I just found out that many wines contain these ingredients. They are used in the fining process. This removes sediment from the wine. They do not have to disclose the ingredients they use in the US. I'm sure most of us who are BFing aren't drinking a lot, but still important to know.
I didn't check about eggs, since my DS isn't allergic, but Yellow Tail reds and two buck chuck reds are casein free.
