Yeah I tried it at 6 months and I was holding out much hope for 12 months, but still had to give it a cracked, get that knowledge of what the same beer can taste like after each period. Really interesting.
The last few beers I have done have been cracking beers, a couple of pale ales, amber ale and a chic porter. Really delicious beer.
Now I'm just starting to set up a BIAB system so I can give that a crack.
