What things taste better with age? A look at foods, flavors, and how taste changes

According to research from the National Institutes of Health, taste perception can shift as we age, sometimes leading to a preference for more intense flavors. This shift helps explain why certain dishes and ingredients, like aged cheese and complex stews, are universally loved for how they develop and mature over time, leading us to ask: What things taste better with age?

Quick Summary

Many foods and drinks, including hard cheeses, dry-aged beef, and fermented items, develop more complex and mellow flavors as they age due to chemical changes, while dishes like soups and stews improve over time as ingredients meld together. Our own shifting taste buds as we age can also influence our appreciation for these rich and savory profiles.

Key Points

• Enhanced Umami Flavors: Many aged foods, like hard cheeses and dry-aged beef, develop a richer umami taste that can be more satisfying as our sense of sweet and salty changes with age.

• Mellowing of Acidity and Tannins: Processes like aging vinegar, fermenting foods, and cellaring wine help soften harsh, acidic, or tannic notes, resulting in a smoother, more balanced flavor profile.

• Flavor Integration in Leftovers: Dishes like stews, soups, and curries taste better the day after they're cooked because the ingredients have more time to infuse their flavors into the entire dish.

• Texture Development: Aging can drastically change the texture of foods, from the crystallizing of hard cheeses to the tenderizing of dry-aged beef, creating a more pleasant mouthfeel.

• Improved Palatability for Seniors: Incorporating aged and flavorful foods is a healthy aging strategy to combat declining taste sensitivity and improve appetite without resorting to excess sugar or salt.

• Concentration of Flavors: The loss of moisture during aging, as seen in dry-aged beef and balsamic vinegar, concentrates the existing flavors and makes them more intense.

The Culinary Alchemy of Aging

Food aging is a fascinating and complex process, transforming simple ingredients into complex masterpieces. From the cellar to the kitchen, time works its magic through chemical reactions that can mellow harsh flavors, deepen aromas, and tenderize textures. For older adults, understanding this process is not just a culinary curiosity but a way to embrace and adapt to changes in taste perception. When sweet and salty sensitivities decline, bold, savory umami flavors become a more prominent source of satisfaction, and aged foods are rich with this desirable quality.

Aged and Fermented Foods

Some of the most celebrated examples of food improving with age come from controlled aging and fermentation processes. The key to these changes lies in microbial action and moisture loss, which concentrate flavors and create new ones.

• Hard Cheeses: Hard cheeses like aged cheddar, Gouda, and Parmigiano-Reggiano become sharper and more complex over time. During aging, enzymes break down proteins and fats, creating a crystalline texture and developing rich, nutty, and savory umami notes.
• Balsamic Vinegar: Traditional balsamic vinegar is aged for a minimum of 12 years in wooden barrels, which progressively concentrates the flavor. The lengthy process results in a product that is sweeter, thicker, and far more complex than its younger counterparts.
• Fermented Vegetables: Items such as kimchi, sauerkraut, and pickles are left to ferment over time, allowing their intense acidity to mellow and complex flavors to balance out. This process not only improves taste but can also increase nutritional value by adding probiotics.
• Dry-Aged Beef: High-quality cuts of beef are dry-aged to allow natural enzymes to break down connective tissue, resulting in a more tender product. The process also evaporates moisture, concentrating the rich, beefy, and umami flavors.

The Importance of Umami

Umami, often called the fifth taste, is a savory flavor profile that becomes more noticeable and appreciated as we age and other tastes, particularly sweetness, may fade. Many aged foods, like cheese and dry-aged meats, are naturally high in glutamate, the amino acid responsible for the umami sensation. This makes them a great way to add flavor and depth to meals without relying on extra salt or sugar, which is a key consideration in healthy aging.

Foods That Get Better Overnight

Beyond long-term aging, some prepared foods simply taste better the next day after the ingredients have had time to fully meld. This is a simple but effective form of aging that anyone can practice.

• Soups and Stews: Letting a pot of soup, chili, or stew sit overnight allows the flavors to deepen and blend together more evenly. The various components, such as herbs, spices, and meats, have time to infuse the liquid, creating a more harmonious and rounded flavor.
• Curries: A day-old curry often has a more intense and integrated flavor profile, as the spices have had more time to meld with the sauce and other ingredients.
• Lasagna and Casseroles: Time allows the starches, cheeses, and sauces in baked pasta dishes to fully set and the flavors to concentrate, making the dish more cohesive and flavorful.

Texture	Firm and sometimes crystalline, due to moisture loss.	Soft and elastic.
Preparation Time	Requires years of controlled aging.	Can be produced quickly.
Taste Intensity	High, with concentrated flavors.	Low, with delicate flavors.
Primary Flavors	Umami, salty, sometimes pungent.	Milky, sweet, bland.

Beverages That Evolve with Time

It's not just solid food that benefits from time; many beverages also evolve and improve with a patient aging process.

• Wine: Certain wines, particularly high-tannin reds, are aged to allow the tannins to mellow and the flavors to become more complex and integrated. While not all wines are meant for long-term aging, those that are can develop incredible depth.
• Whiskey and Spirits: As whiskey and other dark spirits age in wooden casks, they extract flavor compounds from the wood, adding complexity, depth, and a smoother texture. The longer the maturation period, the more pronounced and complex the flavor profile becomes.

Adapting to Taste Changes in Senior Care

For those in senior care, embracing aged and flavorful foods can help improve appetite and nutritional intake. Since taste sensitivity often decreases, particularly for sweet and salty, incorporating naturally savory and robust flavors is a smart strategy. Encourage the use of umami-rich ingredients like mushrooms, aged broths, and high-quality balsamic vinegar to enhance dishes without excess sodium. Focusing on flavor-rich foods can make eating more enjoyable and nutritious.

Conclusion

The notion that things taste better with age is more than just a saying; it's a culinary truth backed by scientific processes. From the microbial magic of fermentation to the simple infusion of ingredients over time, aging transforms food into a richer, more profound experience. As part of a healthy aging strategy, embracing these complex and savory flavors can offer a more satisfying and nutritious approach to mealtime, adapting to the natural shifts in our taste perception while celebrating the deep, concentrated flavors that only time can produce.
