While many commercial coffee makers can handle multiple pots at once, if you’re one person looking to serve yourself and/or a few others, a size of around five cups of coffee should be good enough. The Simply Brew Coffee Maker claims to serve five cups in one go, which is a great size. Suppose you’re looking to accommodate more for yourself or others. In that case, you can go with a bigger option, like the 56oz Personal Cafe Coffee Maker or the even bigger Savoy Programmable Coffee Maker. Unless you’re making coffee commercially or for a huge party, you shouldn’t need any more than 14 cups at once, as you can brew multiple times.
