I decided to scoot by the salvation army after work yesterday, where I picked up two badass one gallon picnic jugs for $2 each.
These seem perfect for making experimental one gallon batches of alcohol! I've brewed several batches of beer in 5-gallon plastic, these could be just like my fermenter and bottling bucket but on a smaller scale. The spigot on the orange one is on top, I imagine I'll affix a balloon with holes in it over the spigot for a makeshift airlock. The red one has the spigot at the bottom.
The only problem is, these jugs are not airtight at the moment. Water comes out from under the cap on both if the jugs are turned upside down. Any advice on making them airtight? The only idea I had was to trace the cap on a sheet of foam packing material and place the circle under the cap to create a seal.
Also, what would happen if I did create a tight enough seal and at bottling time on my current brew I just siphoned a gallon in to the red jug? In two weeks would the beer be fully carbonated? The spigot is rather high on the bucket so sediment probably wouldn't be a problem.
