Preventing Debris from falling into the boil

[sgillespie]

Hello: I just bought an outdoor propane burner from Walmart. When I was testing it out (making sure it could boil 5G, etc.), I noticed that it had debris, flies, and things that I generally did not want in my beer. How do you all prevent that?

The obvious answer would be to cover the pot while its boiling. However, I always thought it best to take off the lid for the boil.

The next thing that came to me was to cover the pot with a grain bag. If I did that, I'd be afraid of melting my grain bag? Any ideas?

Thanks

When its boiling, not many bugs are attracted to the pot. Besides, if your going all grain there is all kinds of foreign material already in the grain. Not a lot.......but its there. Unless you have swarms flying around you're pot......don't worry.

I boil outside all the time, and I've really never had anything, not even a leaf fall in my kettles. And bugs don't even tend to want to get too close to the boiling wort. Maybe the steam and heat or hops has something to do with it, but besides a few rain drops I've never had a care. Besides if something did fall it, it would be steralized, just like how we stick our wort chiller in for 15 minutes to kill anything on it before the wort got too cool.

If you look at pics from yesterday's brewlapalooza yesterday you'll see we got pleny of brewing (2 5 gallon batches and 5 1 gallon meads, with no problems.
