Or maybe you dig into a cappuccino that’s gone cold, the milk foam turning funky and flat. Sound familiar? That moment when a perfectly good cup of coffee gets ruined by the wrong temperature? Most people don’t realize this: even if you’ve got top-quality beans, expert roasting, and precise extraction—if the temperature isn’t right, all that effort goes to waste.

When we taste coffee, aroma and flavor are inseparable — aroma comes from volatile compounds, and temperature directly determines how much of that aroma reaches our senses. At higher temperatures — especially around 61–62°C (about 142°F) , widely considered the optimal drinking temperature — the fruity, caramel, and floral notes in the beans are released most vividly. Take the “Mozart” beans from Costa Rica’s Musician Series, for example: right after brewing, the jasmine fragrance hits you first, fo...
