Isn't odd that your coffee tastes incredible one day and terrible the next? ☕ Chemistry explains it! The main flavor influencers include caffeine, chlorogenic acids (bitterness + antioxidants), lipids (oils that boost richness), acids (like citric and malic for brightness), and Maillard reaction products (toasty aromas). But the roast level is the biggest contributor. Light roasts preserve acidity and complex flavors, while dark roasts are bolder, bitter, and smoky.
Cool coffee chemistry!
