How Much Water for 15g Pour-Over Coffee? The Correct Technique Explained

FrontStreet Coffee - Panama Hartman Pour-Over Sharing

Practical Water-to-Coffee Ratios for Pour-Over

[Bold flavor] 1:10~1:11 (grams of coffee to milliliters of brewed coffee), which equals 1:12.5~1:13.5 under the Golden Cup Standard (bean weight to total water poured)

[Medium flavor] 1:12~1:13 (equivalent to 1:14.5~1:15.5 under the Golden Cup Standard)

[Light & fresh] 1:14~1:16 (equivalent to 1:16.5~1:18.5 under the Golden Cup Standard)

Even with the right measurements, a poorly chosen brewing ratio won't produce delicious coffee. During the learning process, repeated tasting and concentration testing are needed to discover the optimal pour-over ratio - grams of coffee to milliliters of brewed coffee between 1:12~1:13. This corresponds to the four major Golden Cup systems in Europe and America, with coffee-to-total-water at 1:14.5~1:15.5, making it easiest to land inside the "Golden Cup square" of an 18%~22% extraction yield and 1.15%~1.35% concentration - avoiding both a thick, muddled cup and a watery, diluted one.

FrontStreet Coffee believes most pour-over enthusiasts' ratios should fall within this range. Our most commonly used pour-over ratio is 1:15~1:16, equivalent to 1:16.5~1:18.5 under the Golden Cup Standard.

Of course, some brewers adopt more extreme ratios. Those who prefer bold flavors often brew at 1:10 (equivalent to 1:12.5 on the Golden Cup scale), using higher concentration to compensate for insufficient extraction - deliberately extracting only the lower- and medium-molecular-weight sweet and sour compounds while avoiding the heavier bitter ones. Although this can produce a rich and delicious cup, the concentration is too high for most palates and it wastes a lot of coffee, so it isn't something we encourage. In fact, a more conventional 1:12 (equivalent to 1:14.5 on the Golden Cup scale) will also produce a very rich, satisfying cup.

Brewing Analysis

Recommended brewing methods: siphon, pour-over

Grind size: 3.5 (Fuji Royal R440)

Water temperature: 90°C

V60 dripper, 15g of coffee, water temperature 90°C, grind size 4, water-to-coffee ratio close to 1:15

Bloom: 30ml of water, bloom time 30s

Staged pour: pour to 110ml, pause, then slowly pour to 225ml

Flavor profile: smooth entry, lively and bright acidity, soft yet layered, a red wine aftertaste, with distinct honey and sugarcane flavors. Once fully cooled, brown sugar notes emerge.

FrontStreet Coffee Recommendation

Panama is home to some of the world's most celebrated specialty coffee, and FrontStreet Coffee's Boquete Washed Geisha is the perfect estate-level introduction to the origin. Grown at 1,600m on the volcanic soils of the Barú volcano region, it brews into jasmine florals with green tea, honey, citrus, and orange - precisely the kind of delicate aromatics that reward a controlled 1:15 pour-over. If you fall for it, the FrontStreet Esmeralda Red Label Geisha is the ultimate upgrade: harvested from single plots above 1,700m and cupping at 91 points, it represents the very top of the Geisha hierarchy.
