To use the YunNasi Pour Over Coffee Maker, start by placing a paper or permanent filter in the coffee maker. Then, add your desired amount of coffee grounds to the filter. Next, heat water to the appropriate temperature and pour it over the coffee grounds in a slow, circular motion, allowing the coffee to drip through the filter into the jug below. Adjust the strength of the coffee by varying the coffee-to-water ratio and the speed of pouring. Once the brewing is complete, remove the filter and dispose of the grounds before enjoying your freshly brewed pour-over coffee.
