The article presents the results of the quality assessment of wine from Rowan businesses. The expediency of using Rowan berries for wine production is proved. The results of the study of consumer demand. The technological scheme of production is resulted. The conducted research allowed to establish that the development of wine technology from Kamchatka raw materials is relevant, since most respondents who buy wine expressed their willingness to buy wine from Rowan berries.

Found that wine made from Rowan has a brown color with extracted fruit flavors, moderate alcohol content, balanced sweetness and velvety tannins. The taste of wine is characterized as fresh, moderate and harmonious, with a long pleasant aftertaste. According to chemical indicators (volume fraction of ethyl alcohol in table fruit wines, mass concentration of sugars, mass concentration of titratable acids in terms of malic acid, mass concentration of residual extract) wine fully complies with the requirements of the standard for table wines semidry. Changes in the content of vitamin C in wine during storage are considered. It is shown that the wine contains a significant amount of vitamin C.
