Using hard water will ruin your espresso machine. Soft water no higher than 50ppm is required to keep your espresso machine running for the long term. Using hard water will void the warranty.
Super soft shirt that makes some people laugh, who know me, and compliments on the design from others who do not.
Before purchasing the DM47, I used my TIMEMORE Chestnut C3S Pro Manual Coffee Grinder for all my coffee grinding. I make 72 ozs of cold brew per week with my AeroPress XL and hand-ground all the beans. After a lot of research, I chose the DM47 for the conical burrs to match the results of my TIMEMORE.
The DM47 was easy to dial in by comparing the grinds side by side. Retention is minimal as long as you use the bellow as you grind and mist your beans. Some beans will still stick, and you must have a brush or similar object to push the beans into the burs. The bar across the opening will hold some beans when pouring in 30 grams of beans, I have not had an issue with 15 grams. I turn the grinder on before dumping the beans in with a dosing cup.
Speed is excellent for my use and has cut my brewing time by half. The grinder is quiet. The cord with the transformer, due to being 12-volt compatible, can get in the way, but the cord is of sufficient length.
Clean up is easy except for the outer walls of the burrs, the section with the numbers, tens to retain ground coffee. It takes some time to clean them completely with a brush. The air puffer is ok, but does not move much air. The bellows do retain coffee grounds and are nearly impossible to clean totally.
The dosing cup will easily hold 30 grams of ground coffee.
I didn’t have a good experience with this machine. From the first week I had it, there were so many issues with grind consistency, weight, and motor overheating. Simple at home use getting ready for business, and it seems the machine I received is defective. No amount of troubleshooting or cleaning resolved the issue. Then, finally the machine stopped working entirely. I reached out to Customer service for support. Fingers crossed this can be resolved
Solid little hand grinder, magnetic catch cup is nice. Difficult to dial in grinds due to a lack of precision on the grinder dial.
