Formal education or hands on experience?

Hey all,

I'm coming up on a year in the winemaking industry as an assistant winemaker/viticulturist. Trying to decide next steps for my career - education or hands on experience? My goal is to work in both viticulture and enology.

I've been looking at the UC Davis online winemaking certification, but I'm not sure if it is worth the time and money vs just getting hands on experience.

I have also considered some harvest internships to get a spread of education from different wineries, but due to family obligations I unfortunately can't pack up and spend more than a few months away from home at a time.

Professionals, what paths have you taken? What are the pros and cons you've seen from each approach?
