What Causes Buddy Syrup and What Can Be Done to Prevent it?

Buddy off-flavour is an annual, natural occurrence that has been well recognized since the dawn of commercial maple production in the late 19th century. As we began our investigation there were two basic ideas for the sudden appearance of buddy syrup. The first was that heating sap containing elevated levels of particular amino acids produced compounds (pyrazines) that contributed to buddy off flavour. A more recent idea has been that yeasts in the sap convert sulfur-containing amino acids into compounds that explain the off flavours.

Effects of Tapping Depth on Sap Volume, Sap Sugar Content, and Syrup Yield Under High Vacuum

Tapping depth strongly influences both sap yield and wounding. Numerous studies have focused on the amount of sap produced with ifferent depths, the most extensive work conducted by Morrow (1963), who found a tendency for increasing sap yields with increasing taphole depth. However, this work was conducted on gravity with 7/16” tapholes, so is less informative to most producers using 5/16” spouts and vacuum.

Maple Syrup History

This site presents ideas, current research, and new sources of information related to the history of the production and use of maple syrup and maple sugar in North America. The purpose of this site is not to be the definitive account tracing the history of maple syrup and sugar, or telling the maple story, although at times it will share old and new contributions to maple history. Rather, the focus is on the study and doing of maple syrup related history. The site will primarily feature topics and research of interest to the siteÕs creator, but on occassion the site may feature guest contributors.
