These are the original Unimodal burrs (known as Brew burrs by SSP) that offered at the launch of Lagom P64 back in 2019.
 
The goal then was to share this unique style of espresso with our fellow coffee enthusiasts. While they can be worked to pull espresso, the 64 mm Brew burrs can be more demanding to use and hence based on our experience its usage may not be suited for everyone. When used for espresso, the puck may quickly lose its structural integrity over the course of extraction and hence channel more easily. This is a normal behavior for the grind of this burrset but as we learned it can be a suboptimal experience for those who are used to seeing well-behaved extractions. Hence, to achieve the Unimodal-style espresso more easily, a modified version SSP-Unimodal Espresso Multi-Purpose was later developed.
 
We recommend the SSP Brew (Unimodal V1) only if you’re planning to use the Lagom P64 mainly for pour over or coarse grinding, or for high brew ratio turbo-Shots. While the Unimodal V1 can be used for traditional-style espresso (9 bar, 1:2 brew ratio, 30s), it is not recommended if that’s the main intended usage.
