When the weather cools in Milan, bushels of cavolo nero (dark green Tuscan kale) are my weekly order at the farmer’s market. My regular farmer winces when I tell him I’ll eat it raw — a homemade kale Caesar salad is a bittersweet taste of my former home, Los Angeles — but raw kale, like many bitter foods, elicits strong reactions.
Bitterness is a polarizing and fascinating flavor; one person craves raw kale or black coffee, and another finds it disgusting. During my gastronomy studies, I have learned the surprising importance of bitterness in Italy’s culinary story.
The five basic tastes include bitter, alongside sweet, salty, sour, and umami. How our brains interpret these tastes, and which foods contain them, is a story of both evolution and culture.
Plants developed bitter compounds as protection and a negative reaction to the taste was evolutionarily beneficial to avoid toxins, but those same chemicals are often nutritionally beneficial. Some people are genetically more sensitive to bitterness, but nurture also shapes perception. We can learn to enjoy the taste through regular exposure, especially as children. This is particularly evident in the different perceptions of bitterness between the U.S. and Italy.
Italy’s Bitter Balance
In the U.S., sweetness dominates; cereals, sodas, and even vegetables are engineered and prepared to taste mild. As a result, many Americans grow up exposed to bitterness only in negative contexts, such as medicine or spoiled food.
In Italian gastronomy, bitterness plays a key role in delicately balanced dishes. It can act as a contrast to rich meats, sweet tomatoes, and creamy cheeses.
Bitterness is further entrenched through ritualized aperitifs and digestifs to stimulate and aid digestion. Additionally, the ancestral wisdom required to forage and prepare tough, bitter greens and herbs into palatable dishes is a source of regional identity and cultural pride. Bitter is more than tolerated; it is part of a daily routine that connects consumption, wellbeing, and culture.
In Italy, bitterness is not an off-note to be masked but a beloved ingredient. From herbal liqueurs and leafy greens to intense espresso, bitterness is embraced in the Italian palate and lifestyle.
The Spirit of Amaro
The Italian adjective for bitter, amaro, refers to the herbal liqueur at the center of Italy’s love affair with bitterness. The dark, complex spirits are characterized by a bittersweet, herbaceous flavor, and are traditionally consumed after dinner to aid digestion.
My morning walk to class on the north side of Milan took me past a mysterious orange factory that wafts out perfume of peppermint, chamomile, and rhubarb. I discovered this is where Fernet Branca distills aromatic herbs into its signature amaro. The intense spirit, like many herb-based drinks, was initially developed and marketed as a medicine. Also headquartered in Milan is Campari, which produces a range of spirits including Cynar, an amaro made from artichokes and herbs. In Sicily, sweeter variations incorporate citrus peels. Across Italy, dozens of regional varieties showcase local ingredients in a delicate balance.
Amari (plural) are not only about taste, but are an after-dinner ritual to aid digestion and calm the stomach. Sipping an amaro signifies the slowing down at the end of a meal, a moment of reflection and community over shared bitterness.
Bitter Greens
Particular seasonal, and often foraged, bitter greens are prepared carefully to balance their bite. In northern Italy, radicchio is grilled, braised, or tossed into rich risotto. In Rome, puntarelle is balanced with salty anchovies and acidic vinegar. Across the south, wild bitter herbs are sautéed with garlic and olive oil.
While these dishes may not be friendly to the untrained palate, they offer rewarding complexity, depth, and nutrition. Bitterness is an Italian chef’s tool to cut through richness, contrast acidity, or stimulate the palate.
Espresso
Even Italy’s beloved coffee culture leans bitter. Italian coffee is heavily roasted, to the point of nearly burnt, and served short, black, and unsweetened. Perhaps a dollop of foam or a splash of milk provides balance.
The Italian morning begins with a small coffee while standing at the bar, and meals are followed by an espresso as a digestive aid, like amaro. These thimble-sized moments in Italian eating patterns are purposeful, restrained, and entwined with wellness.
The Bitter Revolution
While bitterness has long been sidelined in American cuisine, the tide may be turning. Ingredients once rejected for being too intense are now marketed for their ability to “cleanse,” “detox,” or “stimulate digestion.”
The shift toward a functional view of food indicates recognition of what Italians have long understood. Bitterness is not a flaw to fix; it is a deliberate element for balance, contrast, and healthy digestion. Whether in a bite of radicchio, a bracing sip of amaro, or a shot of unsweetened espresso, flavor should engage and stimulate you.
Perhaps the lost flavor of bitterness will soon be reclaimed and appreciated abroad as it is in Italy. The next time a Negroni seems too sharp, or a leafy green salad too assertive, we can take a cue from Italians: lean into it, because bitter is better.
