Golubok is an interspecific hybrid of Severnyy X pollen from different varieties: 40 Let Oktyabrya, Odesskiy Ranniy and No 1-17-54 (Alicante Bouschet and Cabernet Sauvignon).
[1] It requires protection from birds earlier than others, and appears susceptible to bunch rot in the Puget Sound AVA.
[2] A study of recently introduced cultivars, selections, and clones (predominantly from cool climate areas) was conducted at Washington State University's Mount Vernon NWREC in 2000, which showed that Golubok performed well at 1900 growing degree days (GDD) and below.
[8] The grapes have a deep color that appears black and a rich flavor coming from its darkly pigmented pulp and skin.
It is typically fermented in stainless steel casks, and is blended with other grapes such as Cabernet Sauvignon more often than it is used to produce monovarietal wines.
