I'm the kind of person who would rather make a sauce from scratch than buy a can of it, just as much for the satisfaction of it as for the quality of the result. So, when I decided I wanted to try my hand at home brewing, extract was out of the question on principle alone.
I question which "principle" you are referring?
While I mostly agree with your above statements, I do have to provide an opposing view.
Do you
always make your own ketchup from fresh raw ingredients?
Mayonnaise?
Fish sauce?
Mustard?
Hot sauces?
Marina from fresh tomatoes?
Mill your own flour?
Soup stocks starting from bones/veggies...?
Make your own utensils?
Forge your own steel for your kettles?
Blow your own beer glasses?
I know some of these arguments are extreme (and slippery slope fallacy), but for the sake of example, do you sometimes take a shortcut with a premade?
Point being, I have a lot of friends who love a good beer but many have minimal interest in brewing. So refreshing my original post in this thread, there is no wrong answer regarding extract or AG to brew or begin brewing. But ask yourself the following:
What do you hope to achieve?
What is your available time commitment?
What are you willing to invest?
What other commitments do you have that could create conflict?
How much space do you have to permanently commit?
If I were a new brewer starting from scratch with limited personal support, I would question how much I am willing to invest into a hobby that I may not continue. Dropping a grand or more on a setup used once is only nice to the guy buying it for a few hundred off of Craigslist.
