes place during the cool of night to maintain freshness. The grapes are de-stemmed and pressed, then slowly fermented in stainless steel at a cool temperature using carefully selected yeast. Extended yeast lees contact adds weight and texture to the palate. After three months in tank the wine is racked, lightly fined and filtered and hit with sulfur dioxide then bottled.
