A GENERAL GUIDE
Clear ice for coffee.
Cold brew, latte, tonic.
Speciality coffee is sensitive. A barista picks the bean, dials the grind, calibrates the extraction, then pours the drink. If the ice in the glass carries freezer odours or dissolved minerals, the cup tastes like the freezer instead of the bean. Below is a general guide to using clear ice for coffee, written from a Malaysian supplier's point of view.
Why coffee notices.
Coffee is the easiest drink to ruin with bad ice. A bean carries hundreds of flavour compounds at low concentration. When ice melts into the drink, anything in that ice ends up alongside the bean's profile. Freezer ice usually contains chlorine, calcium, magnesium, and absorbed food odours. Clear ice carries essentially none of those. The cup tastes closer to how it was built.
Cold brew.
Cold brew is concentrated, smooth, low-acid. Pour over a tall clear cylinder (4 cm by 11 cm). The cylinder chills the pour evenly, fits standard cold brew glassware, and lasts the duration of the drink without thinning the brew. See the cylinder →
Iced latte.
A 5 cm clear cube in a standard latte glass. The cube chills the milk and espresso without quickly diluting either. If the glass is taller (Collins style), a cylinder is the better fit. See the cube →
Espresso tonic.
A clear cylinder is the standard. Espresso tonic is built layered (tonic first, espresso poured over a spoon) and the layers stay visible longer with a single piece of clear ice in the glass. See the cylinder →
Iced Americano.
A 5 cm cube or a cylinder, depending on glassware. The cube is the safer default. The Americano build is forgiving but it does benefit from clean ice if you have it.
Cold drip and slow-extracted iced.
These coffees are made for clear ice. The brew itself takes hours to extract; the ice that finishes it deserves the same care.

FAQ
Does coffee really taste different with clear ice?
Yes, especially with single-origin or speciality coffee. Standard freezer ice carries dissolved minerals and freezer odours that mute the bean's flavour. Clear ice contributes much less, so the cup tastes closer to how the barista built it.
Which shape for cold brew?
A clear cylinder (4 cm by 11 cm) is the most common choice. It chills the vertical pour and melts slowly enough to last through the drink.
Which shape for espresso tonic?
A clear cylinder, or a 5 cm clear cube for a shorter glass. The layered build holds longer over a single piece of clear ice.
Which shape for iced latte?
A 5 cm clear cube works in a standard latte glass. If the glass is tall, a cylinder.
