I've bought a new bottle capper (two-handled hand held capper) and have tried it on a number of different types of (empty) beer bottles.
It works okay, but I've noticed that none of the caps seem to be as tight on the bottle as they are on store bought beer bottles. Eg, its too tight to be pulled off, but I can relatively easily twist the cap around in place on the bottle. Store bought bottle caps seem to be too tight to do this.
Will the beer carbonate properly if it's not airtight?
