Cooking wine is awful stuff. You are better off using no wine at all.
Wherever wine is sold in your state, look for the individual serving white wine bottles. They are sold in four packs and often as loose singles in a discount bin. Sine you are not a drinker, these will minimize waste. You can freeze any leftover from an opened bottle for later use.
For the type of wine, look for sauvignon blanc, pinot gris or pinot grigio. Chardonnay is also a possibility but I recommend you avoid chardonnays aged in oak.
