This is the burr set with geometry intended for unimodal grind to draw the best out of lighter roasts and to highlight the flavor characteristics that are treasured in modern espresso. In October 2020, SSP has made a slight modification to make it more forgiving and adaptable for espresso usage. The Unimodal-espresso burrs work well both for filter brews and light roast espresso. SSP Unimodal burrs tend to excel in highlighting flavor clarity in lighter roast coffees. They can also work for darker roasts but we think their potential is best used for the lighter roasts. If you are someone who don’t mind experimenting and are chasing the delicate flavors in high-quality light roasted coffees, we recommend trying Turbo shots with this unimodal burrs. The high extraction of SSP Unimodal burrs tend to play well with higher-acid coffee (ie light roasts), making the acidity enjoyable even if you’re not an acidic-coffee lover. SSP’s 64 mm flat burrs were made to last a lifetime. Comprised of tool steel material coated with Red Speed Titanium Aluminum Carbon Nitride (TiAICN), you can expect these burrs to last through over 10,000 pounds of coffee before needing a new pair. SSP 64mm Unimodal Red Speed burr set increases grind speed and the extraction quality. They are designed for the Mazzer Super Jolly, Option-O Lagom P64 and many other 64mm flat burr espresso grinders e.g DF64.
