More and more craft brewers have switched from twist-off caps to pry-off style caps including Sierra Nevada and Summit Brewing. Pry-off caps offer a better seal, online keeping your precious craft brew safer from harmful oxygen leaking in. The downside to these pry-off caps is that one has to remember to carry a bottle opener with them everywhere since you never know when you might need to tip back a beer with friends. That problem has been solved with the EasyOpen design by Gonglue Jiang. A small tab on the bottle cap makes opening easy while offering the same advantages of a normal pry-off style bottle cap. Pretty cools idea from a Harvard University grad.
