The latest edition of "Dirt" made me think of a question I've been pondering, so I figured I'd finally post it.

In the basic 5 gallon brewer using a "tea bag", it is sometimes recommended to take the tea bag out after 6-8 hours, then continue to aerate for another 16-20 hours.
I know that this setup and procedure (see http://tinyurl.com/2w8235 for specifics) has produced very good results.

The question: Why remove the tea bag partway through? I know a lot of reasons for and against using a bag at all, but why for only part of the brewing time?

That was my website you linked to but Bruce Deuley was the original author of the plans. So I wrote to Bruce about your question. Here is his reply to me.

Hi David.
After doing lots of tea brewing, it was established that, at least in warmer weather, there was no benefit to leaving the compost in the mix and it may actually be detrimental to the overall brew by over-populating the tea with too much bacteria causing it to go anerobic before any fungi had a chance to grow. bacteria multiply much faster than do fungi and were using up too much of the O2 not leaving any for some fungi....make sense?

I have now made a very simple 25 gallon system that I will be testing this spring and will let you know what my numbers look like.

Thanks, David. I was hoping you'd peek in here.

I had thought that most of the fungi in teas came from mechanical extraction because they are just too slow to significantly multiply within the brew over a 24 - 36 hour timeframe. But since he tested it and Ingham qualified it, I'll go along with it.

ps - I wrote Bruce Deuley this afternoon, before seeing your post. I hope he doesn't mind getting hit twice with the same question.
