Have you tried breastmilk?
Both me and my husband have tasted Avery's. It was so funny to see my husband taste it. You would've thought I asked him to drink battery acid or something! He put a little drop on the end of his pink and slowly put it on his tongue, making faced the whole time. Then he said it tasted a little bit like milk at the bottom of the cereal bowl - It's sweet!
We tasted it because I wanted to know what it should taste like fresh, so we'd no if it ever went bad. My husband will usually give the bottle if she ever needs one so I wanted him to know too.
When it's starting to go bad there is a really weird, bitter aftertaste. It kind of reminded me of dirt, but a little bit sour. You don't need to taste much to know it's bad. Just a drop or so.
I have tried my own milk but I don't see the point in drinking it, it seems counter productive since I had to burn calories to make it.
i have tasted it before ( unwillingly), it is very sweet !
