+ another 1 on going all-grain! the basic setup is REALLY simple. I started AG brewing and skipped the extract phase altogether. I brewed 5 gallons every week for 19 batches in a row with the following items you don't need for extract batches:
8 gal AND 5 gal steel stockpot
immersion wort chiller
Papazian's "zapap" lautering tun, (converted 2 Ale Pale buckets)
strong mash spoon/paddle
you can mash at a single step or stepped-infusion style with the pot over 2 gas range burners on your stove. after mash-out, scoop the mash into your bucket-in-bucket lautering tun. drain your first runnings back into the big kettle (you have washed this out after removing the mash) because this is also your boil kettle. batch sparge (pour) your hot water into the grains, let them steep for a few, and drain those into the kettle too. THATS IT! start your boil from there, and forget that you ever opened a can to make beer! it isn't scary, it isn't hard, and it isn't really too mysterious. the benefits (which far outweigh the expenses and increased brew time) are many. you will understand beer much more than before, you will be very proud of every batch, even the s***ty ones, and you will make better beer every time since you will have a rapidly growing conception of brewing and ability to apply it. like i said, brew time goes up (5-7 hours total from set-up to clean-up) and you will need to be mentally present for all steps, but you WILL NOT REGRET IT, I PROMISE.
cheers, and tell us what you wind up doing!
