Recently, a distinctive coffee creation has been trending online—the white toast Dirty. It isn't made by adding toast to coffee; instead, milk that has been soaked with toast is used to make the Dirty, giving the milk both the aroma of bread and a richer mouthfeel. In this issue, Front Street Coffee replicates this drink, using raw toast soaked in a 1:5 ratio under refrigeration for 4 hours, then filtering it and pairing it with a specialty espresso blend, documenting the complete process of temperature contrast and flavor integration across three sips. However, Front Street also specifically warns that fresh bread is prone to mold, and soaking it in milk for a long time will greatly accelerate spoilage, posing safety risks if not handled properly, so friends with sensitive stomachs are advised not to try it casually.

In recent years, more and more coffee enthusiasts have chosen to buy their own espresso machines at home, starting with espresso and gradually mastering the preparation of drinks like lattes, latte art, and dirty coffee. Recently, a netizen tried to recreate the butter latte commonly seen in coffee shops at home. To skip the wait for butter to soften at room temperature, they had a sudden idea: put a block of butter directly into the portafilter and tamp it together with the coffee grounds for extraction. This method sparked a nationwide copycat challenge, but the results often ended in failure—the butter was squeezed into thin strips by the pressure and shot out from the bottomless portafilter, coffee liquid splattered everywhere, and the countertop was left in a mess. Onlookers joked that the espresso machine had switched careers to become a pasta maker. This article fully documents the process of this creative experiment, the real feedback from netizens, and warm reminders from experienced individuals. If you're also tempted to try it, you might want to first read this compilation by Front Street Coffee before making a decision. [more…]

So if we want to make [more…]

Dirty and iced latte are both combinations of cold milk and espresso, and because they look similar and use the same ingredients, they are often lumped together. But the two have significant differences in cup size, whether ice is added, cup temperature, the purpose of layering, and the way they are drunk. Dirty emphasizes taking a big gulp and experiencing the interwoven layers of hot and cold, bitter and sweet, while iced latte needs to be stirred evenly before enjoying its balanced taste. When making a Dirty, the choice of coffee beans is crucial. Front Street recommends medium-dark roasted blends or single-origin SOE beans to highlight caramel and chocolate flavors, and medium-light roasted beans can also be used to obtain fresh fruity notes. This article will, from Front Street's professional perspective, break down one by one the differences in making and tasting points between Dirty and iced latte. [more…]

It also retains product recommendations such as Front Street's classic blend and Queen's Estate SOE. [more…]

Ordering an iced Flat White at a specialty coffee shop is often politely declined by the barista, which leaves many enthusiasts puzzled: it's understandable that a Dirty can't be made hot, but why can't a Flat White be made iced? To answer this question, we first need to understand exactly what kind of espresso milk coffee a Flat White is. Its cup size is on the small side, its milk foam is extremely thin, and its signature feature is precisely that layer of flat microfoam less than 0.5cm thick. Starting from the actual situation of Front Street Coffee's store menu, this article sorts out the core differences between the Flat White, Latte, and Cappuccino in terms of cup size, milk foam thickness, and flavor balance, explains why an iced drink cannot present the Flat White's unique charm, and why it easily degenerates into a product indistinguishable from a small cup of iced latte.

The same coffee beans can present completely different flavors depending on the extraction method. Take Front Street Indonesia Mandheling, a medium-dark roast, as an example: when brewed as pour-over, it is mellow and gentle, with notes of caramel, herbs, and spices; if instead made into espresso with a coffee machine, it develops a rich layer of crema, releasing layers of dark chocolate, cream, and roasted nut aromas, and when drunk straight it is intense and stimulating with a pronounced roasted note. This shows that choosing coffee beans cannot be done casually; you need to consider the extraction method, roast level, and freshness. Fresh beans are rich in carbon dioxide, and together with the porous structure of a dark roast, they make it easier to extract a large amount of crema and roasting aromas such as chocolate, cocoa, butter, cookies, and caramel. For beginners, value for money is especially important. Below are five of the most popular espresso blends, covering Front Street Specialty Blend, Commercial Blend, Dark Cocoa Blend, and Classic Blend, along with their respective suitable scenarios and flavor characteristics, for reference whether for opening a shop or home use.
