Probably you can take the offer, but your education on coffee should be excellent. Build confidence so that you can have the training and work with the roaster to gain expertise and experience in latte making. Having an independent coffee education is phenomenal. Have an expert to train your employee to make them understand the concept of preparing beverage and acquire the skills of creating a consistent drink at any time.
The aim of the majority of the coffee companies that offer the training is to entice individuals to choose the products they provide over a competitor. The sales department will understand what it means by proper preparation, and the information is directed briefly to the owner of the shop who is then left with the task of training the new staff without putting in place the core benefit of thorough training.
