Description

technical field [0001] The invention relates to a berry ice wine and a preparation method thereof. Background technique [0002] Ice wine: from ice wine, ice wine is also called ice fruit wine, the word comes from the German "Eiswein". In the winter of 1794, an early frost suddenly hit the Frank region of Germany. The grapes of that year seemed to be destroyed. The winegrowers bit the bullet and squeezed the half-frozen grapes to make wine, and they actually produced a wine that was different from other wines. unique flavor. So they called this wine ice wine. Generally, grapes used to make wine contain about 80% water. The grapes harvested late are obviously dehydrated after being beaten by wind and frost, and their sugar content and acidity are greatly increased. Therefore, the ice fruit wine made from this grape is naturally sweet and mellow. Since then, ice wine has become a specialty of Germany. In Germany, ice wine (Eiswein) belongs to the highest level of high-qual...
