South Indian Filter Coffee

The classic davara tumbler — South India's most beloved morning ritual.
The South Indian metal filter works by slow drip — water passes through the grounds over 10–15 minutes, producing a thick, concentrated decoction. You need a medium-fine grind, slightly coarser than espresso, to allow water to pass through at the right pace without clogging.
Robusta is the traditional choice here and for very good reason. Its higher caffeine content, dense body and low acidity produce the thick, dark decoction that makes authentic kaapi what it is. If you want some smoothness alongside the strength, the 70-30 blend softens the edges while keeping the body bold.
Recommended: 100% Robusta Medium Dark Roast — built for the South Indian filter, thick decoction, strong and bold.
Shop Robusta →Espresso

A properly pulled espresso shot — golden crema on top, rich and dense.
Espresso demands a fine, consistent grind — think table salt texture. The high-pressure extraction happens in under 30 seconds, so you need maximum surface area for the water to pull flavour efficiently.
Robusta shines in espresso. Its higher oil content produces a thick, persistent crema — that golden layer on top that espresso lovers obsess over. The 70-30 Blend gives you Arabica complexity with Robusta crema — excellent for lattes and cappuccinos where the espresso needs to hold its own against milk.
Recommended: 70-30 Arabica-Robusta Blend — thick crema, bold body, smooth enough for milk-based drinks.
Shop 70-30 Blend →Pour Over (V60, Chemex, Drip)

Pour over — slow, controlled, and the best way to taste Arabica's full character.
Pour over is where Arabica truly shines. The slow, controlled pour extracts the delicate floral, fruity and caramel notes that Arabica is known for — notes that get overwhelmed in faster, higher-pressure methods. Use a medium-fine grind, roughly coarse sand texture.
Our 100% Arabica Medium Dark Roast is ideal here. The medium dark roast brings out caramel sweetness and a smooth body without the harsh bitterness of a full dark roast — perfect for a slow morning pour.
Recommended: 100% Arabica Medium Dark Roast — smooth, floral, low acidity. Made for slow brewing methods.
Shop Arabica →French Press

French press — full immersion, full body, full flavour.
French press is full immersion brewing — the grounds sit in hot water for 4 minutes before you press the plunger. This demands a coarse grind, like rough sea salt. Fine grounds over-extract in 4 minutes and also push through the metal filter into your cup.
Arabica works beautifully here. The longer steep draws out its natural sweetness and complexity. Our 80-20 Blend is also excellent — the Robusta adds just enough body and depth to make the cup feel substantial without overwhelming the Arabica's character.
Recommended: 80-20 Arabica-Robusta Blend — smooth and velvety with just enough Robusta depth for a satisfying press.
Shop 80-20 Blend →Moka Pot
The moka pot — stovetop espresso, Italian-style, Indian soul.
The moka pot forces pressurised steam through the grounds — not quite espresso pressure, but close. Use a medium-fine grind. Too coarse and the coffee will be weak and watery. Too fine and you risk clogging the filter basket.
Robusta handles the moka pot's intense heat and pressure brilliantly — strong, rich, with good body. The 70-30 Blend softens it slightly while keeping the intensity.
Recommended: 70-30 Arabica-Robusta Blend — intense enough for the moka pot, smooth enough to drink straight.
Shop 70-30 Blend →Cold Brew
Cold brew — smooth, low-acid, naturally sweet. Perfect for Chennai summers.
Cold brew is steeped in cold water for 12–24 hours — the extra long contact time means you need an extra coarse grind, even coarser than French press, to avoid over-extraction and bitterness.
Arabica produces a naturally smooth, slightly sweet cold brew with incredibly low acidity. Starting with a naturally low-acid bean like our Arabica Medium Dark Roast gives you an exceptionally smooth result — ideal for Chennai's heat.
Recommended: 100% Arabica Medium Dark Roast — low acidity, natural sweetness, perfect for cold brew concentrate.
