Totally agree with Revvy! That being said, if you know someone that does AG with a cooler set up then hook up with him/her for a brew day and watch and learn and evaluate and see if its something you want to try, otherwise stick with what you know and enjoy it!
Yup, or even better than watching, borrow it and do it yourself, and experience whether it works for you.
To be a good brewer isn't to do things one way or another, there's no magic bullet. All grain doesn't make any better or worse beers than extract, using stainless doesn't make any better or worse beers than aluminum....
What makes a good brewer is one who figures out what works best for THEM, of all the many CORRECT ways to do something, putting each little piece of the process together in a way that works for us....It's called having a process. And it's an individual thing from brewer to brewer.
And you develop it by trying things, and adding things that work, and dropping things that don't...from learning and reading, and listening and talking and sharing, and tasting.... It's not from thinking that one thing is better than another, that's why I think -vs- threads are stupid...because it's not a contest, it's just preferences.
For example, look at my bottling sticky, it's all about NOT copying me, but developing a process that works best for YOU...It's got a lot of tips to try but you ultimately have to figure out what works for you.
I'm left hand dominant ambidextrous, I write with my left, but mouse with my right....When I bottle I'm most comfortable working right to left....the empty bottles are on my right, my bottling bucket is in the middle, and when I fill them and place the cap on them I place them on the left...that works for ME....Just like using a wing capper works better for me in my PROCESS than using a standing capper... For ME, with my PROCESS, I can bottle 5 gallons in just shy of an hour. But that doesn't mean it will work as well for someone else.
