I think you are mistaking the feedback for "bitching" rather than an illumination. "A complaining customer does more to improve business than a silent satisfied customer"
We all want microbreweries to succeed. By pointing out issues, it is the intention that those are addressed before they become problems.
The last thing we want is for microbreweries to fail within the first 3 years of being started up. A sure way to fail is to:
* not do market research prior to starting the business
* overestimate the market demand for your product
* misunderstand the distribution and goods to market plan
* fail to develop the product line fully
* overextend to early
* over promise and underdeliver
It is nice that these guys have T-Shirts, but as it stands now they are more of a T-shirt company than a brewery. Doesn't that raise a red flag?
If I were these guys I would hype up the awards (if any) that their beer has won locally, nationally, or internationally -- not what is going to be featured on the can/bottle, but what is featured in the can/bottle.
Also, in my opinion starting up a brewery by selling product in cans/bottles is not the soundest path to profitability when you are just starting up. Smaller packaging means a higher cost per unit in material, labor, distribution, etc. Doesn't it make more sense to offer product in kegs to local bars/restaurant and to set up a booth at events/festivals selling from kegs?
Criticism is tool for improvement.
