I have a recipe that calls for a cup of dry white wine. Not being a white wine drinker, I'm not sure......?

"Dry" means low in sugar. Go with Savignion Blanc or Pinot Gris/Grigio. You should be able to find small bottles at liquor stores, either in 4 packs roughly the size of beer bottles or even small singles.

I use white dry wine for cooking, i don't drink it, i only drink red wine. So i put the bottle of white wine in the fridge for the next time i will use it, i save it in the fridge sometimes for 3 months.

I don't use expensive wines for cooking but i use organic wines

You can use Chardonnay or Sherry. I prefer cooking with Sherry wine, when I use drinking wine I typically get a fruity wine taste to my recipes and I personally dont like that. But you can always go to the liquore store and ask them, they can help you.

They say you can substitute white vinegar for white wine, but I am unsure about that in large amounts like a cup full.,,just an idea OR you can use a red wine, if you drink wine..IF you have an ALDI's store near you ,as they sell wine in the $5.00 range. Use what you need and feed the rest to your lawn or garden for the acidic nutrients. I hope this helps..

You can get a small bottle of white cooking wine and not worry about leftovers. If you ask me, the cheaper wines are better to cook with, for some reason they add more flavor.

Sauvignon Blanc or a Riesling are other dry whites you could try. You don't need to buy "top of the range" for cooking but I would suggest a good quality wine if you can pick it up cheaply.

If you have left-over wine, freeze it in your ice-cube tray, once frozen save the cubes in ziplock bags in your deepfreeze, you can always use a block or two in soups, casseroles, sauces etc.

Chardonnay is a dry white wine - you may be able to get half bottles.

Use non-alcoholic grape juice, it's fabulous, use leftovers in drinks mixed mixed with orange juice and mineral water, great summer drink. Cook it down as you would a general wine, works great. If you require brandy, use some apple juice. Good luck and happy cooking
