After brewing for a couple of years myself I think that I can safely comment on the reasons to start getting into the craft. As hobbies go I think homebrewing is quite rewarding and being able to continue to develop your talents and share great beer with friends is a great motivator!
- You love beer - This one is simple and in my opinion the most important reason to ever start this hobby. If you love the tastes of beer, the smells, and the wonderful culture and history surrounding one of the earth's oldest beverages then this is the best thing in the world for you.
- You love good beer - Let's face it: There would be no point in brewing the same old BMC (Budweiser, Miller, Coors)
crapbeer that you can run down the street and pick up for five bucks. But if you just drank a Dogfish Head 90 minute IPA and then I told you that you can make that same beer at home in your kitchen given enough patience and drive and you nearly had a heart attack then this hobby is perfect for you.
- You love variety - If you love a good wheat or light ale during the hot days of the summer, an oktoberfest in the fall, and a stout in the winter and everything in between given the situation any other time then homebrewing beer is for you. Given a little planning you can always have a fresh and appropriate beer in the fridge for any occasion.
- You love to DIY - Some people have the attitude that the only people that can do anything right are themselves. Some people are right. If you have ever looked at a table and thought "I could build that better" or looked at your car repair bill and think "I could do that faster and cheaper" then homebrewing might be the hobby for you. You can tweak, experiment, and pretty much do whatever you want and the only person you'll have to blame or thank at the end of the day is yourself.
- You are a bit of a geek - Some people are just plain geeky when it comes to projects and hobbies. Brewing is in essence a science project, albeit a tasty one, that can be appreciated for it's roots in the physical sciences as well as it's results. The process of fermentation is quite a wonder to behold and experimenting with recipes, yeast strains, and temperatures can yield a tremendous amount of variety.
- You have odd beer taste or special dietary needs - One of the best parts about making your own beer is that you can put whatever you want into it. Are you concerned with pesticides and want to use only organic materials in your beer? It's possible! Do you have an allergy to something like gluten, but still want to brew beer? You can!
