Boingboing celebrates DIY virtues with a homage to homebrewing, and amateur enthusiasm across the board:
As an amateur, you get to enjoy these small but noticeable differences. Homebrew has its own design goals, mainly exploring lots of variations that allow you to see how different beers can be. For instance, we've used fresh hops that I've grown when they're in season; we can dry the hops for use later in the year...I am proud to say that I have never brewed using the same recipe twice. It's just too much fun to try something different.
More serious home-brewers try to perfect a recipe and repeat it each time, especially those who enter competitions. But not everyone needs to have that goal. To cite a phrase made popular by Perl programmers, there's more than one way to do it. That's what makes homebrew so interesting.
