The Challenge

Modern brewing operations produce a significant volume of waste by‐products composed of grains, hops, and unrecoverable liquid leftover from the brewing process. The largest by‐product of brewing is spent grains—wet grains leftover from the production of wort. This represents approximately 85% of the total by‐product. In 2018, it was estimated that 38 million tons of spent grains were produced globally.   

Pump House Group in Moncton wanted to explore food product development opportunities that would make use of their brewery wastes and beer products. Pump House Group’s operations include beer production, spirits distilling, bottling, a brewpub, two restaurants, and a taproom. Their primary focus is beer production. Their beer is sold domestically, in the USA, and in Europe. They own several notable brands, including Pump House, Crafty Radler, and Venerdi Italian Seltzer.

The Solution

A team of three �þ���Ƶ Culinary Arts Management students led by Chef-Instructor Shawn Mathews assessed the feasibility of incorporating brewing by-products as flavourings for ice cream and other frozen desserts. This team used classic culinary techniques to explore and refine recipes, serving formats, and brewery products in terms of both flavour and cost. Mathews was partially released from teaching and the students were hired as research assistants to work on this project outside of class time.

To support this project, �þ���Ƶ Instructor Wendy Nason asked her second-year Business Administration: Marketing class to conduct market research as part of their coursework. The students conducted primary research by distributing samples of the ice cream products and collecting feedback from students and staff at the �þ���Ƶ Moncton campus. The class also conducted secondary research, including a review of currently available beer-inspired ice cream flavours and an overview of the ice cream industry.

About the Collaboration

Pump House supplied the spent grains and beer flavours. Chef Shawn Mathews guided the students in the spent grain and ice cream processing and testing. The team developed some original ice cream recipes that leveraged brewery product and by-products to create original flavours. In total, three recipes were developed for three Pump House products (Muddy River Stout, Crafty Radler, Blueberry Ale) with several variations on the ingredients (chocolate, s’more, maple walnut, vegan, etc.) and format (pint, popsicle).

Marketing student research also produced several insights for Pump House, including identification of a preference for three products and preliminary indications of consumer preferences related to branding, price point, product format, and market segment.

This project was made possible thanks to funding from the Natural Sciences and Engineering Research Council of Canada (NSERC) Engage program.
