Why this cocktail shaker earns its place
Shaking is not just chilling. It chills, dilutes and aerates in one action, and the dilution is part of the recipe rather than a side effect — a sour that has not been shaken hard enough arrives sharp and hot, tasting of raw spirit. What makes that work is headroom. Ice has to travel the length of the tin and hit the end to break up and do its work, and a shaker packed to the lid does not shake, it just gets shoved about. At 750 ml there is room to load ice properly and still have the space above it, which is why the capacity is a working spec and not a marketing one. It also means a second drink of the same build can go in alongside the first when an order comes in a pair.
Stainless steel is what the trade settled on. It pulls cold through fast enough that the outside frosts while the drink is coming together, which gives the bartender a timer they do not have to count, and it goes properly painful in the hand at about the point the drink is done. It absorbs nothing, so a rinse between rounds clears citrus, bitters and dairy, and it takes being dropped on a wet bar mat night after night. The silver finish shows water spotting if it is left standing wet, so shakers get rinsed, dried and stored open rather than sealed with moisture inside them.
