I own a distillery in Canada and we have the same issues with any paid digital strategy, mostly being I can’t monitor how well received anything goes as the only way for the consumer to buy the alcohol is from a monopoly, who never shares their data.

I would definitely leverage the email marketing list a lot, and if the distillery is open for tours, promote that on your Facebook as the CTA.

Also, push in the local seen. I know people lie to obsess over the digital strategy, but what makes or breaks high proof spirits in this industry is if you can get popular local mixologists and influencers the promote the product. And POS is very important in the industry. Also, events events events...
