the only thing that you have to do is drink your coffee with a lot of joy and happiness.
I agree with that!
I started out drinking coffee with milk, sugar, and a sprinkling of cinnamon. That was always a real treat. then I would skip cinnamon... then many years later I stopped sugar overnight, and for about 4 or 5 years now, I have coffee black unsweetened.
I think it took me a while to have a full appreciation for the taste. Every now and then I'll have a cappuccino or a latte, but I tend to do that when I go out to a coffee shop, or if I'm with someone who has a Nespresso Machine:)
I guess everybody does have some taste shifting for coffee as time passes. I started my coffee journey with instant coffee plus sugar and creamer. Then came the espresso machine, with some sugar added. Now I’m also straight black, maybe at least for 6-7 years. This seems the longest period. No intentions of stepping back! But when the taste of coffee is beautiful and complex, then why would you need sugar at all? But this is just my way of coffee happiness!
I understand the changing of taste you mention. As we mature, our taste matures with us I think. As a kid I loved all my drinks sweet, be it tea of coffee or juices etc! But I too have given up sugar with time and have learned to enjoy regular plain black coffee!
