Weighted vs unweighted shaker tins

Note what is not on that list: the seal itself, and how well the drink chills. A weighted tin does not seal better than an unweighted one of the same geometry - the seal comes from the taper, which is a separate manufacturing question, and a badly cut weighted tin is worse than a well cut light one. Weight is about handling, not about sealing. Why shaker tins stick and leak is the page on the seal itself.

A weighted tin is not thicker all over. The extra mass sits in the base - a thickened, often cast heel that adds several ounces at the bottom of the tin and nowhere else. You can feel it immediately: set a weighted 28 oz tin on a counter and it has the dead stability of a glass tumbler rather than the tinny lightness of a cup.

That low centre of mass is the whole feature. It means a part-full tin does not tip when you knock it with a bar spoon, an empty tin does not slide when you set it down wet, and the tin stays vertical while you free-pour into it with the other hand. None of these sound like much individually. Together they are the difference between a tool that cooperates and one that needs watching.

The second effect is on breaking the seal. A sealed pair of tins is opened by striking the heel of your hand against the side of the large tin at the point where the small one is wedged, which shocks the two apart. A weighted base gives that strike a solid, inert object to work against instead of a flexing wall, which is why the break on a good weighted pair is a single confident tap rather than three nervous ones. How to shake a cocktail covers the motion, including the break.

There is one, and it is about speed. Unweighted tins are lighter, which means less work per shake and less fatigue across a long service, and that matters enormously in a busy room and not at all at home. A bartender making four hundred drinks in a night has a different relationship with four extra ounces in each hand than someone making two on a Friday.

They are also the tins of choice for throwing drinks - the technique of pouring a liquid in a long arc between two tins to aerate it. Throwing wants light tins you can hold at arm's length and control precisely, and weighted bases are dead mass in that motion. If you throw, you know this already.

And they are cheaper, which is a legitimate reason to buy anything. The problem is that unweighted tins are usually cheaper in two ways at once: less mass and thinner gauge. Thin-gauge steel dents on a dropped corner, and a dented tin is a tin that no longer seals, because the seal depends on two circular edges meeting cleanly. That failure mode is permanent and it is why a cheap pair of tins can become unusable in a month.

A tin and a pint glass - the original Boston shaker - is the other unweighted configuration, and it is a genuinely bad idea at home. Glass against metal is a worse seal, and the glass half breaks. If you want two-piece shaking, buy two tins.

Weighted or not, the standard pair is 18 oz and 28 oz, and that is not arbitrary. The 28 oz tin holds two drinks plus a full ice charge with room for the ice to actually move, which is what a shake is for. The 18 oz tin is both the lid and the vessel you build into, and the diameter difference between the two is what creates the wedge that seals them.

That means capacity is not where you economise. A smaller pair shakes one drink and crowds at two; a larger pair is awkward in a normal hand. If you regularly make four drinks at once, the answer is two 18/28 pairs rather than one enormous tin, which is also faster, because you can shake one while the other drains. What size cocktail shaker is the capacity question in full, and what size ice for a cocktail shaker covers the ice charge that fills it.

Both configurations need a separate strainer, because tins have no built-in one. That is a feature rather than an omission - a Hawthorne strains far better than anything built into a lid - but it is a second purchase, and it is worth factoring in when you compare a tin pair against a cobbler. Best cocktail strainers and how to use a Hawthorne strainer cover that half of the kit.

Weighted, in 18 and 28 oz, from a maker whose taper is known to be consistent. That is the Koriko pair as a default, the Barfly Deluxe set if you would rather spend less on the same idea, and the Leopold pair if the tins sit out where people see them. The weight is worth the few extra dollars because the handling benefits show up on every single drink, and because heavier gauge in the base is also the part that survives being dropped.

The one group we would steer away from tins entirely is people who do not actually want to learn the seal. Tins are a two-handed tool with a technique attached, and a weighted pair makes that technique easier rather than unnecessary. If the person making drinks in your house changes from night to night, a cobbler with the strainer in the lid is the better object, and nobody has to be shown how to break a seal. Boston vs cobbler shaker is that decision, and best cocktail shakers for beginners is where to start if tins feel like a step too far.

If you already own unweighted tins and they work, keep them. A pair that seals cleanly and breaks reliably is doing its job, and swapping to weighted is an upgrade in handling rather than a fix for a problem. Replace them when they dent, not before. Best weighted shaking tins is the roundup when that day comes.
