I just got an email notice of Brew Toppers opening. I ran across them some time ago looking for places that made custom bottle caps. There's not too much on the site right now beyond their own selection of cap designs, but it's a start.Brew Toppers
Thanks PanzerBanana! We'll be adding lots of new designs as well as getting the custom bottle caps page finished up. One homebrewer to another --- thanks for your support!
Don't mention it! Anything to help promote a fun business!
Looks like these guys are gone, alas. Ordered some caps from them about six months ago, but now their website and twitter account are gone.
I order caps from http://www.bottlemark.com/
Had good experiences so far.
