The first sip of a freshly opened beer is the closest that anyone can get to understanding a brew master’s true intention. The fragrance of the hops, the tingle of the carbonation and the depth of the flavor consume your senses — it is almost as if the tipple is whispering brewery secrets into your taste buds. This fleeting moment is the wedding of wet to whistle and, for the true beer enthusiast, the honeymoon should last as long as possible.

If you’re sitting with a 12-ounce of Coors, you probably won’t need to pop open the top then close it back up before finishing. But the size of regular beer bottles are getting larger, and craft beers, lambics and ciders are sometimes sized for more than one sitting. This bottle opener and resealer is a great pocket-sized gadget to have in order to make sure that not a drop of that dear brew goes to waste.

Once the resealer is slid into place, the seal is tight enough that none of the liquid will spill even if tipped completely upside down.

Use & Care

Works on 26 mm caps (U.S. standard), 29 mm (craft and large European) beer bottles, and sparkling wine bottles. In the event that a twist-off cap becomes stuck or impossible to open, it can even be used to pry those caps off as well.

The resealing function is what sets this gadget apart - and can also be used for a wide range of pop-cap bottles. Simply flip over the implement and, using the metal guides to grip the rim at the top of the bottle, slide the rubbery panel over the opening to ensure a tight seal over the beverage, preventing the contents from going stale or spilling when turned over.

Very little maintenance is required to keep this opener in pristine shape for a long time to come. A simple rinse and dry every so often is enough to keep it shiny and to prevent a build-up of beer on the rubbery seal.

Production & Design

At 3.5 inches long, this will fit into any pocket, cooler or backpack and is ideal for every outting, from fishing trips in the wilderness to watching the game on the couch. The opener is made of chrome-plated metal and is engraved with basic instructions for use, giving the gadget a vintage "bare essentials" feel.

On the sealing side, the metal guides and the elasticity of the material ensures that the tightest possible grip is achieved without having to exert too much effort. Once you have the resealer in place, you can tip the bottle upside down and nary a drop will spill.
