It takes about 24-36 hours to make compost tea. If you store it any longer than that, your concoction is in danger of collecting some unfriendly bacteria like salmonella and E. coli.
The microbes created will use up all the oxygen provided creating anaerobic conditions. This condition increases the likelihood of viruses, mold, and bacteria thriving.
Compost tea is simply throwing your ingredients into a bucket of water, letting it sit, and voila you have the tea ready in several hours.
The second tea known as aerated or aerobic compost tea needs oxygen and agitation. The regular compost tea is mixed with more oxygen than in the compost tea. It requires a little more work, with a lot less smell.
