After mapping and separating the Alkina vineyard in Greenock into tiny patches known as polygons, based on varying geologies, the winemaking team has made tiny amounts from the most distinctive of them in what they deem the results of intense research and extreme commitment. The prices of their Polygon wines reflect this and their rarity. From a limestone-based section of just 200 grenache vines, this is made in much the same manner as all the Alkina wines, here 50% whole bunch fermented in one concrete tulip before 15 months of maturation in 10-year-old barrels. Delightfully red-fruit juicy, subtly spiced with a surround of chalky tannins, imbued with energy, the balance of all involved elements delivers a purity of intent as well as fabulous drinking pleasure.
