How to use a bottle opener without damaging the bottle (classic, lever, wall-mounted, rocket)

Knowing how to use a bottle opener seems obvious, until the day the cap bends without coming off, the tool slips and the bottle neck loses a chip of glass. Each model has its own move: the classic one levers, the Capblast snaps down, the wall-mounted one pulls downwards, and the Beer Mortar gets struck while aimed at the sky. Here's the right move for each, then the mistakes that damage the bottle.

In short: hook the edge of the cap, push against its top, never against the glass, and lift with a firm but steady motion. Hold the bottle by the neck, upright, on a stable surface. If the cap resists, turn the bottle a quarter turn and try again rather than forcing it.

The principle: a hook, a fulcrum, a lever

A beer cap is a thin metal sheet crimped around the bottle neck: its teeth (traditionally 21, as told in our short history of the bottle cap) are folded under the lip of the glass. To open it, a bottle opener does two things at once. One part hooks the edge of the cap from below. Another part pushes against the top of the cap. As you lift the handle, you bend the cap at that point, the teeth come loose and the whole cap lets go.

The fulcrum has to be the cap, not the glass. That's the whole difference between a bottle opener and a knife or a table edge: the proper tool pushes on the metal, the improvised one often pushes on the neck. A neck that takes the strain can chip.

The classic bottle opener: step by step

This is the flat opener in the photo above, the one from the kitchen drawer or the keyring. It works in four steps.

1. 1Hold the bottle by the neck, upright, or stand it on a stable table. Thumb and index finger just below the cap give the best control.
2. 2Slide the hook under the edge of the cap, and lay the flat part of the opener on top of the cap.
3. 3Lift the handle with a firm but steady motion, no jerking. The cap bends where the hook is and comes loose.
4. 4If it resists, turn the bottle a quarter turn, put the hook on another part of the edge and try again. Two small lifts beat one big yank.

The waiter's friend often has an opener on the corkscrew shank: same principle, same move. A keychain opener works the same way with a shorter handle; our keychain bottle opener guide helps you pick a shape that gives enough leverage.

The lever bottle opener: place it, push down

With a lever opener, your hand no longer has to find the angle: the mechanism does that. The Capblast sits on the bottle neck, you push the lever down with a sharp move, and the cap pops off. Its product page describes it as compact and light, to slip into a pocket or clip to your keys, and compatible with standard caps (330 ml and 355 ml bottles).

The move is simple, but the cap does fly: point the bottle away from faces and screens before pushing the lever, and keep the opener out of children's reach.

The wall-mounted bottle opener: pull down

On a wall-mounted opener, the wall provides the fulcrum. Hold the bottle by the neck, slide the edge of the cap under the hook, and lower the bottom of the bottle in a steady motion. The cap drops: put a tray or box underneath, or it'll roll under the nearest cabinet.

Mounted too high or too low, it forces you to tilt the bottle and the foam spills over. Height, surface and cap collection are covered in wall-mounted or tabletop bottle opener.

The rocket bottle opener: aim at the sky, strike

The Beer Mortar works differently: no lever to handle, an internal spring does the work. Its How it works page sums it up in three steps.

1. 1Stand the bottle on the floor or a stable table, with clear space above: no ceiling light, no chandelier, nobody in the line of fire.
2. 2Place the mortar flat on the cap, sleeve facing up, and aim at the sky. A tilted mortar cuts the range.
3. 3Strike the piston sharply with your palm. The cap takes off up to about 3 metres with a loud PCHHHIT.

Never aim at a person, an animal or a screen: a launched cap can hurt at short range. Keep the mortar out of children's reach. The mechanism is explained in detail in how the beer mortar works.

Mistakes that damage the bottle (or your fingers)

• Pushing against the glass: with a knife, a spoon or a table edge, the strain often goes through the neck. That's how it chips.
• Yanking before the hook is engaged: the tool slips, the cap bends on one side and stays crimped. Move the hook further along the edge and lift again.
• Holding the bottle by the body: it tips during the move. The neck gives a safer grip.
• Opening a bottle that has just been shaken: the foam gushes out. Let it stand upright for a few moments.
• Leaving caps lying around: their edges are sharp. A box within reach saves your feet, and they can go into craft projects, as in what to do with beer bottle caps.

A cap that's bent after opening is normal: the metal deforms to let go. A chipped neck, on the other hand, is not one to drink from, because a shard of glass may have fallen into the bottle. Pour it down the sink and open another one if you still feel like it.

No bottle opener at hand?

Lighter, spoon, another bottle: the fallback methods and their precautions are gathered in how to open a beer without a bottle opener. To compare every type of opener, from the most discreet to the most spectacular, see our bottle opener comparison, and for the model with a pistol-style grip, the gun bottle opener explained.

A good technique is there to open a bottle cleanly, not to open more of them. Keep water and alcohol-free drinks on the table too. Selling alcohol to minors is prohibited in France. Alcohol abuse is dangerous for your health; please drink responsibly.
