Here is a trick to keep the odors down though. I like to use a blow-off tube in some sanitized water instead of an airlock. I like to place an erlenmeyer flask inside a box with packing peanuts and dryer sheets with a small hole in the top for the blow off tube to reach the flask. Then fill the flask with sanitized water. As the flask bubbles the dryer sheets along with the peanuts will cut down on the odor. Its not perfect, but it sure helps with any odors Like everyone else has said, it needs to vent.

However do not leave it open it will be ruined. You need to get the special brewing cork which has a little glass instrument on top which you put water in this seals it from germs and insects whilst letting the gases escape. gas needs to escape otherwise you will have an explosion.

Once the yeast gets going, you want to eliminate the oxygen and let the carbon dioxide build up. Most people use an airlock to accomplish this but a blow-off valve will work. If you try to make an air-tight fermenter, the carbon dioxide will blow the top right off. Initially, you want a lot of oxygen in your wort to stimulate the growth of the yeast.

Nope, you need whats called an airlock. A device that allows gas to escape the fermenter bucket but will not allow air into the hole. This is generally accomplished with water -- much like your toilet. You don't smell the sewer even though its connected without any valves.

GOOD LUCK!! they die in the presence of oxygen. they create carbon dioxide and alcohol (thanks, little yeast!). we keep them closed to keep oxygen away from them. when in wine , beer or any brewing process, the alcohol hits 15% the yeasties …well…die:(

It's been a long time since I brewed but I don't remember having to let the gas escape, but don't quote me on that.

If you don't let it out, it will get out on it's own. Kerboom! You'll just have to get used to the smell, I'm afraid. The gas (carbon dioxide) needs to escape.

It's not so much a problem with oxygen (the airspace inside the container is probably sufficient) as it is pressure form the gas.
