Mizen 64ES: Espresso-focused 64mm Flat Burrs
 
An enjoyable espresso should be balanced, with perceived sweetness resulting from an even extraction, a velvety mouthfeel, and, most importantly, a pleasant robust finish accompanied by a lingering aftertaste. With these ideals in mind, we set out to pursue our ‘perfect’ espresso burrs.
 
The geometry of 64ES burrs initially draws inspiration from traditional-style aggressive cut burrs, which we expected to deliver intense, high body shots. Out of curiousity, we experimented with using grind bypass paths to modulate the coffee grinding dynamics. Although we couldn’t precisely isolate the impact of these grind bypass, we discovered that this burr design, when combined with our other manufacturing processes, imparted unexpectedly distinctive characteristics that we felt brought us close to that ideal espresso, and so we would like to share it with you!
The Mizen 64ES delivers sweet, softer and more balanced shots, and most importantly it is followed by a pleasant finish — an aspect that we've observed traditional-style burrs sometimes struggle with due to some extent of unintended overextraction.
 
How does the cup profile taste like?
When used for espresso, the 64ES burrs offer a coffee experience reminiscent of traditional-style espresso but with heightened sweetness, slight bump in clarity, improved balance, and a pleasing finish, all while minimizing bitterness.
 
Who are the burrs best suited for?
We designed the ES burrs with a specific focus on espresso enthusiasts—those who primarily enjoy espresso or espresso-based drinks. If you are looking to enhance the taste of your coffee (balance, finish and sweetness) without sacrificing body/mouthfeel significantly, these espresso burrs can deliver a velvety texture with minimized harsh notes or signs of overextraction. The key flavor characteristics are well-balanced, leaving a sweet and pleasant aftertaste.
 
What roast level can I use the burrs for?
We recommend these burrs for all roast levels—dark, medium, and light. However, it's not advisable for very light roasts, as they may require grinding close to zero when used for traditional shots (e.g., 9 bar, low dose, brew ratio of 1:2 or shorter).
