As the Spring Festival approaches, courier services are gradually suspending operations, and many coffee lovers have already stocked up on beans in advance. But how to keep coffee beans fresh during this period has become a concern for everyone. Storing coffee beans requires avoiding three major enemies: high temperatures, moisture, and oxidation. High temperatures accelerate the loss of aroma, moisture easily leads to mold, and oxidation shortens the optimal flavor period. Front Street recommends that unopened original packaging be kept in a cool, dry place, and that an airtight container be used after opening. As for refrigeration or freezing, although it can slow oxidation, it comes with the challenges of absorbing odors and becoming damp during thawing. This article will break down these storage points in detail to help you enjoy the New Year with peace of mind. [more…]

Recent subsidy promotions on major food delivery platforms have brought consumers tangible savings, with many taking advantage of low prices to stock up on milk tea, coffee, and light bakery items. However, this seemingly win-win promotional feast has stirred up considerable unrest within Luckin Coffee stores. A large number of consumers flocked to stores to buy light food in bulk, directly causing a surge in the number of baked goods that staff need to thaw each night—work that once took just over ten minutes now takes more than half an hour. What leaves employees even more frustrated is that the company has not only canceled performance commissions on light food sales but also requires them to complete thawing tasks strictly according to procedure after closing, forcing many to work unpaid overtime. The cost of this delivery war seems to be quietly borne by frontline staff. [more…]

Does putting coffee beans in the freezer really extend their peak flavor window? Some friends have found that beans that have been frozen brew up with weaker aroma and a thin body, and so they suspect freezing is useless. In fact, freezing really can slow down coffee bean degassing and extend freshness, but only if storage and brewing are both done right. This article covers everything from airtight portioning and preventing condensation, to the two routes of brewing frozen beans directly versus brewing after thawing, and uses comparison data from Front Street Yirgacheffe · Gutingding to help you fully understand the complete operational logic of frozen coffee beans in one go.

Front Street has recently been sharing a lot about ice bock (concentrated milk), and quite a few friends are curious about how it actually differs from milk coffee made with regular fresh milk. Simply put, concentrated milk tastes richer and has a thicker mouthfeel. If you haven't tried it yourself, it's hard to imagine the texture, so you might as well make a cup and experience it. Besides buying ice bock online, you can also make it at home with just two steps: freezing and thawing. In this article, Front Street will break down in detail the principles of the freeze-concentration method, the key operational points, and separately explain the ratio strategies for using concentrated milk to make a Dirty and other milk coffees (such as lattes, flat whites, and cappuccinos)—for a Dirty, you can directly replace it in equal amounts, while for blended milk coffees, you need to adjust the amount of milk to avoid masking the coffee's flavor. It also retains product recommendations such as Front Street's classic blend and Queen's Estate SOE. [more…]

Competition among food delivery platforms has escalated into a battle of three giants, chain brands' average order values continue to decline, and Luckin's timely launch of low-priced bread vouchers has triggered a frenzy of stockpiling among consumers. However, when users take their electronic vouchers to stores for redemption, they find that baked goods at nearby stores are largely sold out, with some cities even reporting no stock citywide. This buying spree, fueled by platform subsidies, not only reflects consumers' strong demand for high-value-for-money coffee companions but also exposes brands' disconnect between demand forecasting and supply chain response. Staff explained that the thawing process and delivery cycle are the two main reasons for the redemption difficulties. For enthusiasts who love pairing coffee with baked goods, Front Street Coffee has always advocated balancing rational consumption with quality experience, and suggests paying attention to store inventory dynamics and arranging redemption times reasonably.

Freezing is a very popular method of "preserving" coffee beans in recent years. Simply seal the coffee beans and toss them into the freezer, and the flavor loss of the coffee will slow down, thus extending its shelf life. Many friends have adopted this method to stock up on coffee beans purchased during Front Street Coffee's discount events. [more…]

Front Street Coffee has frequently introduced ice bock—that is, purified milk—recently, and many friends want to know exactly how it differs from milk coffee made with ordinary fresh milk. Simply put, purified milk tastes richer, and its mouthfeel is fuller and more substantial. Besides buying it directly, you can actually easily make it at home: just freeze fresh milk and then thaw it, using the difference in freezing points among the components to remove some of the water, and you get milk with a higher concentration. In this article, Front Street Coffee will share the specific steps for purifying milk, how to judge the degree of purification, and how to adjust the ratios when using it to make milk coffees such as Dirty and latte, along with recommendations for coffee beans that pair well, to help you make a cup of rich yet not cloying purified milk coffee.

