We visited the coffee plantation, where we were taken around by a guide. He showed us the different types of trees used to grow coffee, cacao and lots of other spices/fruits. We were able to see coffee roasting and were given fruit teas and flavoured coffees to try for free.
They also sold luwak coffee for 50k, a special type of coffee made from the poo of a civet. They had a civet in a cage, ‘for display purposes only’, and wrote on a nearby board that these civets were released every week and a new one taken. Not sure how true this was.
At the end of the tour, we were taken to a shop where we could buy teas, coffees, oils and more. The guides do not pressure you to buy, but since the tour is free, you feel obliged to get something.
