As adults, we can drink whatever we want, whenever we want. But there is a certain stigma that comes with throwing back, say, a couple of glasses of wine during lunch or an espresso late into the evening. "Do you want to be up all night?" is a common nag.
But elsewhere in the world drinking coffee before bed doesn't seem to be a concern. In countries like Italy, Spain, and France, for example, late-night coffee culture is everywhere. Can certain cultures handle caffeine — the most consumed psychoactive drug in the world — late at night better than others? Can we all drink a lightly roasted cup of coffee after dinner and sleep through the night?
Here, we seek to better understand the after hours coffee-drinking culture to figure out why some people can throw back espressos before going to sleep.
Espresso after dinner
Many folks think espresso is a super strong category of its own — a different bean, if you will — but that’s not true. “An espresso roast is really just marketing,” says illy’s master barista, Giorgio Milos. In fact, Milos says that most all coffee beans can be transformed into espresso if ground to the proper specification.
“Some roasts, blends, and single origins taste better for non-espresso preparations and some taste better for espresso preparation,” he adds. “Ultimately, taste is subjective, and it comes down to personal preference. For me, balance and complexity of aroma are the key to a great espresso, which can be achieved from a medium-roast blend.”
Is espresso more caffeinated than coffee?
A cup of espresso is small but packs a big punch. “Even though espresso carries less caffeine than filter or other coffee methods, the concentration is much higher, so your body absorbs less caffeine but in a much shorter time than filter coffee — which is usually sipped for minutes,” Milos says. “Therefore, espresso’s effect is stronger to our senses.”
Does light roast have more caffeine?
Contrary to popular belief, different coffee roasts — light, medium, or dark — have no effect on caffeine levels. “Caffeine does not get burned off during roasting,” says chef Matthew Robinson, food scientist and founder of The Culinary Exchange. “In terms of flavor, it is all in what you like. A light roast can be flavorful if you like that sort of thing, as can a very dark roast.” In theory, drinking a lighter roast instead of a darker roast before bed will do you no justice.
Espresso after dinner
“The espresso after dinner is ordered only if the meal was heavy, and they also ‘correct’ the espresso by adding grappa, known as ‘the corretto,’” Milos says of the Italian tradition. The habit might also have to do with the fact that Italians stay up later. “My experience has been that the Italians aren’t really drinking espresso before bed because they don’t have a bed time,” Robinson says.
Coffee before bed
There's no guarantee that coffee won't keep you awake. “Many factors would play into this, including baseline coffee consumption, brew method, size of the cup of coffee, bean choice, etc,” Robinson says. In other words, drinking a large latte at 10 p.m. with three shots of espresso might not be a winning bedtime drink. (A 2013 study found that caffeine consumed as much as six hours before bed significantly reduced sleep quality and quantity.) However, there’s no need to be terrified of a post-dinner espresso. Remember, it comes from coffee beans, so it isn’t as intense as you might think. “Espresso, that beautiful shot of intensity, will have the same effect as other coffees,” Robinson says.
Caffeine levels in coffee
Depending on brewing method and type of bean, caffeine levels can vary tremendously from cup to cup. “If it is weak, it might not give you much of a buzz 20 minutes before bed, but if it is strong, that buzzy feeling will kick in harder,” says Robinson. “Bean type can also be a factor — some beans have more caffeine.”
Certainly! This article delves into various aspects of coffee consumption, debunking myths and shedding light on cultural differences in caffeine tolerance. As someone immersed in the world of coffee, I can provide insights into these concepts.
-
Espresso and Roasting: The misconception that espresso requires a specific type of bean is addressed by Giorgio Milos, illy's master barista. He clarifies that any coffee bean can be transformed into espresso with the right grind. The preference for espresso or non-espresso preparations is subjective, relying on taste, balance, and aroma. The notion that espresso is inherently stronger due to a different bean type is dispelled.
-
Caffeine Concentration: While espresso has a higher concentration of caffeine per volume compared to filter coffee, the total caffeine content might be less due to its smaller serving size. The rapid absorption of caffeine in espresso affects our senses more strongly than slowly sipping filter coffee.
-
Coffee Roasts and Caffeine Levels: The belief that lighter roasts contain more caffeine is debunked. Caffeine remains consistent across roasting levels; the flavor profile depends on personal preference rather than caffeine content. Thus, opting for a lighter roast before bedtime thinking it contains less caffeine is a misconception.
-
Cultural Coffee Traditions: The practice of having espresso after dinner, especially in Italy, isn't solely about caffeine but also about cultural traditions. Italians might add grappa to "correct" the espresso, and this habit could be linked to heavier meals and a later bedtime routine. The cultural context impacts the timing and manner of coffee consumption.
-
Coffee and Sleep: The impact of coffee on sleep quality varies based on several factors: baseline coffee consumption, brew method, cup size, bean choice, and time of consumption. While a post-dinner espresso might not be as intense as feared, larger or stronger coffee servings closer to bedtime could disrupt sleep.
-
Caffeine Content Variation: The caffeine levels in coffee differ depending on the brewing method, bean type, and strength of the brew. A weaker cup might not affect sleep shortly before bedtime, but a strong one might induce a more noticeable caffeine buzz.
Understanding these nuances is crucial in appreciating the cultural, physiological, and subjective aspects of coffee consumption and its impact on sleep patterns across different societies.
