Why Does Coffee Taste Both Sour and Bitter? Which Coffee Beans Are Neither Sour Nor Bitter - Price of Non-Sour, Non-Bitter Coffee Beans

Is Coffee Sour?

Coffee beans come from coffee fruit, so they contain acidic substances.

There are two kinds of coffee sourness: one is the bright, lively "fragrant acidity," and the other is the sour-but-unfragrant "dead acidity."

Fragrant acidity tastes like the fresh scents of lemon, apple, and citrus — refreshing and pleasant, like juice. Dead acidity is as hard to swallow as white vinegar, and thoroughly unappealing.

All green coffee beans contain both fragrant and dead acidic components. Maximizing the fragrant and minimizing the dead comes down to the roaster's skill; on the other hand, the darker the roast, the higher the degree of caramelization, the more acidic substances are destroyed, and the less likely sourness is to appear.

Is Specialty Coffee Bitter?

Many friends say coffee is very bitter and hard to drink. In fact, that is because most coffee shops "use bitterness to cover flaws," roasting deeply to mask undesirable off-flavors.

The bitterness of coffee depends mainly on:

The nature of the green beans — the flavors produced by their growing regions and methods.

The quality of the green beans — whether there are defective or flawed beans.

Roasting — the depth of the roast and the roasting technique.

Poor-quality beans will show undesirable flavors, even off-flavors. The so-called "using bitterness to cover flaws" is really an attempt to hide poor flavors behind the bittersweet taste of a dark roast, but it often backfires: poor roasting produces a burnt, bitter, unpleasant cup.

Specialty Coffee, As It Should Be.

High-quality beans, combined with good roasting technique, can bring out refreshing, pleasant sweet-and-sour flavors in a light roast; a medium roast offers moderate body with balanced sweet, sour, and bitter notes; while a dark roast has weaker acidity with rich, mellow, aromatic flavors.

Some people like the sensation of sweet and sour stimulating the tongue, some prefer balanced sweet-and-sour flavors, and others enjoy a mellow, refreshing taste.

There is no best flavor, only the flavor you like most.

From today onward, choose the coffee flavor you like.

FrontStreet Coffee Recommendation

In roasting, three factors decide the final flavor and must be balanced: acidity, sweetness, and bitterness. The darker the roast, the bitterer and heavier the coffee; the lighter the roast, the more acidic and lighter-bodied it becomes. So for anyone after a balanced cup, medium-roasted beans are the best place to start.

If you dislike both sourness and bitterness, reach for FrontStreet's Queen Estate coffee. Grown in Brazil, the world's largest coffee producer, it is a distinctive Yellow Bourbon with a fresh, sweet taste that medium roasting turns into creamy peanut, chocolate, toasted bread, and sugarcane aromas and sweetness. It works for pour-over as well as moka pot and espresso machine. For a sweeter medium roast, FrontStreet's Strawberry Candy leads the way, thanks to its fruit character. Unlike other fruit-forward coffees, it blends two well-known Central and South American origins — a honey-processed Costa Rican coffee and a washed Panama Geisha. To highlight the best of both, FrontStreet roasts it medium, so it delivers both orange-blossom-and-honey notes and a rounded sweetness, suited to cold brew, pour-over, and espresso alike and refreshing on entry.

As a representative Chinese specialty coffee, FrontStreet's 2013 sun-dried Typica carries the classic Yunnan small-bean character. To restore its balanced, gentle profile, it is roasted medium, showing soft notes of nuts, brown sugar, black tea, and dried apricot, usable for pour-over, cold brew, and drip machines, with excellent value. Finally, FrontStreet's Jamaica Blue Mountain No. 1 is grown from the Typica variety, a world-renowned fine Arabica, and Jamaica's exceptional geography is essential to Blue Mountain's balanced flavor. Known as the "emperor of coffee," it is roasted medium so its distinctive acidity, bitterness, sweetness, and body fuse perfectly into a strong, alluring elegance on the nose, with chocolate, roasted nuts, cream, and caramel flavors on entry — something no other coffee quite matches.
