Ice and Dilution
Ice doesn't just chill: it adds water, and that water is an ingredient. Understanding dilution is understanding why a drink tastes right.
Cold and water travel together
When you shake or stir, the ice melts, and that melting is what chills the drink. You cannot chill without diluting. A shaken drink typically ends up with around a quarter or more water; a stirred drink a little less.
That water softens the alcohol, opens aromas and knits flavors together. Too little dilution tastes harsh; too much tastes watery and flat.
Types of ice
Rule of thumb: more surface area, faster melting. Good, hard, dry ice gives you control.
- Standard cubes: for shaking and stirring.
- Large cube or sphere: for serving spirits and short drinks; melts slowly.
- Crushed or pebble: for juleps, swizzles and tropical drinks; dilutes fast on purpose.
- Spear: for highballs; helps preserve carbonation.
Wet ice vs. dry ice
Ice that has sat in the well is coated in water and over-dilutes from the first second. Ice straight from the freezer, several degrees below zero, chills more with less water. That's why the same recipe drifts through a shift.
