when I like a beer, I just pick the Abv%, the IBU and start to play with a recipe program on my PC to try to make a similar beer.
wich malt and hops you can guess if you tasted the beer, if it's full bodied or not, the color also...
ever tried to do this? if you succeed in do a good beer similar to the one tasted, is one of the best things that happens in homebrewing.
