This naked portafilter allows you to observe the entire extraction process, giving you visual feedback and helping you diagnose any issues with your grind size, tamping, or machine performance. For those passionate about crafting the perfect shot of espresso, this upgrade can be a valuable tool.

In this review, we'll delve into the MIAO JIN portafilter's features, benefits, and drawbacks, helping you decide if it's the right accessory for your espresso journey. We'll compare it to other bottomless portafilters available, focusing on value and performance for DeLonghi Dedica owners.

Key Features of the MIAO JIN Bottomless Portafilter

  • 51mm Diameter: Designed specifically for compatibility with the DeLonghi Dedica EC680 and EC685 espresso machines. Ensures a secure and proper fit.
  • Bottomless Design: Exposes the entire extraction process, allowing you to see the espresso channeling and make adjustments to your technique.
  • 3-Ear Design: Provides a secure and stable lock into the DeLonghi Dedica's group head.
  • Included 1-Cup Filter Basket: Comes with a 1-cup filter basket, allowing for single espresso shots.
  • Durable Construction: Made from stainless steel and wood, promising longevity and resistance to corrosion.

Pros: The Advantages of Upgrading

  • Improved Espresso Extraction Visualization: The primary benefit is the ability to visually diagnose espresso extraction issues. Channeling, spraying, and uneven saturation become immediately apparent, allowing for adjustments to your grind, tamping, and distribution.
  • Potential for Higher Quality Espresso: By allowing for better extraction analysis and correction, the MIAO JIN portafilter can help you pull more balanced and flavorful espresso shots.
  • Easy to Clean: The bottomless design simplifies cleaning compared to spouted portafilters, as there are fewer nooks and crannies for coffee grounds to accumulate.
  • Affordable Upgrade: At around $16, it offers a relatively inexpensive entry point into the world of bottomless portafilters, making it accessible to a wide range of home baristas.

Cons: Potential Drawbacks to Consider

  • Learning Curve Required: Using a bottomless portafilter requires some practice and understanding of espresso extraction principles. It can be messy at first if your technique isn't dialed in.
  • Basket Quality: The included basket, while functional, may not be of the highest quality compared to precision baskets. Some users might prefer upgrading to a higher-end basket for optimal results.

Who Should Buy the MIAO JIN 51mm Bottomless Portafilter?

The MIAO JIN 51mm Bottomless Portafilter is ideal for DeLonghi Dedica EC680 and EC685 owners who are serious about improving their espresso. If you're interested in learning more about the espresso extraction process and fine-tuning your technique, this portafilter is a valuable tool.

This upgrade is also suitable for those who enjoy experimenting with different coffee beans and grind settings. The visual feedback provided by the bottomless design makes it easier to understand how different variables affect the final cup of espresso. It's a relatively inexpensive way to gain more control over your brewing process.

However, if you're new to espresso and simply looking for a quick and easy cup of coffee, this might not be the right upgrade for you. The bottomless design requires more attention to detail and can be messier than a standard spouted portafilter.

Conclusion: A Valuable Upgrade for the Price

The MIAO JIN 51mm Bottomless Portafilter offers excellent value for money. It provides a significant upgrade in terms of extraction analysis and control, allowing you to pull better espresso from your DeLonghi Dedica. While it may require some practice and potentially a basket upgrade in the future, the benefits outweigh the drawbacks, especially considering its affordable price point.

If you're looking to deepen your understanding of espresso and improve the quality of your shots, the MIAO JIN 51mm Bottomless Portafilter is a worthy investment. Consider purchasing the MIAO JIN 51mm Bottomless Portafilter today and elevate your home espresso experience!

Its okay but honestly a bit harder to route around corners than I expected because of the armor. Signal is fine but idk if I needed it this heavy duty for just inside the house.
