Zoepolitics has written a nice entry about beer, good and evil, and philosophy. A very interesting post and I can recommend reading it here.
I like the idea about a self overcoming of viewing beer as either good and/or evil. My own 'philosophical' view would be to regard beer from a material Spinoza sense. Which would consider the (virtual) capacity for the beer to affect (not effect) a mode/body. The consumption of beer could therefore be beneficial to one and/or a society/culture. However, there is also those immanent imperceptible becomings where one can pass a critical threshold that means the body no longer consumes the beer, but rather the beer consumes the body - alcoholism.