As summer tea beverage consumption heats up, Nayuki Tea has once again come into the public eye due to food safety issues. A customer in Nanchang, Jiangxi, bought a Nayuki chocolate cake through delivery and discovered two live worms inside after receiving it. After reviewing surveillance footage, the store said there were no abnormalities during the freezing and thawing stages, and pointed out that nearly three hours had passed since the order left the store, making it difficult to clearly determine where responsibility lies. The customer suspected the worms hatched from eggs, and with the two sides giving differing accounts, netizens also began discussing how to gather evidence and defend rights in food delivery cases. The incident is still awaiting a determination of responsibility by relevant departments and the delivery platform. [more…]

Nayuki Tea has once again been thrust into the spotlight due to food safety issues. The Market Supervision Administration of Jing'an District, Shanghai, recently imposed a penalty on Nayuki's Shanghai Meilongzhen Plaza store for selling expired grape-flavored cakes to consumers, with a fine of 50,000 yuan. This is not an isolated case—since its listing on the Hong Kong Stock Exchange in June this year, Nayuki's stores have repeatedly been exposed for food safety scandals such as cockroach infestations, spoiled fruit, and excessive bacterial counts. Consequently, its stock price has plummeted from the issue price of HKD 19.80 to around HKD 9, leading to a significant drop in market value. From being the "first stock of new-style tea drinks" to being plagued by negative news, Nayuki's brand reputation is facing a severe test. [more…]

Is the frozen coffee bean storage method circulating online actually able to extend the peak-flavor period and lock in the flavor? This time Front Street is going to seriously discuss this topic. Freezing can indeed slow down the oxidation rate of coffee beans, extending the optimal tasting period from 30 days to 2~3 months, but experiments show that frozen beans are actually in a "pseudo-fresh" state, and there is still a gap in flavor compared with the peak-flavor period. The real advantage of freezing lies in making the ground particles more uniform. However, there are too many variables in daily operation, such as needing to grind within one minute of thawing, adjusting brewing parameters, and improper sealing causing odor transfer. This article will break down the principles of frozen storage, the points to note, and give more practical bean storage suggestions one by one. [more…]

Starting from Front Street Coffee's actual testing, this article first clarifies the difference between freezing and refrigeration, then explains the impact of freezing on flavor, and finally offers specific operational advice such as freezing after resting, sealed portioning, and whether to thaw. If you also want to keep your stockpiled beans as tasty as possible, this article is worth reading to the end. [more…]

Bought too many coffee beans and can't finish them for a while—can you just toss them in the fridge? Should they go in the refrigerator or the freezer? This article centers on the real goal of "freshness"—preserving aroma—and breaks down the five great enemies: strong light, high heat, moisture, oxygen, and odors, while offering practical home freshness-locking solutions. It also draws on the experimental conclusions of Swiss scientist SAMO SMRKE to explain that freezing can significantly slow down coffee bean degassing and delay the peak flavor period, but improper handling can also lead to air leakage, moisture absorption, and odor transfer. At the end, Front Street's detailed freezing and thawing tips are included to help you store your beans more reliably and enjoy better-tasting coffee. [more…]

From the moment coffee beans finish roasting, their aroma is constantly changing. Right after roasting, they contain more carbon dioxide, then they enter a stage where the aroma opens up and the sweetness becomes clear, before gradually leveling off. Although fully automatic coffee machines are convenient to operate, when the beans go into the hopper still affects the crema, intensity, and aroma in the cup. On the packaging [more…]

After coffee beans leave the roaster, they continue to release carbon dioxide, and espresso extraction amplifies this change. If you open the bag immediately after roasting, the puck tends to swell rapidly when it meets water, and both the flow rate and the crema layer are more active; after resting for a few days, gas release slows down, and sweetness, body, and aroma usually come together more easily in the same cup. [more…]

Tropical fruit flavors are often the most alluring part of coffee beans: the sweet aroma of ripe fruit, bright acidity, and an aroma that unfolds like fruit juice once it hits the palate. However, these flavors are sensitive to changes over time, so when buying beans you shouldn't just look at the flavor notes—you also need to pay attention to the roast date, the condition of the packaging, and your own daily consumption rate. After roasting [more…]

When SOE espresso beans first leave the roaster, their aroma isn't immediately at its most expressive. The beans are still releasing carbon dioxide, and if they're put on the machine too soon, the puck is easily disrupted by gas, causing the espresso flow to fluctuate and the crema to puff up while the flavor stays tight. Treating the roast date as the start of a flavor calendar is more [more…]

Whether the aroma of coffee beans can cut through milk in a latte depends not only on the beans themselves but also on how many days have passed since roasting. Freshly roasted beans are still rapidly releasing carbon dioxide, which can cause uneven espresso flow and coarser foam; leave them too long, and the nutty, caramel, or fruity notes gradually fade. Catching that middle window of peak condition, [more…]

The reason home-brewed American coffee tastes good often doesn't depend solely on the bean's origin and flavor description, but also on what stage it's in. Freshly roasted beans need to release carbon dioxide, while leaving them too long causes them to gradually lose aroma. When buying beans, check the roast date clearly; when drinking them, arrange your rhythm according to their changes—often this matters more than simply chasing "the fresher [more…]
