I haven’t got the hang of how to use the coffee-making machine yet.

不知道怎么用这个咖啡壶呢。

The counterman scooped out Sumatran coffeebeans,ground them,put the grounds in a filter in the cone and poured hot water over them to give me a sample of their product.

柜台服务员用勺子舀出少许苏门答腊咖啡豆，磨成粉，倒入滴式咖啡壶的格，浇下热水，冲一杯咖啡供品尝。
