See the photos below of the new burrs. The SSP burrs are the same height (thickness) as the stock burrs. As others have mentioned, the SSP burrs have a tighter mounting tolerance than the stock burrs. It took some effort to get the mounting screws lined up so I could tighten the burrs down. The trick was to put in one screw at a time part way and then alternate tightening of the screws. I mentioned this to Hansung and he said the issue was with the tolerances of the mounting holes drilled by Ceado in the burr carrier. This is something SSP is aware of and they're looking at options.
I've been testing the new burrs with Counter Culture's Big Trouble and Verve's Sermon beans. The difference is really noticeable. It's easier to dial in shots with the SSP burrs. And, shots are smoother and flavors are improved. I get more chocolate notes with Big Trouble and fruitier flavors with Sermon. I've noticed several other differences:
- The grind is noticeably finer and fluffier than before. The Ceado always produced good results but the SSP burrs take things to the next level.
- The espresso grinding range has significantly expanded. The distance between zero point and espresso settings is more than double what the stock burrs provided.
- The SSP burrs produce a deeper sound when grinding and seem quieter than the stock burrs.
- Grind time has increased by 1.5-2 seconds. The Ceado burrs ground 18g in about 4.3 seconds. The SSP burrs are close to 6-6.5 seconds.
- Popcorning is almost eliminated. I assume this is due to the different burr geometry and the way beans are fed into the burrs. This makes the E37S even more attractive for single dosing.
I've only used about 2 pounds of beans since changing burrs. But, the SSP Red Speed burrs are already producing excellent results and are very consistent. I think the upgrade was well worth the expense.
