The Solis Maestro PLUS is based on the original and very popular Solis Maestro coffee grinder. The Maestro Plus includes all the winning features of the original Maestro grinder, plus some extras that increase its versatility and ease of use. These improvements contribute to more than a doubling of the weight over the Maestro and give the Maestro Plus a rock-solid feel and increased stability. The range of grind is 30% greater than the original Maestro. This increase is on the coarsest settings making it easier to get the perfect grind for drip and French press brewers. The number of grind settings has been increased by over 100% to 40 levels, resulting in a huge range of grinds. The key advantage of the increased settings is precision fine-tuning of your espresso grind settings. The Maestro is designed and assembled in the USA with lots of innovative features built in.
