Flash Pasteurization

Flash Pasteurization is a method of heating wine to a temperature acceptable for making Mevushal varieties that's become very popular in recent years. Basically, the process heats the wine to the temperature necessary to make it kosher, but avoids simmering or boiling the grapes.

The main issue most people have with the traditional Mevushal process is that heating the wine to such high temperatures is harmful to the wines integrity and flavor. Flash pasteurization has become the number one way to sort of skirt the problem - heating the wine without ruining the flavor. The process may have helped to make kosher wine a lot more palatable, but the idea is still being met with some resistance by Jews whom associate kosher wine with the more traditional pinkish, tea colored varieties.
