How to Brew Light-Roast Coffee with a Pour-Over

Light roasts need hotter water, a slightly finer grind and a patient bloom. This recipe gives you a starting point and three adjustment paths for when the cup comes out sour, slow or harsh. For general technique and dripper choice, start with the complete pour-over guide.

Why pour-over is the best brew method for light-roast coffee

Light-roast coffee spends less time in the roaster, and Perfect Daily Grind notes that lighter roasts are less porous, so their compounds extract more slowly. The fix is to push extraction with hotter water, a finer grind and enough contact time. Pour-over brewing hands you direct control of all three, and the paper filter gives a clean cup that lets light-roast acidity and aroma read clearly.

Immersion brewers such as the French press also work for light roasts, but a pour-over lets you correct a sour or slow brew on the next cup by changing one variable at a time.

Light-roast pour-over recipe

The light-roast pour-over recipe below sits between two published V60 recipes: Kurasu brews 12 g of coffee with 200 g of water at 92-96°C, and Stumptown brews 21 g with 360 g of water just off the boil, about 205°F, in roughly three minutes. For light roasts, stay at the hot end of that range.

VariableLight-roast starting point
Coffee20 g
Water320 g (1:16)
Water temperature94-96°C (201-205°F), or just off the boil
GrindMedium-fine, one step finer than your medium-roast setting
Bloom50-60 g water, 45 seconds
Target finishAbout 3:00-3:30

The 94-96°C band sits inside the 92-96°C brewing range of the SCA Golden Cup standard. See the water temperature guide and coffee-to-water ratio guide for the wider context.

Equipment for the light-roast recipe

Step-by-step light-roast pour schedule

  1. Heat water to 94-96°C. Rinse the filter and discard the rinse water. Before brewing, give fresh beans time to degas; see how long to rest light-roast beans before pour-over.
  2. Add 20 g of medium-fine coffee and level the bed with a gentle shake.
  3. At 0:00, pour 50-60 g of water to wet all the grounds. Swirl once and wait until 0:45; light roasts benefit from the longer bloom.
  4. At 0:45, pour in slow spirals to 180 g.
  5. At about 1:30, pour to 320 g, keeping the stream in the center and off the filter walls.
  6. Give the dripper one gentle swirl to flatten the bed, then let it drain. Aim to finish around 3:00-3:30.

Fixing sour light-roast pour-over coffee

Sour, thin or salty light-roast pour-over coffee is under-extracted: water has not dissolved enough of the sweeter compounds. Make one change per brew, in this order:

  1. Raise the water temperature to 96°C or use water straight off the boil.
  2. Grind one step finer. Perfect Daily Grind's roast-level guide recommends a slightly finer grind for lighter roasts.
  3. Extend the bloom to 60 seconds and pour a little more slowly.
  4. Tighten the ratio to 1:15 (about 21 g for 320 g of water) if the cup is still thin.

The under-extraction flavor profile explains what each sour note points to. To tell a weak brew from an under-extracted one, see why a light-roast pour-over tastes thin: strength or extraction.

Fixing a long drawdown with light-roast pour-over

A light-roast pour-over that runs well past 4:00 usually means the grind has gone too fine, often after chasing sourness. Fine particles clog the paper filter, the bed stalls, and the cup turns bitter and dry while still tasting sour at the edges. To fix a slow light-roast drawdown:

Fixing bitter or harsh light-roast pour-over coffee

Bitter, drying or astringent light-roast pour-over coffee points to over-extraction or uneven extraction. Grind a step coarser, drop the temperature to 93°C, or lengthen the ratio to 1:17. If the cup is both sour and bitter, the extraction is uneven; fix the pour and drawdown first. The over-extraction flavor profile covers the tastes in more detail.

Light-roast pour-over FAQ

What is the best brew method for light roast coffee?

Pour-over is a strong brew method for light roast coffee because the brewer controls water temperature, grind size and contact time, the three variables that light roasts need pushed higher to extract fully. Paper-filtered pour-over also produces a clean cup that shows the fruit and floral notes light roasts are bought for.

What water temperature should I use for light roast pour-over?

Light roast pour-over works best at the top of the 92-96°C (197-205°F) range the SCA Golden Cup standard names. Water just off the boil, around 205°F, suits most light roasts.

Why does my light roast pour-over taste sour?

Sour light roast pour-over coffee is usually under-extracted. Grind finer, use hotter water, and extend the bloom before changing anything else.

Should I grind finer for light roast pour-over?

Yes. Light roasts extract more slowly than darker roasts, so a slightly finer grind than you use for a medium roast in the same dripper helps. Go finer in small steps and stop if the drawdown starts to stall.
