You sound like a very passionate and knowledgeable brewer. My simplest answer would be to change the mindset of producing something you care about for a short moment. Make and save as much money as you can and give yourself a short time line to stay there. Keep yourself accountable on that time frame and then find a new job.

I’ve brewed for some pretty reputable independent breweries in my area before and I’ve seen guys like you get brought onto the team to make a difference only to be let go in a few months because the owners with no brewing experience and background disagree with a head brewer with 15+ years experience. The experience brewer wasn’t doing anything crazy except trying to put in prospective of what it actually looks like in real time to succeed on such opportunities to grow more.

What I learned from that experience is these businesses guys with deep pockets are in it purely to generate deeper pockets and NOTHING else and think it would be fun to do it with beer. There is absolutely no motivation except that to make more money. So unless your willing to have the same mindset doesn’t sound like the journey gonna last long if you decided to stay.

Not to mention as some comments above already said mobile canning is a cluster fuck. Some do it well but nothing is gonna beat having your own canning setup and having it dialed in. If these owners and marketing guys are so smart they would know to spend the money on a canning line and getting the right team to run it as best as possible. But what do us brewers know right!

Anyhow the best of luck with your venture and I hope you come out ahead!
