Is Reheating Coffee a Sin? A Barista's Guide to Coffee Etiquette
Taste Changes: Reheating coffee can alter its flavor. The initial taste, usually fresh and bold, often becomes bitter or flat when reheated due to oxidation.
Coffee Quality: High-quality beans tend to lose their flavor more quickly, so reheating can especially affect premium coffees.
Microwave or Stovetop?: The microwave is convenient but may not heat the coffee evenly. The stovetop can offer better control over temperature.
Best Practices: If you must reheat, do so gently. Avoid boiling the coffee, as extreme heat can further degrade the taste.
Brewing Techniques: Fresh coffee always tastes better than reheated. Consider making smaller batches if you don’t plan to finish it all at once.
Personal Preference: Ultimately, coffee is about what tastes best to you. Some people prefer their coffee a bit cooler or reheated, and that’s perfectly fine.
Barista’s Opinion: While many baristas may frown on reheating, it’s not exactly a "sin"—just a matter of personal taste.
Avoid Reheating Multiple Times: Reheating coffee multiple times can worsen the taste. It’s better to heat only once.
