🍾 100 Pack of Grolsch Gaskets: High Pressure Rubber Seals for Swing Top Bottles Review

Our second-fermented water kefir ginger beer develops a decent head of foam. However, this is not a problem with these full-surface silicone seals. We switched all our bottles to it.

With these seals, after a short second fermentation, the bottles open with a powerful bang, whereas before it was a barely audible "Fu" when the CO2 escaped through cheap seals. In our tropical climate, the…

I'm sorry to say the shims weren't enough, not because of some shim issues, but the other bottles are just too loose and the shims alone won't fix them. However, I was very impressed with not one, but two consecutive emails. The first gave me advice on how to
