Really, all I want to know now is how @jimboothdesigns Daikon radish beer turned out and would be glad to see the recipe.

 

If someone is really concerned with using paint strainer bags, might I suggest: https://www.amazon.com/Durable-Reus...-1-spons&keywords=food+grade+nylon+mesh&psc=1

 

My PhD is in Natural Resources, with specializations in Biogeochemistry, Soil Science, and Ecology. I've had no formal experience with toxicology outside of killing some plants and some daphnia in high school and college laboratory sections I have taught. My academic background sometimes gives me insight into brewing chemistry and biology, but usually only in general ways that people who paid attention in high school would also understand. My little experience in toxicology has no bearing at all on my thoughts on this particular topic.

My thinking on the toxicology of nylon in brewing is actually guided by consulting a semi-anonymous professional on this very question. Have you ever listened to a the Basic Brewing Radio episodes with the dude who referred to himself as Toxicologist Paul? Through an email to James Spencer, as an intermediary, I put the question to Paul about using non-food grade nylon strainers and knee-high Nylon stockings. His response:

"We did review nylon back when we did the original podcasts, and there wasn't anything about nylon that was concerning. The hot water sanitization may have leached some compounds out of the nylons (which could explain the smell), but it probably did a REALLY thorough job of doing so, meaning there was probably very little left after this "preconditioning" step. If you then used them to dry hop and there was no off flavor or aroma, I wouldn't worry about them. My biggest concern would be off notes, you don't have anything to worry about in terms of toxicity (above ethanol of course).

The part about hot water sanitization refers to my practice of first sanitizing nylon in a boiling water bath and noting that it imparted an aroma to the water. That was part of my concern. My question was about dry hopping, but I think it points to both a potential problem and perhaps a solution regarding using nylon in the boil. It was the nylon stockings specifically that caused the weird aroma in the boiled water. So Paul was unconcerned. Why did I switch and stop using these nylon sources?

We'll always have problems coming to consensus on what it means to be safe, agreeing upon acceptable risks, and identifying causes behind everything that ails us. A couple persons close to me in my adult life were diagnosed with cancer, and during their respective recoveries (to date, both are cancer free, as far as I know), they looked for reasons. Hadn't they lived clean lives? What did they do to bring this on themselves? There were no obvious answers. Some combination of genetics and environmental exposure, to what? Both of my friends seemed to obsess over the possible answers. It's difficult for me to judge them, I didn't have cancer. But it is clear to me that many people have concerns along these lines, that stuff that they consumed that they weren't supposed to could cause them problems, unknown killers, lurking in the shadows. I do not want people to feel that way about my beer. I thought if some people knew I made beer with non-food grade products, they might have concerns. I could continue to fan those flames in order to save a few bucks, buying strainers from Menards or Sherwin Williams, instead of from the homebrew shop. What a penny pinching jerk I would be, now that I thought about it in these terms? While Toxicologist Paul made me feel OK about what I had been doing, I knew that not all of my friends would not be comfortable.

 

I see no reason why anyone would buy paint strainer bags when LHBS (or even Amazon) sell food grade brew bags that work just as well for like $10. I understand being frugal and stretching your money, but $10 for something you'll use for every brew is well worth it considering how expensive other aspects of this hobby are.

 

As a Daikon enthusiast, I'll be anxiously waiting your post and recipe.

 

Depending on what you are adding and what time you are adding those additions get (2) 300 mic baskets. Without getting into the chemistry of it and a confusing reply just get two baskets.
I use one and two baskets during a 25gal boil

 

Well I'm sold.

 

Can you explain this.I know that two beers are better then one but two baskets.
