Has anyone ever used fruit juice to flavor a beer at kegging time? I brewed a pretty basic wheat today and I am going to add key lime juice to it to make it a key lime wheat. I am not squeezing a bunch of key limes, but using the bottle of juice that you can buy when you are in Florida. I'm unsure how much to add so I don't over power it with lime. Looking for more of a starting point then adjust to taste after that. Thanks in advance!
