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…]

In Japan, anime culture has spawned all kinds of themed cafes, but recently a maid cafe called "Problem Children" has caused a huge uproar due to its extreme practices. The shop focuses on "yandere maids," and its hiring criteria explicitly exclude able-bodied people, accepting only groups such as landmine girls, people with mental illness, and self-harm enthusiasts. Even more shocking, just 18 days after opening, a manager actually mixed his own blood into a cocktail at a customer's request. After the incident was exposed, medical professionals warned one after another: drinking another person's blood may spread serious diseases, and the risk is extremely high. Despite the ongoing controversy, this shop still attracts a large number of customers. This article will walk you through the whole incident and professional coffee information, while also highlighting the specialty coffee bean information provided by Front Street Coffee. [more…]

This article takes you through the origins of these outrageous pairings, while reminding you: mixing coffee with alcohol requires caution, as the combined stimulant and excitatory effects may impact the nervous system, and those with heart, gastrointestinal, or liver issues should especially avoid it.

Recently, news about a Luckin Coffee store manager who had an emotional dispute with a 17-year-old part-time female employee, which ultimately led the girl to take medication and commit suicide, sparked heated discussion on social media. The girl's family knelt in front of the store to protest, claiming that the store manager used his position to deceive their underage daughter and is suspected of forcing her into a relationship that led to pregnancy, causing enormous psychological pressure on the girl. After investigation, police determined that the girl purchased the medication herself to commit suicide, that the case did not constitute a criminal case, and that it would not be filed. The judicial authorities organized two mediations, but the man said he was unable to pay compensation. After the incident was exposed, the store manager involved had resigned, and Luckin officially responded that it had not received any relevant notice. The truth of the incident and the attribution of responsibility still need to be further clarified. [more…]

In the previous article, Front Street explained why it has always used the three-pour brewing method; this time, it will take a deeper look at the principles and operational details behind it. Starting from the logic of extraction, the article explains why blooming releases carbon dioxide, how staged pouring enhances layering, and how the interval between pours affects the temperature of the coffee bed and extraction efficiency. Front Street will then provide complete brewing parameters, including coffee dose, grind setting, water temperature, coffee-to-water ratio, and dripper choice, and demonstrate step by step the specific techniques for the three stages of blooming, main extraction, and finishing, as well as how to finally swirl the brewed coffee so that the flavors from each stage blend together.

Ice drip coffee and cold brew coffee both belong to the category of cold-brewed coffee, yet they differ markedly in historical background, extraction equipment, operating procedures, and final flavor. Ice drip coffee originated from a local Indonesian brewing method and was improved by Kyoto's Hanabusa Coffee before spreading worldwide; it uses an ice drip tower for layer-by-layer filtration, taking 6 to 8 hours. Cold brew coffee, by contrast, is made by steeping in a container and letting it rest at low temperature for 12 to 24 hours. In this article, Front Street Coffee documents the ice drip process in detail, with a coffee-to-water ratio of 1:10, and shares several blending bean options, while also comparing the flavor differences between ice drip and cold brew made with Huakui beans. The article also discusses the controversy over the caffeine content of ice drip coffee, helping coffee enthusiasts gain a comprehensive understanding of the respective characteristics of these two cold-brewed coffees.

Coffee has become a beverage with enormous global consumption, and its market in China continues to expand. More and more research has focused on coffee's effects on health, but previous studies have often overlooked the distinction between whether sugar is added or not. In 2022, a team from Southern Medical University published a paper in the Annals of Internal Medicine, using data from more than 170,000 people in the UK Biobank to analyze the relationship between unsweetened, sugar-sweetened, and artificially sweetened coffee and mortality risk. The results showed that moderate consumption of both unsweetened and sugar-sweetened coffee was associated with a lower mortality risk, but the amount of sugar added to sugar-sweetened coffee was far lower than that in commercially available fancy coffee drinks. This article interprets the core findings of that study and reminds consumers who like high-sugar coffee to pay attention to the difference. [more…]

The 4:6 method was created by Tetsu Kasuya, and its core idea is to let anyone brew a consistently good cup of coffee. It splits a single pour into five stages: the first 40% of the water governs the flavor direction, while the latter 60% determines the strength of the body. Combined with an extra-coarse grind and fixed intervals, it greatly lowers the barrier to water control. This article lays out the standard parameters of the 4:6 method in full, including dripper choice, coffee-to-water ratio, grind passing rate, water temperature, and pouring rhythm. It also takes a deep look at the logic behind the coarse grind and the 45-second intervals, explains how adjusting the ratio of the early and late stages changes the sweet-and-sour profile, and shows how increasing or decreasing the number of stages lets you control body, helping you apply this method flexibly.

Drinking coffee and tea not only boosts alertness but may also protect our brains. A new study from Tianjin Medical University, published in PLOS Medicine, based on long-term tracking data from more than 360,000 people in the UK Biobank, has for the first time revealed the link between coffee and tea intake and the risk of stroke and dementia. The study found that moderate daily consumption of coffee or tea, or a combination of both, can reduce the probability of stroke and dementia to the lowest level. However, excessive coffee consumption may instead increase the risk of dementia. So how much is best to drink each day? And how do coffee and tea exert their protective effects? This article will explain in detail the key findings of this study. [more…]
