If that's true it must be some outrageously fantastic extract.
Maybe what I'll do is try the OliveNation stuff again and add more than I have been adding. I typically use only about an ounce of raspberry extract (the McCormick stuff... not the same as the LHBS stuff) in 5 gallons. Maybe I need to use the OliveNation raspberry and use more... like the whole 4oz bottle.
Yeah, that might do it. But I'm 99% certain I've been told that Lindemann's uses extract. Considering that they pretty much make raspberry pop, I can believe that.
