BREW TEMPERATURE GUIDE
What Temperature Should You Use for Brewing Light Roast Coffee?
94 to 96°C works for most light roast filter coffee. Some naturals do better a touch cooler.
A good starting point for brewing light roast coffee is the 94 to 96°C temperature range. Light roast coffee is more dense than a medium or dark roast. It needs the heat to give up sweetness and body along with the pronounced acidity.
If you drop too far below that, the cup often turns thin and sour unless you make up for it elsewhere with a finer grind, more contact time, or more agitation. Increasing the temperature by a couple of degrees can mitigate this.
The right temperature also depends on the brewer and the coffee you have in front of you. A washed coffee brewed with V60 does better on the hotter end. Naturals and anaerobics do better with a little less heat.
Right temperature
The right temperature for light roasts
For most pour over and filter brewing, 94 to 96°C is the right place to start. Then taste the cup and move a little, not a lot.
Light coffee is denser than a medium or dark roast. This means the water has to work harder to get the soluble material out of it. That is why 95°C can taste sweet and balanced while 90°C with the same coffee can taste thin or sour. That does not mean hotter water fixes everything. While Temperature speeds up extraction, it does not rescue a bad grind, a weak recipe, or a brewer that doesn’t hold the temperature well. I still adjust the grind first most of the time and use temperature to finish the dial in.
Light roasts want more heat, especially in brewers that already lean toward clarity.

Use this as a starting point and find the setup closest to what is on your counter
V60, washed light roast
Washed Ethiopians and Kenyans in a V60 do well with a little more heat. The brewer already leans lighter in body, so the extra degrees help fill in the cup profile. If the cup is grassy or thin, grind finer, and if that doesn’t help, start dropping the temperature.
V60, natural or anaerobic light roast
I start naturals and anaerobics a couple of degrees lower in a V60. You still get the fruit, but you are less likely to end up with that boozy finish that shows up when these coffees get overextracted.
Flat bottom brewer, washed light roast
Flat bottom brewers already give you a fuller cup than a V60, so washed light roasts often do well with a touch of lower temperature. If the cup feels hollow though, you can try increasing the temperature of the water by a degree or two.
Flat bottom brewer, natural or anaerobic light roast
A flat bed brewer already produces a heavier cup profile. With a large natural process coffee, that can make the cup feel overly dense or rough. A slightly lower brewing temperature usually preserves the fruit character while keeping the finish cleaner.
AeroPress, official style
85°C is the official AeroPress starting point for medium and light roasts. It can work, but with lighter specialty coffee I often find it too muted unless the grind is very fine and the recipe is built around it.
AeroPress, specialty roaster style
I find light roasts tend to do better with higher temperatures in the AeroPress. If the cup tastes thin or sour, leave the temperature where it is and grind finer first. If the cup starts tasting bitter or astringent, a lower temperature might fix that.
Temperature is one variable. Grind size, contact time, agitation, and water are all influencing how a cup tastes.
Recipes
Three starting recipes that work well with light roasts
Washed light roast, dripper
Medium fine grind. Bloom with 45g for about 35 seconds, then finish in two pours. Total brew time around 2:45 to 3:15. This is where I start with washed Ethiopians, Kenyans, and light Colombians.
AeroPress, hot lane
Fine grind. Quick stir, steep for about 1:30, press gently. This is the recipe I go for when my light roast AeroPress cups taste flat.
Natural light roast, dripper
Medium grind, just a touch coarser than the washed recipe. Aim for around 3:00 total brew time. Works well on natural Ethiopians and fruit heavy anaerobics.
Bean discovery engine
Sometimes the brew is fine. The coffee just is not your kind of coffee.
Use the bean discovery engine to filter by flavor family, roast style, and process, then pick a coffee that lines up with the way you actually like your cup to taste.
Naturals
Natural light roast brewing temperature
I have brewed the same origin as both a washed and a natural side by side with the same dose, grind, and water. The natural usually hits that jammy, fermenty edge faster. Same roast level on paper, different behaviour in the brewer. 92 to 94°C is a good starting place for most natural and anaerobic light roasts. You still have enough heat to keep the fruit from tasting raw or green, but there is more room before the finish goes boozy or overripe. If the cup is sour and underripe, go hotter. If it turns into berry syrup with a rough finish, back off a couple of degrees.
Heat loss
Kettle temperature and slurry temperature are different
A temperature controlled kettle helps improve your brewing because it lets you test small temperature changes more reliably. However, the dripper is cooler, the filter is cooler, the grounds are room temperature, and you lose heat the second water hits the bed. You might see two people say completely different things about temperature and both still get good cups. One person brews at 96°C, another pours straight off boil, and they land in roughly the same place once the slurry settles down. If your light roast keeps coming out thin and watery, preheat the dripper and rinse the filter with hot water before you start. Keep the pours moving so the bed does not cool down between pours. Sometimes the fix is simply better heat retention rather than changing the kettle setting.
