I offer you 3 better alternatives to daily burping for fermentation.
Good: Latex balloon with a pinhole in it. Stretch the neck over the opening of the container, when uninflated the pinhole is too small to let contaminates in, as the off gassing inflates the balloon the pinhole expands and the gasses are released.
Pros- cheap, latex balloons are ubiquitous, not opening the container reduces the risk of infection
Cons- stretching and wear to balloon prevents reuse, risk of tearing or slipping allowing too much gas to escape and contaminates to enter the container, vigorous fermentation may fill balloon with liquid/foam or cause a blowout
Better: Airlock
Pros- easiest option, airlock will be designed for use with container with no modification or customisation, least interaction needed generally no action will needed during fermentation but occasionally airlock may need refilled, resistant to blowout and fluid/foam leakage
Cons- if there is a blowout it will be spectacular and potentially dangerous, can be difficult to find and expensive if not using one of a few standard types of fermentation containers,
Best: Blow off tube, run a tube from the opening of the container to a container of water with the fermenter end having an airtight seal and the water end submerged. Water level must be below the level of the liquid in the fermenter.
Pros- blowout proof, resistant to fluid/foam leakage and leakage is generally contained in the water container, all materials are available at hardware or craft stores and at most big box stores
Cons- creating an airtight seal can be tricky for non-standard containers, requires the most space and materials
