But to suggest that a hundred dollar outlay vs a $1k (and that's being modest) opens one to realms unimaginable is a bit much, and I wonder of the beer can be expressed as 10 times better?
Have you tasted a fresh well made all-grain beer? If not, find an AGer near you, get pally and do so.
I spent a while at extract + extras level, and was pretty impressed with the beers I was turning out. When I made my first AG, it was a whole new level that I never knew existed (I think I got lucky with it). It made me not want to ever use extract again, it was that much better.
My AG beers are on the continual improve, and will be forever. But, having a family, mortgage and other things to do in life, I don't always have the time for an AG brewday - which is why I'm also revisiting the cans of extract, specialty grain and hops. And I'm really pleased I have.
In my beer fridge right now, the AG best bitter, lager and oktoberfest bottles stand neglected while I bash my way through a red ale made from extract + extras with a contented smile on my face.
To sum up : You can make a brilliant beer with extract, though GOOD all grain beer is untouchable by extract, in my opinion. But AG is for later down the track, after learning curves have been conquered and obsession firmly in place.
Mick C was asking if it is worth it to learn more, to become more advanced. I don't think it's in dispute that it is, but please don't read the answer as "Yes, but it'll still be crap. AG is the only way of making good beer." AG may be the
best way, but it's not the only way.
