I've never been able to brew beers like Wells Bombardier, Timothy Taylors etc. I've made some bloody great ales, and i love brewing all grain beers, but saying you can brew any beer is a bit far.
You could though, there's nothing stopping you from doing this as you have access to all the same ingredients. And because the size of the equipment is so small you can control every parameter much easier than a large scale brewery.
In saying that, i don't do this, too much effort. I'm more concerned with having a steady supply of good beer
rather than have every glass be the best beer that i've ever had. Some guys put the effort in, and i;ll tell you what, they make beer thats better than anything i've tasted in the bottle shop. In fact the first all grain beer i tasted (not mine!) was the BEST beer i'd ever tasted up until that point. It was a golden ale made by AndrewQLD on my first bundy brewday. First sip i knew that all grain was the only method i was going to brew from that point. I've put down one kit since then, it was to beef up some aussie swill i was making for xmas. What the rellos didn't drink was just emnptied out i think.
