Finding shared vision & passion w/ Erni Loosen, Loosen Bros

Show Notes

A great wine starts w/ an idea in your head

For successful JVs, need the right partners with real passion and the same vision

Need to see the spirit from the beginning
Has never had a business plan

JVs are not one way, but learnings on both sides (e.g. - Erni learned how to delay ripening in WA)

Erni’s goal for JV’s was not making money, but trying to create a Renaissance for Riesling, which used to be the most expensive wine in the world ~1900, but got a low quality image w/ Blue Nun and Liebfraumilch

Most partnerships structured as 50/50 and handshake deals (except Eroica is 40% Loosen, 60% Chateau Ste Michelle, which is also the only contract)
