METHODOLOGY
Master Miller Course
ONSITE
The course is developed through face-to-face teaching sessions developed in selected olive oil mills. In addition, some training visits will be made.
Each day an expert speaker (Master Miller) will present theoretical content, followed by an olive oil tasting session. Next, we will give a specific space for a round table, where you will be able to make questions and create debate.
The morning session will continue with a visit to an olive oil mill accredited by the Olive Oil School of Spain and end with a group meal.
After the group meal, we will make a guided tour to selected sites related to the Master Miller theme. With these trips we intend to enrich and integrate the theoretical training that is done
during the course.
Joining the experience of the master millers, together with the tastings and visits, students will acquire practical tools that they will later be able to apply in the workplace improving their results.
