The Ah-So wine opener: how to use it, and when you need one
The two-prong opener that lifts a fragile old cork out whole. How it works, how to use it step by step, when a corkscrew is better, and the Ah-So versus the Durand.

The short answer: an Ah-So is a cork puller with two thin metal prongs instead of a screw. The prongs slide down between the cork and the glass, grip the cork from the outside and lift it out whole. It is the tool for old bottles, when the cork has gone soft and a corkscrew would tear it apart.
Why an old cork needs a different tool
A corkscrew works from the inside: it drills into the cork and pulls. That is fine for a young, firm cork. After years in bottle, a cork can turn soft and crumbly. The screw tears straight through it, and you are left fishing crumbs out of a wine you waited a decade to open. The Ah-So never pierces the cork. It squeezes it from the sides, so even a fragile cork tends to come out in one piece.
How to use an Ah-So, step by step
- Cut the foil below the lip of the bottle and wipe the top of the cork clean.
- Long prong first. Push the longer prong a little way down between the cork and the glass. Never push both prongs in at the same time.
- Then the short prong, on the opposite side.
- Rock it down. Rock the handle gently from side to side, moving the prongs down a little at a time, until the handle rests on top of the cork.
- Twist before you pull. Turn the handle without pulling, to free the cork from the glass.
- Twist and pull together, slowly, and the cork rises out whole.
Go slowly. The aim is a whole cork, not a fast one. If the cork starts to slide down into the bottle, stop: a loose old cork is a job for a Durand (below).
When to use it, and when not
- Use it for bottles with real age, roughly six years and more, and any cork that looks dark, wet or crumbly at the top.
- Use a waiter's friend for young wines. A firm, tight cork is hard to get the prongs into, and a corkscrew is quicker.
- Practise on everyday bottles first, so the technique is in your hands before you meet a precious one.
The Ah-So I make, and the one for collectors
For most wine lovers
SOMM DIGI Ah-So Wine Opener
My own opener. Two prongs that slide down either side of the cork and lift it out whole, made for bottles six years and older. It comes with a gift wine disc for drip-free pours.
For serious old-wine collectors
The Durand
A corkscrew and an Ah-So used together: the screw goes in first to hold the cork steady, then the prongs slide down around it. Created by the collector Mark Taylor and named after his mentor, the sommelier Yves Durand. The tool for very old, very fragile corks, at a premium price.

A little history, and that name
The two-prong cork puller is old. A US patent for one was granted on 4 March 1879 to Lucian C. Mumford of San Francisco, for blades that slide down either side of the cork and clamp it. Nobody knows for sure where the name Ah-So comes from. The usual story is the German “ach so!”, roughly “oh, I see!”, the moment it clicks how it works. Its old nickname is the butler's friend: because it leaves no hole in the cork, the story goes, a butler could sip the wine and put the cork back unnoticed. For the rest of the story, read the history of the wine opener.
Questions people ask
What is an Ah-So wine opener used for?
For opening older bottles whose corks have gone soft or crumbly. It lifts the cork out whole instead of drilling through it.
Can I use an Ah-So on any bottle?
You can, but on young, tight corks it is harder work than a corkscrew. Keep it for wines with some age.
What if the cork falls into the bottle?
Don't panic. Decant the wine off the cork into a carafe through a fine strainer. Next time, with a loose cork, use a Durand, which holds the cork with a screw while the prongs go in.
Can you put the cork back with an Ah-So?
Yes. Because the cork comes out whole, you can grip it with the prongs and ease it back into the neck.
