Indonesian Beans for Espresso Blend

Postby albertobali on Fri Jul 22, 2011 4:25 am

I need to make an espresso blend but I can use only Indonesian green beans.

Available to do the blend are:

Sumatra Aceh Gayo
Sumatra Mandheling
Sulawesi Toraya
Bali Kintamani
Bali Pupuan (robusta)

Which beans do you suggest to use and in which percentage?
and what is the expected tasting result of that blend?
Thanks

The Mandheling, Toraya, and Pupuan will give a heavy body and low acidity; these will be your base. The Pupuan will give a dense crema, the Mandheling woody flavors and the Toraya spicy ones. Try these on their own in various proportions until you get the richest mouthfeel and roundest, deepest flavors.

The Gayo and Kintamani are lighter and more acidic; they will add high tones and aroma to the blend. Try them brewed and see what proportion of each tastes best to you.

Then combine them. Typically espresso blends use 50% to 70% base coffees, and 30% to 50% flavor coffees

Thanks for your advice.

I would like to know what is the maximum proportion (%) of robusta (Pupuan) beans that the blend can contain?

Actually I have done a breakfast blend (black coffee) with this composition.
70% Pupuan (Robusta)
30% Bali Kintamani
and the pople like a lot.

for the espresso, I don't want to cross the line with too much robusta into the blend.
Thanks again

In Italy, espresso blends run from 0% to 100% Robusta; so there's no restriction there. You are looking for the best combination of mouthfeel and flavor.
