I like strong coffee with a bitter undertaste. Imho, everyone has slightly different taste buds. My sister always made coffee that was so weak that it tasted like coffee flavoured water to me, and she hated my coffee.
You can make Strong Coffee Weaker but you can never make Weak Coffee Stronger.
Which reminds me. I recall seeing a Get Smart Episode where Maxwell is sitting a Diner Counter talking to another Agent.
While he is talking, he isn't paying attention and is pouring heaping spoonfuls of Sugar into his Coffee Cup.
After he done talking, he takes a big Sip from the Cup, scrunches his face up and says, Yuck, I hate Luke Warm Coffee.
Wish I could find that scene. I think Mel Brooks wrote it.
