Ice wine, also known as ice wine, was first produced in Germany. 1794 Frank region of northern Germany, a fortuitous change in the weather, there was a rare freeze, so that the grapes in the field are frozen, the farmers had no choice but to use the juice of these frozen grapes, to ice brewing, and accidentally found that this wine is different from the general wine, the quality of a unique, unique characteristics, and since then, deliberately kept the Since then, this production method has been deliberately preserved and continuously improved to form the special technology of ice wine, which has a history of more than 200 years. The first requirement for the production of ice wine is the raw material of grapes, and the quality of the raw material is limited by the influence of natural conditions. The Quebec region of Canada is characterized by a cold climate that lasts for a long time, which gives it the natural conditions to produce icewine. This has led to the development of ice wine, which can be said to have been first produced in Germany but originated in Canada. At present, Germany, Austria and Canada have ice wine products, but the Niagara region of Ontario, Canada is known as the world's most famous ice wine production area.
Wine made from grapes that have been naturally frozen on the vine at temperatures below minus 6 degrees Celsius. The grapes are pressed when they are frozen solid and a small amount of concentrated juice is released. This juice is slowly fermented and bottled after several months. The outside temperature must be kept below -6°C during the pressing process.
