I really like to use white wine vinegar, nice sweet flavor to add on the chinense chile flavors.
I've tried the red wine vinegar but I think its a very sweet flavor, kinda over powering if you use to much.
apple cider vinegar is good, alot better than the harsh tasting basic white vinegar.
others here have said that other speciality vinegars taste great.
if you dont have the options of other vinegars besides the basic white vinegar, try to use a little more lime or lemon juice than the basic vinegar to give it a better taste.
