This has nothing to do with "health nannies". It's another attack on the craft brewing industry, and at the back of it you will find the big breweries or the tavern association. Here in Montana, the microbreweries have been under constant attack by the tavern association which seems to think that they are losing a significant amount of trade to the brew pubs which are not subject to the same liquor license rules as a bar, though they are very restricted. They can for example only be open until 8:00 PM, they can't serve any drinks that they do not produce in house, no gambling, and a 3 drink limit.
A rule such as the one described here ALWAYS has a special interest behind it, and is always an attack in disguise. You can combat this sort of thing behind the scenes with diplomacy, never actually touching on the corruption, or you can grab the bull by the horns, and making a big scandal with charges of corruption, etc. By far the best way is to work behind the scenes, letting them connect the dots and leaving them a way out, a "graceful exit strategy". It needs to be done NOW, and relentlessly. The "George Bush Strategy" of bombastic words and naked threats is the worst of all strategies. Threats, accusations, and public scandal are the last resort, not the first.
