The UVM PMRC report on the Barb Spout results is at:
https://www.themaplenews.com/story/p...t-results/473/
Briefly, in our research we found a 12.2% increase with the Barb Spout in one study and a 10.3% increase in the other compared to control spouts. A cooperating maple producer and equipment supplier in Ohio (where they had very good conditions this year) had a 36% increase with the Barb Spout.
