In a related interview: I just listened to Colin Kaminski on the BeerSmith YouTube channel. He spoke about TPO, his efforts to reduce O2, talking to the LoDo guys, using the Trifecta mix, this full malt flavor palette he gets when using it, etc.. Not a lot of detail but I thought it was interesting nonetheless.
A while back I bought but never used the OxBlox 3D blend MoreBeer sells. After listening I may replace my BtB with it in a small test batch. Given my less than stellar experience with Kmeta I won’t use it in a full batch until I am satisfied I don’t screw up a small batch first. They recommend .3 grams per gal strike water. Sounds reasonable.
