Don't worry, the bubble's gonna pop soon anyway. All the greedy people who got into brewing to make loads of money will realize their folly and leave the industry, leaving only our passionate, insane, poor saviors.
This is more true than many think. It will take a while, but someday the surge in growth will have reached a point where the market will adjust.
The guys from Founder said a few years back that they were going to grow to be established when things got lean in the future.
the bubble is only going to break soon if you assume that themarket can only support 1 brewery per 100,000 drinkers or similar. Pre-prohibition the breweries:drinkers ratio was much higher than it is today. Even today, in many european countries that ratio is much much higher than today in the USA.
a random sampling of related media:
http://www.brewersassociation.org/insights/how-many-breweries-can-us-take/if we take the mid point between what that article poses as a reasonable level for the USA (~7100 breweries) and what a ratio in line with Switzerland (~15000 breweries) there is still quite a bit of room to grow from our current ~3100 breweries.
And we can see how the market share of the Big Ones is falling. They are huge so it doesn't seem like much at this point but it will likely continue.
There will always be adjustments in the market, saturated markets will adjust, out and out bad breweries will start to fail more often as the market matures but we are still a ways any sort of bursting bubble.
