Craft Breweries, Digital Mug Club & Release-Drop Alert System
A QR-code digital mug club replaces the physical card, tracking real visit frequency to catch drifting members before they disappear for good, giving members genuine early access to limited releases before they sell out, and turning trying the core lineup into an achievement members actually want to finish.
This blueprint is free. Copy the master prompt below, build it with your own time, and the only outlay is a few low-cost tool subscriptions. Use it inside your own business, or sell it to clients. The numbers further down are what you can charge, not what you pay.

The Release Sold Out Before Their Own Mug Club Members Saw the Post
Read the articleWho you sell it to
Independent craft breweries with an active taproom and an existing or informal loyalty program (a physical mug club, a punch card, or nothing formal at all). Find them via Google Maps searches for 'brewery' or 'taproom' plus a city name, craft beer and brewery owner Facebook groups and forums, and breweries actively promoting limited releases on social media, since they're already doing the marketing work that a real alert system would make far more effective.
If you sell it, here is the money picture:
The first tile is the value of your client's own jobs, which is the reason they will pay you. The other two tiles are what you charge them.
How it works
Members sign up once and get a QR code that staff scan at the bar to log visits, replacing the guesswork of a bartender's memory with real visit-frequency data. A daily check flags any member who's crossed the drift-risk window (default 30 days, matching the industry's own return-rate benchmark) and triggers a warm, AI-personalized re-engagement message, referencing a favorite style or how close they are to completing the core-lineup achievement when that data's available. When the brewery posts a new release, mug club members get a real early-access window before the general public, turning release-day hype into an actual reason to check the app rather than hoping to catch a social post in time.
An achievement system tracks progress through the core lineup, with a real reward on completion, giving members a concrete reason to keep coming back beyond just habit.
What to expect
The visit-tracking and alert logic are reliable from day one; message tone is what benefits from the 2-week supervised pilot, since a re-engagement message that reads as genuine interest lands completely differently than one that reads as a loyalty-program bot noticing an absence. Expect release alerts to be the standout feature almost immediately, breweries running this report meaningfully faster sell-through on limited releases simply because members knew about it before the general public did. Drift-risk re-engagement is a slower build, converging over several weeks as the brewery gets a real sense of its own visit patterns.
