Homebrewing - I did it for 20 years. It was a consuming hobby, in more ways than one.
Making beer at home to be as good as what you buy takes a while. Forget trying to make BudMillerCoors. There is not much flavor. But the hard part is the quality control you would need to make something taste that light and refreshing.
In 1989 one of my pale ales won the US national homebrewing contest, beating other people who went on to pro careers in the brewing industry. "Cascade Bitter" was my 15 minutes of fame.
Making pale ales or IPAs is easier because the strong malt and hops tend to mask the imperfections of your brewing process. Ditto with stouts.
Don't get in to brewing to make malt liquors or strong beers, like bocks. It is HARD to make a high-alcohol beer not taste like alcohol. The Germans do it right, though. Try a doppelbock to see.
The hobby is consuming: You will want to read everything and then start upgrading equipment and procedures. When I sold my stuff on CL, I had a four-tap dispenser with CO2 and Cornelius kegs with lots of fermenters and supplies.
I quit because I began to "need" to have two or more pints a day. Having them on tap was just too easy. The alcohol was controlling me. I weighed 25 pounds than I do today. I still drink a half-bottle or bottle a few times a week, so all is good now.
Hope this helps, and it wasn't TOO long winded.
