TapIt Cap
Tired of your growlers going flat before you have a chance to finish them? Well then drink faster! Just kidding — you should look into a TapIt Cap ($45). This clever new gadget fits over your growler's opening, ensuring that the beer in your growler stays fresh, carbonated, and ready to drink. Thanks to a slot that accepts standard-sized CO2 canisters and a built-in tap and tap handle, it turns your growler into a handheld keg and tap, perfect for barbecues, social gatherings, or anytime you want fresh, draught craft beer.
