If you're looking for the best coffee grind for your automatic pour-over coffee maker, keep a few things in mind. First, the grind should be uniform and consistent. Otherwise, you'll end up with an uneven brew that can be bitter or weak. Second, a medium grind size usually works better for pour-over coffee makers. This will help ensure that all the coffee grounds are extracted during the brewing process. If you get a muddy coffee bed or an overly bitter result, try to grind coarser. On the contrary, if you get large boulders on the brew basket, with a weak cup of coffee, and a sour taste, try to get finer grounds. Finally, make sure to use freshly ground coffee for the best flavor. Pre-ground coffee can quickly lose its flavor and aroma, so it's best to grind your beans right before brewing. You can find the perfect grind for your automatic pour-over coffee maker by keeping these factors in mind.
