Maybe OP thinks we are trying to sell him something? Just click on the link. It's instructions on how to batch sparge using a home made cooler. Faster, cheaper method than what you are going to find on More Beer. I mean, you can certainly spend the money and still batch sparge on whatever you buy. And maybe you just have some extra money you want to spend. I get that, I love to spend money sometimes too. But at least check it out.
No, OP doesn't think that! I'm just leery of using any plastic with hot liquids. Considering the cooler companies tell you not to, I'd rather go SS.
I agree with you.
Though we're still far from a consensus on the safety of plastics (with so many different formulations), I think there are very legitimate concerns to consider with regard to heating plastics that are not formulated/tested for those temps.
Even prior to any real-world usage or heating at all, studies have found that compounds released are absorbed into our bodies and can impact our endocrine systems. Some of these compounds mimic estrogen and there are still a lot of unknowns regarding how people are actually affected by these chemicals.
I don't know about the rest of you, but I'm not looking for any increase in the man-boobs department.
We can all debate the effect on the human body of these compounds, but what's need are more long-term studies. What is pretty established is that you're sucking down plastic when you consume liquids that come into contact, especially at warmer temps.
Easy taste test: pour some water out of a non-refillable water jug into a glass. Don't need much of a trained palate to taste the plastic.
