Know Your Roast

Understanding Roast Profiles

The same bean tells a completely different story depending on how it's roasted. Here's how to read the spectrum and find the roast that speaks to you.

Lightest Light Medium Dark Darkest
Light Roast
196–205°C
Roast Temperature
Light Roast
"The one that lets the bean speak"
Roasted just past the first crack. The lightest body with the highest acidity. This roast preserves the origin characteristics — you'll taste the terroir of the estate, the altitude, the soil. It's coffee at its most transparent and complex.
Flavor Notes
Citrus, Floral, Jasmine, Bright Fruit
Body
Acidity
High — bright and lively
Caffeine
Highest of all roasts
Best for: Pour Over, Cold Brew, AeroPress
Medium Roast
210–220°C
Roast Temperature
Medium Roast
"The heart of South Indian filter coffee"
The sweet spot. Roasted between first and second crack, this is the backbone of traditional South Indian filter coffee. Rich enough to stand up to milk, nuanced enough to appreciate black. The perfect all-day kapi.
Flavor Notes
Chocolate, Caramel, Toffee, Nutty
Body
Acidity
Balanced — sweet and smooth
Caffeine
Moderate
Best for: South Indian Filter, Drip, French Press
Dark Roast
225–235°C
Roast Temperature
Dark Roast
"Bold, intense, unapologetically strong"
Pushed past the second crack. The oils surface, the body becomes full and heavy, and the flavor is dominated by the roast itself — smoky, bold, and bitingly intense. This is the decoction your grandfather made at 5 AM.
Flavor Notes
Smoke, Dark Chocolate, Charred Wood, Pepper
Body
Acidity
Very low — thick and heavy
Caffeine
Lowest (burned off in roasting)
Best for: Espresso, Strong Filter Decoction, Moka Pot
Monsoon Malabar
Monsoon-Exposed
Natural Process
Monsoon Malabar
"A roast found nowhere else on Earth"
Not a conventional roast — it's a process. Green beans are exposed to monsoon winds and moisture on the Malabar coast for 12–16 weeks. The beans swell, lose acidity, and develop an unmistakable earthy, musty, spicy character unique to India. Then medium-roasted to preserve the monsoon magic.
Flavor Notes
Earthy, Spice, Tobacco, Musty Sweet
Body
Acidity
Almost none — smooth and mellow
Origin
Malabar Coast, Kerala
Best for: Filter Coffee, Espresso, French Press




Master the Method

Brew Techniques

The right technique can transform the same coffee into completely different experiences. Here are the four methods we swear by.

South Indian Filter
Traditional
The Original
South Indian Brass Filter
Patience is the secret ingredient. Gravity does the rest.
15 minBrew time
BoilingWater temp
Fine grindConsistency
How to Brew
1
Pack 3 tablespoons of fine-ground coffee into the upper chamber of the brass filter. Press gently with the plunger — firm but not too tight.
2
Pour boiling water to the brim. Close the lid and wait 10–15 minutes. Gravity pulls the decoction through into the lower chamber.
3
Mix 2 tablespoons of decoction with hot milk and jaggery (or sugar) to taste. Pour between davara and tumbler 3–4 times to froth and cool.
Best roast:
Medium Roast or Monsoon Malabar
Pour Over
Modern
The Slow Ritual
Pour Over
A slow, meditative pour that extracts bright, clean flavors.
4–5 minBrew time
92–96°CWater temp
Medium grindConsistency
How to Brew
1
Place a paper filter in the dripper and rinse with hot water. Add 15g of medium-ground coffee. Start your timer.
2
Pour 30ml of water in a slow spiral to bloom the grounds. Wait 30 seconds. The coffee will bubble and release CO2 — that's freshness.
3
Continue pouring in slow, concentric circles until you reach 250ml total. Let it drip through completely. Should finish around 4 minutes.
Best roast:
Light Roast Single Origin
Cold Brew
Patient
The Overnight Wait
Cold Brew
12 hours of patience. Zero bitterness. Maximum smoothness.
12–18 hrsBrew time
Room / FridgeTemperature
Coarse grindConsistency
How to Brew
1
Combine 100g of coarsely ground coffee with 600ml of cold or room temperature water in a jar. Stir gently to ensure all grounds are wet.
2
Cover and let it steep for 12–18 hours. Room temperature for bolder flavor, refrigerated for a cleaner, mellower taste.
3
Strain through a fine mesh or cheesecloth. Dilute the concentrate 1:1 with cold water or milk. Serve over ice. Keeps for 2 weeks refrigerated.
Best roast:
Light Roast or Medium Roast
Espresso
Intense
The Concentrated Shot
Espresso
High pressure, fine grind, 25 seconds of pure intensity.
25–30 secExtraction
90–96°CWater temp
Very fineConsistency
How to Brew
1
Dose 18g of very finely ground coffee into the portafilter. Distribute evenly and tamp with firm, level pressure (~15kg).
2
Lock the portafilter and start the shot. Water at 9 bars of pressure should produce a slow, honey-like stream — not gushing, not dripping.
3
Aim for 36ml of espresso in 25–30 seconds. The crema should be golden-brown and thick. Drink immediately or use as a base for milk drinks.
Best roast:
Dark Roast or Monsoon Malabar
