It’s just another way to brew coffee. I found a Wikipedia page about and it appears to have been invented in 1830. Supposedly this method makes an exceptionally clear brew, low suspended solids. Looking at some pictures it doesn’t seem that complicated though there are some more artsy versions that make it complicated. If you do pour over coffee as your norm then this is probably a half step longer, but if you just have a machine then this is way more complicated.
