From their initial planting, Alkoomi's area under vine expanded throughout the 1980s and 1990s, growth of vineyards has continued steadily, without sacrificing the naturally low yields which produce wines with a concentration of good flavour. Vines are all pruned by hand, harvesting occurs in the cool of morning, usually starting just after midnight to ensure grapes arrive at the winery in top condition. Exclusively estate grown Merlot and Cabernet are picked at healthy levels of Baume off several individual blocks. Parcels are treated to three days of cold soak for extraction of good colour and fine tannin, followed by a course of ferments and a year's maturation in French oak.
