Cooking with wine and the type of wine being used for the cooking process is a question that is highly debatable, because the dish prepared clearly shows the wine that was used to make it. If the wine was a good quality one it’ll show and if it was a cheap low quality one, it’ll show!. Some people use drinking wines to cook while others use only cooking wines. Of course it must be remembered that a drinking wine can be used to cook, while keeping in mind that you are overspending where not required, but a cooking wine cannot be used to drink., Infact a cooking wine is salty and generally an inferior quality wine as compared to the drinking and is ok only for cooking and for nothing else.
Cooking with wine is as old as wine drinking itself. Infact it is assumed that originally fermented grape juices were used to prepare stews and casseroles and various other dishes. This fermented grape juice was accidently drunk by a member of a royal family, while he was in his kitchen and he liked it to the extent that a refined and better quality of the same juice was also created for drinking purposes from then on. That drinking juice later came to be known as drinking wine while the one that was used for cooking retained its name as a cooking wine.
As it was mentioned earlier, while purchasing a cooking wine keep in mind that whatever you buy will be reflected in the taste of the dish that is the end result. You can buy wine online. So a cheap quality cooking wine will give a bad tasting dish, and a connoisseur or a sommelier will easily be able to identify the type of wine that had gone into your dish! This does not mean that the higher priced a wine the better it is and the lower priced wine the cheaper It is.
