@Violet I’ve worked at a few different coffeehouses, and their equipment for making drip coffee isn’t any more advanced than what we have at home. Their equipment looks cool because it’s made of stainless steel, but coffeehouses brew drip coffee in the exact same way as you would at home. The biggest difference I can see is the freshness. One of the places I worked roasted the beans on-site, and many coffee places will grind the beans right before brewing them. There’s a huge volume of customers, so we went through a lot of coffee. If you have pound of coffee at home, it might last you several weeks (and it’s slowly losing flavor the whole time), but at a coffeehouse it doesn’t last the day.
If making drip coffee at home doesn’t taste that good, you could try getting a french press. It’s really simple to use one- just pour a bit of coffee in the bottom and add hot water, then let it steep for several minutes with the lid on. In the lid of the french press, there’s a filter that you slowly press down from the top, which pushes the grounds to the bottom. If you grind coffee at home, you’ll want to grind it finer than drip coffee but not as fine as you would for espresso. French press coffee turns out very strong and flavorful.
