You’re mom is right on the money. If it tastes right when she makes it, have her show you what her scoops look like. She probably is making her spoonfuls more or less heaping than you. For me, I like having stronger coffee, so my scoops are slightly heaped. Also, make sure that the amount of water you’re using is correct. On my coffeepot, I need to pour more water into the back of the coffee maker in order for it to brew 8 full cups. Hope that helps!
