The Alpha Domus winery was established by two generations of the Ham family. Their vision began in 1990 with the purchase of bare land in Hawke's Bay's Bridge Pa district and planting began in 1991. The name Alpha Domus was inspired by the first initial of each of the first names of the family members; Anthonius, Leonarda, Paulus, Henrikus and Anthonius (ALPHA); Domus is Latin for house. From their vineyards, the Alpha Domus produce world-class wines from a wide range of varietals including Cabernet Sauvignon, Cabernet Franc, Merlot, Malbec, Sauvignon Blanc and Semillon, Chardonnay, Viognier and Syrah. The commitment is to produce premium quality wines that are true to varietal character and are a reflection of their unique terroir. Their wines are single vineyard, estate grown, and made at the onsite winery.
The estate itself is in the vicinity of an historic airfield, important for training pilots throughout New Zealand's aviation history. The aircraft used was the de Havilland Tiger Moth which is depicted on the Alpha Domus labels. Henri has a passion for flying and holds a commercial pilot's license. The Tiger Moth also has connotations of romance, history, lasting design, beauty and passion; all elements found in great wine. The Tiger Moth and other colourful vintage planes are often seen in the skies above the vineyard.
