On a scorching summer day, you want to drink iced pour-over but worry the flavor will be watered down, so a friend suggests: use stainless steel ice cubes to cool down hot pour-over—wouldn't that give you both full flavor and a refreshing chill? This idea sounds beautiful, but through comparative experiments, Front Street Coffee found that although stainless steel ice cubes can preserve coffee concentration, they fall short of traditional ice cubes in temperature and mouthfeel. This article documents in detail the parameter differences between regular iced brew and the experimental iced brew with stainless steel ice cubes, the actual measured temperature results, and the inherent shortcomings of stainless steel ice cubes—slow cooling and not cold enough—to help you decide whether they are worth using in iced pour-over.

We all know that brewed coffee will naturally cool down over time, but beyond that, its flavor also undergoes irreversible changes during this process. For example, the originally rich and fragrant aroma has clearly dissipated, dark-roasted coffee becomes less smooth, medium-light roasted coffee highlights its sour and astringent notes even more, and may even develop an unpleasant [more…]

As soon as the temperature rises, iced coffee returns to the top of the sales charts. Iced pour-over lets you choose your own beans and comes with a refreshingly cold taste, making it the first choice in hot weather. However, if you simply add ice cubes to a hot pour-over recipe, the concentration gets diluted and it tastes as bland as water. The core problem to solve is: how to maintain a moderate concentration after cooling down. Using Front Street's medium-light roasted Ethiopia Kaffa Forest as an example, we've put together four highly practical iced pour-over methods—high-concentration high-extraction, ice-flushing, stirring, and ice-bath cooling—breaking down the parameters and techniques one by one, and comparing their flavor performances, to help you find the cup that suits you best.

When drinking iced coffee in summer, it tends to become diluted toward the end, so some people have thought of using stainless steel ice cubes instead of traditional ice. Are these reusable metal ice cubes really suitable for coffee? Front Street conducted an actual comparison test, analyzing the structure of stainless steel ice cubes, their cooling speed, and their impact on flavor. The results show that although stainless steel ice cubes have the advantage of not melting, their cooling effect is far inferior to homemade ice cubes, especially performing poorly in the ice pour-over step. The article also shares a pour-over plan using a mix of the two types of ice cubes, and explores why coffee shops rarely use stainless steel ice cubes. [more…]

Have you ever heard an order like this in a coffee shop—"Iced Americano, no water"? This seemingly simple drink is actually the all-ice Americano hidden behind the menu. It completely replaces the water in an Americano with ice cubes, allowing the espresso to lock in its aroma through rapid cooling, presenting a richer, more layered flavor. This article starts from Front Street Coffee's actual production and breaks down in detail the recipe ratio of the all-ice Americano, its taste differences compared with a regular iced Americano, and, combined with the concept of "extract chilling" proposed at the 2021 WBC Barista Championship, guides you to understand the flavor logic behind this way of drinking it. If you are also curious about exactly how espresso over ice is different, read on. [more…]

When drinking iced coffee, have you ever agonized over how much ice to add and how to add it properly? In fact, ice in iced coffee is far more than just a way to cool things down—it also plays multiple roles, such as locking in aroma, maintaining a low temperature, and balancing concentration. Starting from the principles behind how ice works, this article breaks down in detail the differences between solid ice and hollow ice, the advantages of refrozen ice, and, for different categories such as iced Americano, iced latte, iced pour-over, and cold brew and ice drip, provides specific ice-to-coffee ratios and Front Street brand recommendations to help you make a cup of iced coffee at home that isn't watered down and has plenty of aroma.

On a hot summer day, a glass of iced pour-over coffee becomes the favorite of many coffee lovers. But exactly how much ice should be added? And how should the coffee-to-water ratio be adjusted? This article will systematically answer common questions about iced pour-over coffee from multiple angles, including coffee bean selection, the role of ice, specific brewing plans, and the timing of adding ice. Taking 15 grams of coffee, a 1:10 coffee-to-water ratio, and 100 grams of ice as an example, Front Street Coffee breaks down in detail the grind size, actual concentration, and the impact of ice melting on flavor, helping you make a cup of iced pour-over that is both refreshing and not diluted. [more…]

On a scorching summer day, with temperatures approaching 40 degrees Celsius, would you rather pick up a glass of iced coffee or a hot coffee? Most people's instinct would be to choose a cold drink to dispel the heat, yet scientific research gives the exact opposite answer: a hot beverage may actually be the truly effective way to cool down. This article explores in depth the pros and cons of iced coffee versus hot coffee in summer from the perspectives of taste perception, the principle of ice dilution, and the body's sweating and evaporation mechanisms, and analyzes why some people insist on drinking hot coffee in the sweltering heat. Whether you are a loyal fan of iced coffee or a staunch supporter of hot coffee, this discussion about temperature and how it feels to the body is worth a read. [more…]

Iced pour-over coffee needs rapid cooling, but ordinary ice cubes melt and dilute the coffee's strength. Some friends suggested using non-melting stainless steel ice cubes, but that attempt failed; then someone else recommended dry ice, which cools quickly and doesn't cause dilution. Dry ice can indeed chill coffee rapidly without turning into water, but when it sublimates it releases carbon dioxide, which dissolves into the coffee and turns a cup of iced pour-over into carbonated coffee—essentially deviating from what's wanted. This article provides a detailed analysis of dry ice's physical properties, its everyday uses, and why it's unsuitable for making pour-over coffee, along with Front Street Coffee's key points from their dry ice experiments and a recommended bean list. [more…]

Why is iced coffee often more expensive than hot coffee?

