I had some wine leftover and wanted to put them in the freezer to use it at a later point for baking or cooking. So I just poured it into a freezer bag.
Today, I noticed that the bag is not frozen solid (that's expected because of the lower melting point of alcohol), but unfortunately also leaking. But not really leaking wine - more like a reddish water?
So I took it out and filled the wine into a hard plastic box container. Afterwards I inspected the bag: it has no holes. I filled it with water and there was no leaking.
What's going on here? Are freezer bags not safe to store alcohol in? The bag is made from polyethylene (PE).
