Very groovy. I love a black and tan and quite often do a 50/50 mix from a light and dark keg.
I don't have a turtle though
Another one of those, why didn't I think of it and market it, and I don't need it but want it :lol:
I've never really looked at the FG of the beer. I just get a hankering every now and then to do a 50/50 mix of beers of tap, to get a new flavour :lol:
I usually pour the opposite way though and have the dark on the bottom and light on the top.