If you want your iced pour-over to cool down properly without being overly diluted, the answer you're looking for may be here. [more…]

On a hot day, a glass of iced pour-over coffee is refreshing and invigorating. However, many people encounter two core questions when making it at home: how much coffee-to-water ratio and how much ice should be used? Does adding ice first versus adding ice later affect the flavor? This article addresses these two questions, first discussing the types of coffee beans suitable for iced pour-over and Front Street Coffee's specific bean list, then explaining in detail the reference ratios of coffee, water, and ice, as well as the subtle differences in taste between adding ice first and adding ice later. Finally, it supplements two rapid cooling methods that do not dilute the concentration, helping you make a cup of iced coffee that has both aroma and refreshingness. [more…]

The biggest difference between iced pour-over and regular hot pour-over is the introduction of ice as a variable. Ice does not participate in the extraction, so it is necessary to rebalance the grind size, coffee-to-water ratio, and pouring technique. Through brewing practice with multiple beans, Front Street Coffee has summarized an easy-to-control approach of a 1:10–1:12 coffee-to-water ratio and a 1:5 coffee-to-ice ratio. Taking 15 grams of coffee as an example, that means 150 grams of water and 75 grams of ice. The grind size needs to be adjusted finer to compensate for the shortened extraction time. When pouring, reduce the flow rate and increase the number of pours, keeping the total time between 1 minute 40 seconds and 1 minute 50 seconds. In terms of bean selection, light-to-medium roasted flavor-focused coffees better showcase the refreshing quality of iced brewing, while dark-roasted beans tend to produce a thinner mouthfeel and reduced balance.

Americano is usually made by diluting espresso with water, but there is a special approach—adding not a single drop of water, and instead using only ice cubes to replace the water portion. This is what is known as an "all-ice Americano." A barista at Front Street Coffee once encountered a customer who specifically asked for an "iced Americano, no water." What exactly makes this way of drinking coffee so special? This article will walk you through how an all-ice Americano is made, the WBC competition concept it draws on—Extract Chilling—and how it actually differs from a regular iced Americano in terms of concentration, bitterness, and aroma layering, helping you decide whether this water-free iced Americano is worth trying.

As temperatures rise, iced coffee returns to the top of the sales charts. Iced pour-over lets you freely choose your favorite beans while offering the sweet, refreshing taste of a chilled brew—making it an excellent way to beat the heat. But the key to making a delicious iced pour-over lies in solving the problem of dilution after cooling. Front Street Coffee has put together four zero-threshold iced pour-over brewing approaches—high-concentration high-extraction, ice rinsing, the stirring method, and ice-bath cooling—each with detailed parameters and step-by-step instructions, demonstrated using a light-to-medium roast Ethiopian Kafa Forest as an example. No matter what equipment you have on hand or what size your ice cubes are, you'll find a method that suits you. [more…]

“Hey handsome! One iced americano, and make it the kind without water.” This was a request a barista at Front Street Coffee once received. Although Front Street has quite a few secret menu items (such as Flat White and Dirty), hearing this request still caught them a little off guard. [more…]

On a scorching summer day, when you crave iced coffee but don't want to give up the full flavor, many enthusiasts consider brewing hot coffee first and then adding ice to cool it down. While this method is feasible, it tends to make the coffee taste weak. This article uses a real test case of Front Street Coffee's Finca Diviso·Geisha to illustrate how the concentration drops from 1.49% to 1.09% before and after adding ice to a hot pour-over, as well as the noticeable decline in taste and flavor. At the same time, the article also offers adjustment ideas for iced pour-over: change the grind size from a 20-mesh sieve passing rate of 75%~80% to 80%~85%, change the coffee-to-water-to-ice ratio to 1:10:6, and keep 15g of coffee, 92°C water temperature, a three-stage pour, and a 2-minute extraction. This way, you can achieve a refreshing taste while retaining flavors such as grape, passion fruit, and apricot, presenting a full-bodied juicy mouthfeel. [more…]

Americano may look like nothing more than espresso with water, but how much water you add and what ratio you use directly determine whether a cup tastes good. This article focuses on the water-to-espresso ratio for Americano, explaining what water-to-coffee ratios suit coffee beans of different roasting styles and flavor profiles, and using a classic Italian blend as an example to give a reference range of 1:7 to 1:8. The article also breaks down in detail the specific parameters Front Street Coffee uses to make iced Americano: 40g espresso, 100g large ice cubes, and 120g water, i.e. 1:2.5:3, and further introduces the preparation order for the hidden menu item "all-ice Americano" — put the ice in first, then pour in the espresso, using the principle of extract cooling to lock in aroma and speed up chilling, for a better mouthfeel and flavor performance. [more…]

Walk into any chain coffee shop, and just the Americano alone can give you a case of choice paralysis—regular ice, less ice, no ice, and even the secret-menu full ice. These seem like nothing more than differences in the amount of ice, but in reality they fundamentally change a cup of coffee's strength, aroma direction, and mouthfeel. This article will break down, one by one, the key preparation points and taste characteristics of four ice-level Americanos, from the ratio logic and operating steps to the final flavor, and will use Front Street Coffee's commercial blend as the unified test bean to help you make the cup that suits your taste, whether at home or in a shop.
