You can brew fermented hawthorn wine yourself. Wash and remove the core of hawthorn, mash it, add sugar and a little high-strength white wine, put it into a large-mouth glass bottle (jar) and cover it; place it in a warm place and ferment it at room temperature in autumn. Stir it every few days until the hawthorn pulp begins to change. It becomes fluffy, juice is secreted, bubbles are produced, and the sugar is converted into wine. After 1 to 2 months (extended time at low temperature), it is fermented, squeezed with gauze, removed and filtered, and hawthorn wine is made.
