Yeah pretty similar here in Indonesia. The bulk of the coffee (kopi) you find for sale outside big supermarkets is robusta. Normally its roasted with some corn thrown in and (as Maxtor mentioned) often the finishing touches are a lump of butter and some salt added. This is the most traditional way of roasting and unlike Malaysia most of the roasting is done in small drum roasters...often turned by hand for up to 3 hours! The coffee produced is an acquired...or sometimes impossible to acquired taste! Generally the kopi is prepared by grinding it very fine. Most markets use mechanised stone bur grinders. The powder these things can produce is incredible...makes my Mazzer look like its throwing out chunks! Of course a percentage of the powder is ground stone, as the stones in these grinders last only 2-3 weeks. I have got some pictures of a local roaster and one of these grinders, powered by a Yannma boat engine, in action if anyone is interested in seeing.
Anyway once the coffee is ground it is called Kopi bubuk (literally powdered coffee). To prepare a drink several spoons are heaped into a glass with several spoons of sugar and boiling water is added. Indonesians can not generally stomach coffee without sugar. It is always drunk black, probably due to the cost and general unavailability of milk.
Malayasia is certainly a market that is ahead of Indonesia, but behind Singapore, in terms of development of the specialty coffee industry. There are some good local roasters in KL, as well as JB, Melaka and Penang. There are also literally hundreds of small roasters that follow the methods descriped by Maxtor. In Penang there is a small coffee shop on nearly every corner...mostly run by the Chinese these places are often open fronted with a jumble of tables and chairs occupied by older Chinese, Malays and Indians passing the time away. I had a chance a few years ago to spend a couple of days in one of these places in Penang...it was fascinating. The greens in those days, and I am sure know too, were robustas from Lampung and Takengon in Sumatra. The place I spent in cooked all their beans, rather than using a roaster. They used huge woks over LPG burners. It was damn hot, with very little ventilation out the back where they cooked up. In this particular place they added butter but also some herbs to the coffee. This place, although small, went through quite a volume of green beans.
