wine picnic bags are very useful for carrying your precious wine bottles. I’m very clumsy and keep dropping everything everywhere. My friends even call me “butter fingers” for this. Not once or twice but many times I’ve dropped the wine bottle. I love wine and cannot forego having it especially on a picnic. And every time I dropped a bottle we had to run back into town and get a new bottle, this wasted a lot of time and money. My friend had these wine bags and ordered them for me. Now because I have it in the bag it does not break even if it falls because of the insulation.
