1. Get influence over local media.  Preferably control it.
2. Dominate with some obvious message, like "Bad beer is bad for your health".  Provide examples.  If none - create them.
3. When everyone agrees, push "Let's institute quality control over the beer in bars!".  
4. Send local agents to get acquainted with people, running and serving in bars.  Be smooth and friendly.  Collect info, identify black sheep: bad bars with bad beer and owners would confront you.
5. Via media institute yourself as the only acceptable quality control.  Marketing message: "Bar without our stamp of approval is bad for your health".
6. Offer quality control for bars.  Be careful with pricing or do it for free.  Check which black sheep are refusing to pay.
7. After you're set in the "market" - raise prices.
8.Violently crash and kill one or two of black sheep: they are serving bad beer anyway!
9. Lower the prices and settle with other bars who refused to pay earlier.
10. Profit!
