The Maple Syrup Digest began publishing in January 1962. While this archive contains all back issues of the Digest in their entirety, this index includes only titles of the major articles from the Maple Syrup Digest. All back issues have been reproduced here in their entirety and also contain original advertisements, event listings, and other brief items.

To search for articles on a particular topic, use your browser’s ‘find’ function (Control-F) to search for keywords in article titles (e.g.: filtering, grading, Massachusetts, etc.).

Article titles in this Table of Contents link to the issue containing the article. Click on an article title to view that issue and scroll through the issue to find a specific article. Its not possible to search within an issue.

There is a one year embargo before current Digest issues appear in this archive. To receive issues as they become available, please join your local maple association, or subscribe directly by sending $10 ($15 US if you’re in Canada) to Maple Digest, 210 Park Ave. #305, Worcester, MA 01609
