Iced Pour-Over Calculator: Coffee, Hot Water & Ice

Calculate coffee grams, hot water and ice for iced V60 or pour-over. Count ice within the total water and save a recipe card.

Coffee
15 g
Hot water
168 g
Ice in server
72 g

Coffee: 15 g · 1:16. Total water + ice (g): 240 g. Hot water: 168 g. Ice in server: 72 g · 30%

Water and ice are input weights. Grounds retain liquid; extra serving ice changes dilution. These editable starting values are not a tested recipe.

How much coffee, hot water and ice do I need?

At 1:16 with 240 g total water and 30% ice, use 15 g coffee, 168 g hot water and 72 g ice. Ice is included in the 240 g, not added on top. Change all three inputs above to plan your own batch.

The formula is coffee = total water ÷ ratio; ice = total water × ice percentage; hot water = total water − ice. The calculator rounds coffee to 0.1 g and water to whole grams, keeping hot water + ice equal to the rounded total.

Brew over ice

Rinse the paper and discard the rinse water. Weigh ice into a suitable server, add coffee to the dripper, then brew with the calculated hot water over that ice. Follow your brewer and server instructions for hot liquids and cooling. Stir, check the remaining ice and taste. Additional ice in the glass adds dilution.

These are input weights, not an exact finished drink volume: grounds retain liquid, and ice may remain unmelted. Use the V60 guide for technique; its hot recipe's times are not a guarantee for this reduced-water brew. If you want a long cold extraction, use the cold brew calculator.

Source and starting values

Kurasu's iced recipe (opens in a new tab) uses 150 g hot water and 70 g ice. Our 1:16 and 30% defaults are an editorial adaptation, not that recipe or our physical testing. Adjust by taste and record what you actually brewed.
