Tapholes: Straight or Slanted?

Is there any difference in sap yield when tapping at a slight angle (the historical recommendation) or tapping straight in (the current recommendation)? While there might be other considerations suggesting that tapping straight in is advantageous, from a syrup yield perspective, there is no apparent difference.

Identifying an Effective Defoamer for Certified Organic Maple Production

The combination of potential crop losses from foam-related incidents, reductions in crop value due to off-flavors, and ultimately the many adverse effects of such a large proportion of organic syrup with off-flavors potentially being sold to consumers, underscore the need to identify or develop a certified organic defoamer for maple production that is both more effective at controlling foam than the culinary oils that are currently used, and which results in no off-flavors when used in the quantities necessary to adequately control foam. Thus, the overall objective of this project was to identify a certified organic defoamer that met these criteria.
