This is not living biological extract a compost extract not to be confused with putting a tea bag in water.I think its a myth that people are making bad teas........ If it smells bad, it's anaerobic. If it smells good, then it's aerobic. Pretty simple.
Here is what Teaming with Microbes has to say about Compost Extract:
Page 148-149
"Compost extract is what you get when you soak compost in water.....The end result is an anaerobic soup with perhaps a bit of aerobic activity on the surface. The loss of aerobic microbial diversity alone (not to mention the risk of it's containing anaerobic pathogens and alcohols) suggest that compost extracts are not worth the effort. We don't consider it safe or advisable to use them."
Teaming with Microbes on AACT's:
Continued from page 149
"Modern compost tea, on the other hand, are aerobic mixtures. If the tea is properly made, it is a concentrate of beneficial, aerobic microbes. The bacterial population, for example, grows from 1 billion in a teaspoon of compost to 4 billion in a teaspoon of actively aerated compost tea.
THen from the same chapter, page 161
"If you are still worried about E. coli
We find it hard to believe that e coli, an anaerobic organism, can be found in a properly aerated tea......Still, some folks remain concerned about the possibility of e coli growing in their teas.
An ACT is far superior to a compost extract for many reasons. Making a bad AACT is hard to do, keep the dissolved oxygen above 6 part per million and having a pump that supplies at least .05 cubic feet of air per minute, per gallon of water. Easy peasy.
If you got the proper tools and techniques to do it right, aact is excellent.
But if someone does not have a do meter and microscope here is way to do thing for less money and time and still get excellent result.
Bad aact. Not a myth at all. Bad compost not a myth either. Does not solely mean ecoli in the aact.
If you really want to make sure the aact is good use a microscope.
Going off smell alone does not mean you brewed a good tea.
There is not the same air in the medium the microbes then do not take hold in the medium.
