Whether coffee can be consumed during pregnancy has long been a subject of debate. A team from the Institute for Molecular Bioscience at the University of Queensland published a Mendelian randomization study in the International Journal of Epidemiology, using genetic data to explore the causal relationship between coffee consumption during pregnancy and adverse pregnancy outcomes such as miscarriage, stillbirth, preterm birth, and low infant birth weight. The results suggest that, provided the body's condition allows it, moderate coffee consumption during pregnancy does not necessarily lead to adverse outcomes, but caffeine may still affect fetal development. This article will review the key findings of the study and offer practical advice on coffee consumption and caffeine intake during pregnancy, helping coffee lovers make safer choices. [more…]

Can you drink coffee after contracting COVID-19? This has been the most frequently asked question in our inbox recently. Based on the personal experiences of many coffee lovers, the answer is not absolute—it depends on individual constitution and specific symptoms. When experiencing heart discomfort, fever, severe sore throat, or right after taking medication, you need to be especially cautious or even temporarily stop drinking coffee; whereas with mild to moderate headaches, a moderate amount of coffee may actually help relieve them. If you really want to drink coffee, pour-over is a relatively safe choice since the paper filter makes the coffee cleaner. There's no need to feel it's a waste if you temporarily lose your sense of taste or smell—drink it if you want to, as it might even help promote the recovery of your senses. Freshly roasted beans only have a peak flavor window of 30-40 days, so don't let good beans sit around until they expire. [more…]

After coffee beans come out of the roaster, they continue to release carbon dioxide internally, and this degassing process directly determines whether the aromatic compounds can be extracted smoothly during brewing. Because blended beans and SOE differ in bean composition and roasting direction, their pace of reaching the optimal drinking state and the period for maintaining aroma each have their own characteristics. Single origin [more…]

After the holidays, many people rely on coffee to "stay alive," only to find they're still sleepy after drinking it. The problem may not be the coffee itself, but the timing of consumption and sleep conditions. Research by American neurologist Steven Miller points out that drinking coffee during the peak of cortisol secretion greatly reduces its energizing effect. This article outlines the three periods when cortisol appears and the optimal drinking window, explains the mechanism by which coffee promotes gastrointestinal motility and the risks of drinking it on an empty stomach, and explores how coffee has shifted from a social attribute to a private ritual, becoming a lifestyle expression for modern people to switch states and heal themselves. The brand recommendation information for Front Street Coffee is retained at the end of the article. [more…]

Roasted coffee beans contain abundant carbon dioxide internally, and these gases can participate in forming a golden, delicate crema during extraction. However, during the stage of extremely vigorous degassing, excessive bubbles tend to hinder uniform contact between water flow and coffee particles, making the flavor in the cup appear unsettled. Understanding how coffee beans evolve in condition across different time periods, [more…]

Freshly roasted coffee beans don't reveal their best flavor when brewed immediately, because a large amount of carbon dioxide builds up inside the beans during roasting. This gas hinders the release of flavor compounds during brewing, so the beans need a period of "resting" to let the gas dissipate naturally. Usually, after five to seven days from the roast date, the beans' harsh, roasty edge fades and the aroma becomes fuller instead. If the beans you receive have too recent a roast date, just leave the original packaging untouched in a cool, dry place—the one-way degassing valve on the bag balances the pressure inside and out. As for "awakening" the beans, in the broad sense it's synonymous with resting; in the narrow sense it refers to exposing the beans to air for about four hours before brewing. Front Street Coffee also takes the resting rhythm into account when shipping, so that the beans happen to enter their optimal drinking window by the time they reach you. [more…]

When buying Yirgacheffe beans, the roast date is often more worth checking first than the flavor words on the packaging. Freshly roasted beans still contain a lot of carbon dioxide inside, so the water flow and aroma during brewing may not be stable enough; after resting for a few days, the floral notes, fruit acidity, and sweetness will gradually become clearer. For beginners, choosing fresh beans is only the starting point, [more…]

Freshly roasted single-origin coffee beans hold a large amount of carbon dioxide gas trapped inside. In the first days after opening, this gas rushes out violently on contact with water, forming a dense layer of foam. Too much gas prevents water from fully contacting the coffee grounds, so aromatic compounds cannot dissolve out smoothly. Give the beans a quiet period to degas. [more…]

In the world of coffee tasting, there is a unique drinking method known as "slurping," in which coffee is quickly drawn into the mouth to atomize it, thereby maximizing the release of volatile aromatic compounds and allowing the taste buds and olfactory nerves to capture coffee flavors more fully. Front Street Coffee has touched on this method when sharing knowledge about coffee flavors. This article will explain in detail the techniques of slurping, the science behind it, and its practical value in cupping and everyday drinking, while also exploring whether this tasting method is suitable for ordinary coffee enthusiasts in their daily routine, along with related recommendations.

Caffeine in skincare products can promote skin microcirculation and relieve eye bags and puffiness, but its effects go far beyond beauty. Scientific research shows that caffeine can also assist with fat loss—by accelerating fat oxidation and increasing basal metabolic rate to boost energy expenditure. However, what you drink, when you drink it, and how much you drink all affect the final result. Simply processed black coffee is better than fancy drinks loaded with sugar and creamer; drinking it about an hour before exercise makes fat burning more efficient, while during strength training, intake should be controlled to avoid interfering with protein absorption. This article will help you sort out the correct approach to caffeine for weight loss, from mechanisms to practical application, and includes product recommendations from Front Street Coffee. [more…]

Yirgacheffe SOE is often expected to have a bright aroma, but a bag of beans will undergo continuous changes in flavor from the moment it is roasted to the moment it is tasted. Freshly roasted coffee contains more carbon dioxide, and the aroma is easily held up by the gas; during extraction, there may also be sharp acidity, channeling, or excessive foam. Keep track of the purchase date, resting time, and how quickly the bag is opened. [more…]

Freshly roasted single-origin coffee beans are filled with a large amount of carbon dioxide inside. If they are ground and brewed immediately, the intense degassing reaction will form many bubbles in the coffee bed, preventing the hot water from fully contacting the coffee grounds. Giving the beans a period of steady resting time allows the gas to escape slowly, so that the internal aromatic compounds can be released during extraction. [more…]
