Best Airlock for Fermenting and Brewing Beer (3-piece, S-shaped, More)
Any S-shaped airlock or 3-piece airlock works well for fermenting homebrew as long as it is properly sanitized, creates a tight seal with the fermenting vessel, and stays filled with sanitizing solution. Blow-off tubes can be utilized during active fermentation to avoid blowouts and then switched to either an S-shaped or 3-piece airlock later.
