Well, she seems to have got this much right "With cheap beer – you are not just getting a cheap buzz, you are getting the worst of the worst." Ok.
After that, it just seems to be a mindless rant. Isinglass has been around how long? It and gelatin are pretty natural ingredients, I would think. The beaver anus doesn't make much sense to me. I remember years and years ago Wendy's fighting off some story that they used earth worms in their burger versus the 100% beef they claimed. Turned out earthworms are incredibly expensive compared to beef; so, it just doesn't make sense. Now, I don't claim to know the going rate for a beaver anus, but I'll bet actual berries are cheaper.
