I have concerns over why our beers are not carbonating properly. One suggestion was to check and make sure the bottles are sealed properly. What might be a good way to do this?
A quick check would be to stretch a rubber balloon over the neck of your bottle after capping. If the cap is not sealed the balloon will slowly inflate.
If you're using a butterfly capper, check to make sure you're pressing hard enough. There should be a slight ring-shaped indentation in the cap after capping a bottle.
An easy way to check once they're capped is to simply store a few upside down. If there's a leak, the gas will bring some beer with it as it leaks out the cap.
I've heard that storing beer bottles tipped or upside down can cause strange tastes due to the cap deteriorating. Nov 14, 2010 at 17:10
There are Go / No-go guages that are used in industry for online checks to ensure a tight crimp on a crown. Failing this immerssion on a a water bath will quickly show if you have leakers. The folks who make the crowns will provide the data on what a tight crimp should be. hope this helps
