In my first bottling, I decided I wanted to try using half normal reused glass bottles with new bottle caps and half reused Grolsch beer bottles.
Probably the worst part of the process was having to drink the Grolsch beers. They are horrible and half of them were skunky (could it be because of the green bottle versus brown?), and the other half just weren't good at all. What I noticed was that all of the normal bottles that I cleaned and sanitized tasted fine, but the Grolsch bottles tasted skunky, but only at the top of the bottle. Once I had been drinking a little bit further into the bottle, the skunkiness went away. Before I bottled it, it was hard to make sure the cap was fully sanitized. I closed the bottle with the sanitizer in it, and tipped the sanitized solution toward the cap.
Has anyone else noticed this problem with using Grolsch beer bottles? Are they just not a very good bottle to use? I think after my experience, I would not recommend them.
