Esplorer Cup Review: Dual-Chamber Espresso Cup That Separates Crema for Better Tasting

 Lately, I seem to keep coming back to the topic of espresso crema separation. Just as debates are heating up over whether crema should be preserved or filtered out, I came across a crowdfunded product on Kickstarter some time ago that offers a surprisingly elegant answer: young people don’t do multiple-choice questions—we want it all.

The reason this cup truly delivers on that “no need to choose” idea is its ability to offer multiple tasting experiences from a single cup. This dual-chamber espresso cup allows you to enjoy a classic espresso with crema, then—by rotating the base—separate and filter out the crema to taste an espresso without it. You can even drink it midway through the process, experiencing a uniquely balanced in-between state. Setting everything else aside, I think this cup is especially well suited for espresso tasting. On a theoretical level, we often say that crema contributes aromatic compounds, but also introduces bitterness. With this cup, you can directly compare espresso with and without crema, using real sensory experience rather than abstract discussion—and that, in itself, is a wonderful thing.

After all, I’ve never actually tasted crema and filtered espresso entering the mouth simultaneously from the middle state. Just thinking about it sparks curiosity. The cup itself is made entirely from durable Tritan™, a food-grade resin commonly used in lightweight coffee gear. The base is constructed from 304 stainless steel, while the rotating separation mechanism relies on a silicone valve. The central divider and valve allow you to separate the crema while clearly observing the entire filtration process. You can quite literally “move your tasting” between the two chambers, sampling crema, black coffee, and a standard crema-topped espresso in sequence—exploring how espresso flavors evolve across three distinct modes.

The preparation process is equally straightforward. At its core, it’s still just an espresso cup. You extract your espresso into one side of the Esplorer Cup with the valve closed. Through the transparent body, you can clearly see the cross-section of the espresso—one of the core intentions behind the design. You’ll observe how a complete espresso is layered: crema floating on top, clearer black coffee settling below, while the other chamber remains empty. At this point, you can first enjoy the espresso in its most traditional form. Then, by rotating the base to open the valve, the liquid coffee flows into the other chamber while the crema stays behind. Now you can taste the crema on its own and the filtered espresso separately, experiencing how each layer reshapes the flavor.

This cup is also designed with balance and sensory engagement in mind. The wide rim allows the coffee to flow smoothly across the tongue, enhancing body and aroma. Since the main body is made from lightweight resin, the base is reinforced with 304 stainless steel to improve stability and comfort. Its naturally ergonomic shape makes twisting, pouring, and cleaning easy. The food-grade silicone valve is both flexible and durable, and each valve is tested during production to ensure a perfect seal while still allowing smooth vertical movement.

Guangxi Coffee Explained: China’s Emerging High-Altitude Coffee Origin Beyond Yunnan

图片
 Not long ago, while scrolling through Weibo, I came across a post saying that Guangxi has started growing its own coffee . That immediately caught my attention and genuinely surprised me. Curious, I decided to dig deeper and share what I found with you. From a coffee perspective, China is actually a rather unique country. It has a complete coffee supply chain —from cultivation and roasting to distribution and consumption. China is both a coffee-producing nation and a coffee-consuming one. When people talk about Chinese coffee, Yunnan naturally comes to mind as the most well-known producing region. Over the past few years, we’ve all witnessed the remarkable transformation of Yunnan coffee. It has moved from being primarily bulk-purchased for instant coffee to embracing a mature specialty coffee path. Today, even traditionally processed Yunnan Catimor can offer a clean and pleasant cup profile, and varieties like Yunnan Geisha have also emerged, bringing greater diversity. These...

Why Water Quality Matters in Pour-Over Coffee (Alkalinity, Hardness & Flavor Explained)

图片
 The coffee we drink is, at its core, water that has dissolved the flavorful compounds inside coffee grounds. In fact, more than 98% of a cup of pour-over coffee is water. We spend so much time chasing the best origins and growing regions, the most suitable processing methods, the perfect roast profiles, and the most precise brewing techniques—yet all of these efforts ultimately rely on water to carry the coffee’s flavor. If we overlook the foundational role of water, everything else can easily fall apart. **No.1 Water Plays Two Core Roles in Coffee Brewing: Extraction and Flavor** Water is responsible for extracting soluble flavor compounds from coffee grounds, and it also makes up the body of the final beverage itself. The chemical composition of the water directly influences what ends up in your cup. **No.2 The Soluble Compounds in Water: Alkalinity and Hardness** Water contains both negatively charged ions and positively charged ions. The concentration of negatively ...

Would You Drink Coffee Made from Food Waste? The Rise of Beanless Coffee Explained

图片
 Every single second, the world consumes about 26,000 cups of coffee . On Shanghai’s Huaihai Road alone—less than two kilometers long—you can find nearly 50 cafés , each with its own style. Coffee has long since become a nationwide obsession. Enthusiasts eagerly debate bean origins, processing methods, and flavor notes, yet few stop to ask a deeper question: What hidden burden does this beloved drink place on the planet? From a food-industry carbon-emissions perspective, coffee ranks just behind beef, lamb, cheese, and chocolate . Data shows that producing a single cup of coffee consumes roughly 140 liters of water , while growing and processing one kilogram of coffee beans generates about 17 kilograms of CO₂ . Viewed through the lens of Western environmental narratives, this kind of data practically screams: ban it . How could such an “unethical” product escape scrutiny in one of the world’s environmental flag-bearers—the UK? British research has already sounded the alarm: by 20...
