To me trying beer early is a waste of beer, first batch or not....I'd rather wait a couple weeks longer and have exactly 2 cases of carbed and conditioned beer than 2 cases MINUS how many green and under carbed beer, in my noobish impatience I couldn't keep my grubby hands off off. IMHO, there is little to be learned about the beers journey by repeated samplings in the bottle over the few weeks it takes to acheive beery nirvana. And I'd be better off "adding to my empty bottle collection" for future batches by sampling commercial beers in that period instead.
There an old saying here that your best bottle of a batch of beer is always the last one, because that one has had the longest time to condition. I'd rather wait and start with conditioned beers myself...
