Which type of wine is permitted even if it has been heated?

Mevushal wine is a type of wine that has undergone a process of heating, which makes it permissible for consumption by individuals who observe kosher dietary laws, even if it has been handled by someone who is not Jewish. This heating process can include pasteurization or boiling and serves to maintain the wine's kosher status.

In the context of kosher laws, non-mevushal wine has restrictions regarding who can handle it, as it must be managed only by Jews for it to remain kosher. Since mevushal wine has been heated, it can be enjoyed at gatherings where there might be mixed company, including those who may not be Jewish, without compromising its kosher status. This distinction is crucial for understanding kosher dietary practices and the social dynamics around food and wine in Jewish culture.
