Coffee is more than a morning ritual—it’s a story of culture, commerce, and chemistry. In this episode, we trace coffee’s origins on the Ethiopian plateau, its rise as a global commodity, and its role in shaping social life through the rise of coffeehouses. We also dive deep into the science: how caffeine sharpens alertness by blocking adenosine receptors, and how genetics, age, and circadian rhythms shape your personal coffee experience. A blend of history and biology in every cup.#CoffeeHistory #CoffeeScience #CaffeineFacts #MorningRitual #Adenosine #Chronobiology #GeneticsAndCaffeine #Podcast
