All-in-One Espresso Scale with Shot Glass Review: Smarter Workflow for Home Baristas

 When we’re pulling espresso shots in our daily routine, it’s pretty common to use both a dedicated espresso scale and a separate shot glass.But every time I go through that setup, it feels a bit cumbersome. Or maybe it’s just that there are too many tools cluttering the bar. You need a compact espresso-specific scale, plus a measuring cup—or even one with oil-filtering features. If you could combine the two into one, it would simply make more sense and be far more practical.

Some people might say, “Haven’t products like this been around for a while?” And that’s true. I’ve used similar all-in-one scales before. The key difference here, though, is that the cup and the scale are still designed as separate components, and the cup itself is made of easy-to-clean stainless steel. That alone makes it significantly more practical than some of the versions I’ve used in the past. At its core, it’s no different from a standard scale-and-cup setup—but the integrated design makes your espresso station look cleaner and helps streamline the workflow.

This coffee scale uses gravity-sensing technology to track real-time weight changes during extraction. The moment liquid starts dripping into the cup, the timer automatically kicks in. When the extraction stops and the flow stabilizes, the timer stops as well—no manual input needed. It also features a dual-range high-precision sensor system, measuring from 0.2g to 500g. It’s sensitive enough for fine adjustments, and the readings remain stable without digital drift, ensuring accuracy throughout the entire brewing process. The cup itself holds up to 100ml and includes internal measurement markings at different levels.

The scale comes with a built-in LED display and touch controls. Personally, though, I think the vertical viewing angle isn’t ideal—you have to shift your perspective slightly to read the screen while working. If the display were angled, it would be much easier to read at a glance while standing. So from a usability standpoint, this might be a small drawback for JOINOUT in terms of visibility during real-world use.

Thanks to the modular design, the stainless steel cup can also be used independently, which adds some flexibility. The device is powered by a 300mAh rechargeable lithium battery, offering up to 14 hours of continuous use. And of course, it includes the standard scale feature of switching between grams and ounces, making it adaptable to different workflows and preferences.

At the bottom, there’s a non-slip base that keeps everything securely in place during brewing. Even on smooth surfaces, it won’t slide around, helping maintain consistent measurements. There’s also an optional pure titanium cup version available—lighter, more corrosion-resistant, and with a premium feel. That said, the standard stainless steel cup is already excellent. Both options are designed with safety, durability, and a refined coffee experience in mind.

How to Choose Pour-Over Coffee Filters? A Complete Breakdown of Paper Filters, Metal Filters, and Cloth Filters

 When it comes to pour-over coffee, the soul of each cup isn’t just the beans or the brewing technique—the filtering tool you choose also directly affects the final taste. Paper filters, metal mesh filters, and cloth filters each come with their own strengths and weaknesses. Some are designed for purity and clarity, some highlight natural flavor and sustainability, and others aim to strike a balanced cup. Today, let’s break down their characteristics, usage tips, and best-use scenarios so even beginners can make the right choice with confidence.

1. Paper Filters: The Best Choice for “Clean-Cup” Beginners

As the most traditional disposable option, paper coffee filters are often the first choice for pour-over newbies. Their fine fibers trap ground coffee particles effectively, allowing clean, sediment-free coffee to drip through smoothly. More importantly, high-quality paper filters reduce coffee oils and impurities such as diterpenes, resulting in a cleaner, brighter cup with more pronounced aromatics.

Pros:

• Extremely convenient—use once and discard, no cleaning required

• Easy to switch between brands and types

• Produces clean, crisp, and pure coffee with no sediment

• Ideal for highlighting the clarity and flavor layers of the beans

Cons:

• Not environmentally friendly due to one-time use

• Unbleached filters can have a slight paper taste

• Traps most coffee oils, which can reduce smoothness and body, making the cup feel lighter and cleaner

2. Metal Filters: A Favorite of the Eco-Friendly “Pure-Flavor” Crowd

With eco-consciousness on the rise, reusable metal coffee filters—usually made of stainless steel—have become increasingly popular. They’re durable, sturdy, and eliminate the waste associated with disposable paper filters.

Cleaning tip:
Always clean immediately after use. A soft toothbrush helps remove grounds stuck in the mesh, and baking soda works well for washing away lingering oils.

Pros:

• Eco-friendly and reusable, significantly reducing waste

• Does not filter out coffee oils, preserving a richer, fuller body

• Produces a cup that tastes closer to the bean’s natural flavor

• Blind taste tests often show a clear difference compared to paper-filtered coffee

Cons:

• Larger mesh size means fine particles can slip through, causing slight grit

• Fines may cause over-extraction, increasing bitterness

• Best paired with a slightly coarser grind to minimize sediment

3. Cloth Filters: A Balanced Choice for “Advanced Brewers”

Cloth filters—commonly made of flannel and used in siphons, Chemex brewers, or traditional hand-drip devices—produce a coffee flavor profile between paper and metal. They retain some coffee oils for body while still filtering out most fine particles, giving a balanced, round, and layered flavor.

Important care note:
Cloth filters require the most maintenance. If not properly cleaned, residual oils and coffee grounds can accumulate, leading to bacteria growth and an unpleasant “dishcloth smell.” After each use, clean thoroughly with baking soda, rinse well, and store the filter immersed in clean water inside the refrigerator. Cloth filters also cannot be reused multiple times within a day, which slightly reduces practicality.

Pros:

• Flannel cloth offers excellent heat retention and filtration balance

• Produces a full, aromatic, and well-rounded cup

• Ideal for brewers who enjoy depth, complexity, and hands-on preparation

  

Quick Selection Guide

• If you’re a beginner, don’t want extra cleaning, or like clean, crisp, sediment-free coffee:
  Choose paper filters. Simple to use, consistently clean in flavor.

• If you value sustainability, want to preserve the bean’s natural flavors, and enjoy a fuller, richer body:
  Choose a metal filter. Reusable, cost-effective, and delivers the most authentic flavor experience.

• If you’re an advanced brewer, enjoy the ritual, and want a balanced cup with depth:
  Choose cloth filters. They preserve some oils while maintaining clarity, giving a layered and satisfying taste.
