A cup of commercial espresso at the bar has its origins thousands of kilometers away at the source. Blending is not as simple as pouring several bags of roasted beans together and mixing them evenly—a professional roaster's blend is designed from the moment green beans are purchased. Understanding this upstream perspective can help shop owners see through many of the "whys" when selecting beans. The starting point of a blend is the recipe definition. [more…]

For a coffee shop that roasts its own beans, having the roaster in place is only the starting point; what truly determines the quality of the final product is the quality of the green beans and the roasting craft. Green bean costs often account for a significant proportion of initial operating expenses, so how to choose the right items, control inventory, maintain stable supply, and leverage peer cooperation to lower the threshold for acquiring specialty beans is a challenge every operator must face. Starting from the cost structure of green beans, this article sorts out the three major purchasing points for basic espresso blend beans, explores the value of establishing horizontal partnerships, offers practical suggestions for display and storage, and finally includes flavor descriptions of several Front Street espresso blend beans for coffee shops with different positioning to reference when selecting beans.

Mandheling is the iconic representative of Indonesian Arabica coffee, often simply called "Sumatra coffee." Behind this name lies Sumatra's unique geographical layout, volcanic soil, earliest harvest season, and core producing regions such as Lintong, Lake Toba, Lake Tawar, and the Gayo highlands. The article also explains how the wet-hulling process gives Mandheling its full-bodied, low-acidity flavor, outlines Indonesia's G1–G6 green bean grading standards, and explains how PWN (Pwani Coffee Company) defines "Golden Mandheling," while also retaining product information for Front Street Lintong Mandheling and Front Street PWN Golden Mandheling.

Floral aromas are a fascinating flavor dimension in specialty coffee, yet also one of the hardest for many enthusiasts to identify accurately. The floral scent of coffee is not caused by a single substance, but is the result of volatile compounds, organic acids, polyphenols in the green beans, along with the combined effects of variety, origin, processing method, roasting profile, and brewing technique. Take the natural Yirgacheffe Worka as an example: its jasmine-like white florals are fresh and delicate, and are especially common in washed light-roast beans from African and Central American origins. Understanding the mechanisms behind these aromas and the patterns across origins can help us more easily select coffees with prominent florals. Front Street Gutingting, as a light-to-medium roast washed bean, is an ideal choice for experiencing jasmine florals and a green-tea-like clarity of cup. [more…]

Recently, the National Consumers League (NCL) filed a lawsuit against Starbucks in the Superior Court of the District of Columbia, accusing its "100% ethically sourced" marketing of deceiving consumers. NCL pointed out that Starbucks emphasizes ethical sourcing commitments in its marketing, yet fails to effectively address labor abuses such as child labor and forced labor in its coffee supply chain. Since 2015, Starbucks has claimed that 99% of its coffee is ethically sourced. Although its C.A.F.E. Practices program includes multiple indicators, investigative journalists in Brazil and elsewhere have still found violations at certified farms. Starbucks responded that it will vigorously defend itself and stressed that it works with farms to ensure compliance with standards. [more…]

Is the sourness in coffee good or bad? Some people believe that sourness means the coffee is not fresh, while others regard it as a hallmark of high-quality coffee. In fact, green coffee beans themselves are rich in organic acids, most of which decompose or disappear after roasting, leaving only a limited variety of organic acids in the final cup. The latest research shows that there are not many acids that our taste buds can clearly identify, and much of the fruity acidity we perceive actually comes from the combined association of sourness with other flavors. The latest SCA cupping form classifies acidity into two categories—"sweet type" and "dry type"—helping us more accurately judge whether a coffee's acidity is good or bad. This article, from the professional perspective of Front Street Coffee, will provide an in-depth analysis of the sources of coffee acidity and the criteria for evaluating it. [more…]

When drinking coffee, you may occasionally encounter a salty taste. This is not an illusion, nor is there anything wrong with your sense of taste. Coffee itself contains four basic tastes: sour, sweet, bitter, and salty, which balance each other out. Once sweetness is insufficient, saltiness tends to emerge. The sources of saltiness are quite complex, potentially involving the processing method, coffee bean variety and altitude, defective beans, brewing water, roast level and freshness, as well as extraction technique, among other factors. Among these, espresso tends to have a more pronounced salty sensation due to the relationship between taste distribution and concentration. This article will go through the causes of saltiness one by one, while retaining Front Street brand recommendations, to help coffee enthusiasts understand and try to avoid brewing a cup of coffee with a salty taste.

Intercontinental Exchange's certified arabica green coffee inventory has plummeted to a 24-year low, totaling just 368,000 bags. More alarmingly, nearly one-third of these beans have been sitting in delivery warehouses for over a year, becoming stale coffee. This situation stems from spot prices exceeding futures prices, prompting roasters to buy directly from exchange stocks, while congestion at Brazilian ports makes replenishment with new beans a distant prospect. The combination of low inventory and the stale bean problem, compounded by global economic and financial uncertainty, has led the market to widely expect green coffee prices to remain highly volatile in the medium term.

After the COVID-19 pandemic, consumers are paying increasing attention to the environmental friendliness of coffee—from green bean cultivation to the coffee in the cup, carbon emissions are being taken into account. Coffee-producing countries and consuming countries are mostly separated by oceans, and tens of thousands of tons of coffee beans rely on air or sea freight, making fossil fuels an unavoidable source of power. The British experimental company NEW DAWN TRADERS is trying to change this situation. They charter sailing ships, abandon fuel engines, and transport green coffee beans back to the UK from places like Colombia. The voyage lasts more than five months and covers about 7,000 nautical miles. Although it takes much longer, it significantly reduces carbon emissions. At the same time, Canada's Café William and Sailcargo are also building zero-emission sailing cargo ships, with plans to put them into operation in 2023. This article will review the glorious history of sailing cargo ships and explore the possibilities of this ancient mode of transportation in the modern coffee industry. [more…]
