Freshly grounded roasted coffee grounds will always taste the best, but you can buy pre-ground beans if needed. You can buy grounds or roasted beans either online or at pretty much any grocery store or coffee specialty store.
The size of the grounds can make a considerable difference in your coffee quality. If your grounds are too large, water will drain through too fast and your coffee will have a weaker taste. If they’re too small, it’ll take forever to brew a cup. We’ll go into more detail in the following sections.
If you want to take your coffee brewing experience to the next level, you can buy your coffee beans green and roast them yourself. If you’re new to pour-over coffee, it’s going to be easier to buy roasted beans, to begin with, until you master this brewing technique. Eventually, you’ll want to try roasting your own because this will give you the ultimate coffee experience. Check out the video below for an in-depth explanation of why roasting your own coffee is superior to anything else and for roasting techniques.
