Yes,,you think by now GB would give us some temps since we have all tried different steps. I know Peaks is selling the GB so I went to their website to see what pour temps to use for the 444 and 449,,But Darn it anyway,,they are not selling the 423,,,I have a local supplier for the GB415 Plain Soy and she also sells the 423 BUT she doesnt have the pour temps either,,Im so FRUSTRATED!!!!!!!!!!!!!!! Okay Im done venting,,thank you,,
