Gifford's Dairy, Inc.

How Grape-Nuts Ice Cream Became a Cult Favorite | Eater

"This long-running, family-owned Maine dairy has been making the cereal-based flavor from a recipe inspired by a great-grandmother’s Grape-Nut pudding for decades; it was one of the company’s earliest offerings, remains especially beloved in Maine, and is distributed as packaged ice cream to hundreds of independent shops along the East Coast and beyond." - Dana Hatic
