I benefited my trip to Magelang to visit coffee plantation here (previously known as Losari plantation). The guided tour by the resort staff was very informative. It cost some Rp 200k. Arabica, robusta, and excelsa types of coffee are grown on this site. It was unfortunately not the harvest season. I could only imagine the process between the harvest and roasting. I savoured Javanese robusta in kopi toebroek method, as well as whole-bean roasted coffee that I chewed with palm sugar lump. It tasted like coffee candy.
