  1. Where it grows

    Kaapikaadu Estate, in Karnataka. The estate puts its robusta through named ferments, the kind most growers keep for arabica. A champagne yeast goes on one lot and a Kölsch beer ferment on this one. The lot is canephora, and it was chosen for flavour rather than for caffeine.

  2. The ferment

    Before its natural dry, this lot was fermented with Kölsch beer. What the ferment leaves is a deeper, malt-like sweetness and a rounder structure, closer to a malted biscuit than to fruit, with golden raisin and dark honey behind it.

  3. How we roast it

    Depth 32, medium light. At this roast bitterness stays unusually low while the heavy canephora mouthfeel is left intact, and the finish is long. As espresso the cup moves to toffee and stout cacao over brown sugar. Roasted to order in New Delhi.

  4. What to expect

    It is a heavy, sweet coffee with a long finish, so it is a cup to drink slowly rather than a quick, bright filter. If you want the bright, sparkling one from the same estate, that is Étoile Noir. The recipes here are starting points for espresso, moka pot and pour-over.

05questions
Does Maltline taste like beer?

No. The Kölsch is used in the ferment, before the lot is dried. What it leaves is a malt-like sweetness: malted biscuit, golden raisin and dark honey on filter, toffee and stout cacao as espresso.

Is there alcohol in it?

The Kölsch is used in the ferment, before the coffee is dried and roasted. If alcohol matters to you for any reason, message us on WhatsApp before you order and we will tell you what we know.

Is Maltline bitter?

It is roasted medium light to keep bitterness unusually low, while the heavy robusta mouthfeel stays. The finish is long.

Which brewer suits it, and can I get it ground?

It is listed for espresso, moka pot, AeroPress, French press and pour-over. Pick the size, 250 g or 1 kg, and the grind when you add it to the cart: whole bean, home or commercial espresso, South Indian filter, AeroPress, moka pot, pour-over, Chemex, French press or cold brew. Whole bean keeps longest.

What if it is sold out?

Use Notify Me on the page and tell us. If it comes back, we will let you know the day it does. Coffee is bought in lots, so a sold-out bag may not return.
