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.
The Right Temperature for Light Roasts
As we get asked for the ideal brew temperature for light roasts all the time, we thought it would be a good idea to put together a guide, starting at 94 to 96°C (201°F to 205°F) for pour over and filter brewing. Light coffee is dense. It needs that heat to give up the good stuff, the sweetness and the body that make the cup feel complete. Drop too far below that and you’ll usually end up with something thin and sour, unless you’re compensating elsewhere in the recipe (finer grind, longer contact time, more agitation).
Quick Temperature Brewing Guide for Light Roasts
We put together starting points for six situations that come up the most. Find the one closest to what you’re brewing right now and go from there.
Start at 95 to 96°C / 203 to 205°FHigh clarityFast drawdownCenter the sweetness
V60, washed light roast
Washed Ethiopians and Kenyans in a V60 almost always want the hotter end. The V60 already leans toward clarity and a lighter body on its own, so you need the extra heat to fill in the middle. If the cup is still sharp or grassy or thin, grind finer before you start dropping temperature. I see people reach for the temperature dial first when the grind is usually the issue.
Start at 93 to 94°C / 199 to 201°FKeep the fruitWatch the ferment edgeClarity first
V60, natural or anaerobic light roast
I almost always start naturals and anaerobics a couple degrees cooler in the V60. You still get the fruit, but you’re way less likely to end up with that boozy, fermenty finish that can happen when you push these coffees too hard. If the fruit seems buried or the cup just tastes sour and thin, go hotter.
Start at 94 to 95°C / 201 to 203°FMore bodyRounder cupSweetness first
Flat bottom brewer, washed light roast
Flat bottom brewers (Kalita, April, etc.) already give a rounder, fuller cup than a V60, so washed light roasts often do well a touch lower. Good spot when you want sweetness and a bit more body without the finish dragging. Go hotter if the cup feels hollow and all you taste is acidity. Back off if it starts tasting heavy or overbuilt.
Start at 92 to 93°C / 198 to 199°FManage jamminessMore weightShorter leash
Flat bottom brewer, natural or anaerobic light roast
Probably the easiest combo to overshoot. The flat bed brewer already adds weight, so a big natural on top of that can turn syrupy or rough fast. Starting cooler keeps the fruit ripe without letting things get overripe. Only go hotter if the coffee is sour and the fruit never opens up. Go cooler if the cup gets sticky or drying through the finish.
Start at 85°C / 185°FCompact cupFine grindShort contact
AeroPress, official style
This is AeroPress’s own starting point for medium and light roasts. It can give you a smooth, compact cup with a fine grind and short contact time. Move hotter when the cup tastes flat, sleepy, or low aroma. Jump from 85°C / 185°F to about 94°C / 201°F first, go lower temperature only after checking grind and agitation first, because harshness here often comes from other parameters rather than temperature alone.
Start at 94 to 96°C / 201 to 205°FMore aromaMore acidityMore shape
AeroPress, specialty roaster style
Where a lot of specialty roasters land for their light roasts, and honestly where I start with the AeroPress most of the time. The official 85°C recipe just keeps coming out muted on anything lighter than a medium. Go hotter if the cup still feels empty in the middle. Back off if it gets dry or muddy.
Taste the Cup, Then Adjust
Light roasts want more extraction energy than darker coffee, that part is pretty straightforward. But I’ve seen people crank their EKG to 100°C and wonder why the cup tastes harsh and dry. Temperature is one variable. Grind size, contact time, agitation, your water… all of that is doing work too. Change one thing at a time and taste after each adjustment.

Three Starting Recipes That Work Well With Light Roasts
Washed light roast, dripper
15g in, 250g water, medium fine grind, 95°C. Bloom 45g for about 35 seconds, finish in two pours, TBT around 2:45 to 3:15. I use this as my starting point for washed Ethiopians, Kenyans, and light Colombians.
AeroPress, hot lane
18g in, 210g water, fine grind, 95°C. Quick stir, steep for about 1:30, press gently. This is the recipe I hand people when their light roast AeroPress cups keep coming out flat.
Natural light roast, dripper
15g in, 250g water, medium grind (slightly coarser than the washed recipe), 93°C. Pour a bit calmer, aim for about 3:00 TBT. Works well on natural Ethiopians and those fruit heavy anaerobics without pushing them over the edge.
Why Light Roast Usually Likes More Heat
When coffee gets roasted light, it keeps more of its original cell structure. The bean is denser and less porous than a medium or dark roast, and water has to work harder to get the solubles out. Hotter water makes that easier. That’s why the same coffee can taste bright and sweet at 95°C and then just kind of… sour and thin at 90°C. A few degrees makes a real difference with light roasts.
That said, hotter water doesn’t add flavor on its own. It just speeds up extraction. The cup you end up with still depends on how much you extracted overall, how strong the brew is, and whether the water moved through the bed evenly. Push any recipe too far and you’ll still get something dry or woody or bitter. Temperature is one knob on the brewer. I’ve had way more luck adjusting grind size first and using temperature as a finishing touch.
Natural Light Roast Brewing Temperature
Naturals don’t need a completely different approach, but they tend to like a small step down in temperature. I’ve brewed the same origin as both a washed and a natural side by side (same dose, same grind, same water) and the natural hits that jammy, fermenty edge way faster. It’s the same roast level on paper but the bean behaves differently in the brewer.
92 to 94°C is a good starting place for most natural and anaerobic light roasts. You still get enough heat to keep the fruit from tasting raw or green, but there’s more room before the finish goes boozy or overripe. If the cup tastes sour and underripe, go hotter. If it tastes like berry syrup with a rough, drying finish, back off a couple degrees.
Kettle Temperature and Slurry Temperature Are Different
Your kettle might say 96°C but the actual coffee bed is cooler than that. The dripper is cool, the filter is cool, the grounds are at room temperature, and you lose heat the second water hits the bed. I think this is why you see people on reddit saying completely different things about temperature and both getting good cups. One person brews at 96°C on the EKG, another pours straight off boil, and they end up in roughly the same place in the slurry.
If you’re brewing light and the cup keeps coming out thin and watery, try preheating your dripper and rinsing the filter with hot water before you start. Keep your pours moving too so the bed doesn’t cool down between pours. I’ve fixed more “temperature problems” with better heat retention than with actually changing the kettle setting.
