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.

The Middle Valley Maple website isn't quite ready yet.

No, but it will be in the ballpark of most regular single-use plastic spouts. It isn’t any more complicated to produce than a standard spout.

When you tap in the barbed spout, do you still hear the change in tapping sounds, when you get to the right spot?

I may be wrong, but I believe they have a mark on them to indicate the depth they should be set to.

Yes, the sound change is normal as is the hammer bounce. The Barb Spout does take a little more "precision" during tapping. You want to hit it squarely, otherwise it has a slight tendency to shift from side-side as it goes in. Nothing major, but it is noticeable at time.

The video at https://www.youtube.com/watch?v=gL16D9bAbIk give a bit of information.

People have also asked if it is difficult to put Arc-Flow fittings on tubing. It is not much different than a standard fitting. See https://www.youtube.com/watch?v=TQIACHdXb_A

Lastly, when these spouts are pulled, they will often pull away some bark with them. While it may be unsightly and may appear to be of concern to some folks, it should be noted that BARK is totally dead, so you're not damaging any living part of the tree. We've monitored taphole closure, and there is no difference between standard spouts and Barb Spouts. More realistically, it's a good indicator that as long as they are put in properly they do NOT come out of the taphole...that was one of the design features after all. Even though the spout barrel is shorter, they stay in the tree.

Thank you Dr. Perkins, and as a side note welcome to Michigan., when you arrive.
