Iced Pour-Over: Brew Hot Directly Over Ice

Flash-chilled coffee uses hot extraction and rapid cooling. Replace part of the recipe’s water with ice instead of simply pouring a full-strength hot brew over an unmeasured pile.

Good starting point

For a total 300 g water target, start with 20 g coffee, 180 g hot water and 120 g clean ice in the receiving server.

What to know before you begin

Ice mass counts toward the total brewing-water budget. This technique is distinct from brewing a full hot cup then cooling it later.

Step-by-step method

1. Place 120 g ice in a heat-safe serving vessel.
2. Prepare and rinse the dripper, discarding rinse water before positioning it above the iced vessel.
3. Add 20 g medium-fine grounds and bloom with a small portion of the 180 g hot-water budget.
4. Continue pouring the remaining hot water in controlled pulses to reach exactly 180 g of hot water.
5. Swirl to melt remaining ice, then serve; account for dilution from additional serving ice.

Problems to recognize

• Cup is too sharp: the reduced hot-water contact may require a slightly finer grind.
• Ice fails to melt: swirl gently and check total water weights.
• Glass cracks: use a vessel rated for temperature changes; avoid thermal shock.

Run a useful comparison

Compare 60% hot-water / 40% ice against 70% hot-water / 30% ice at the same overall recipe mass.
