The fonds is a hybrid, containing graphic materials, artifacts, textual records, and born digital records created or received by Tin Whistle Brewing Company during the production, distribution, and promotion of their craft beer line. Records include glass bottles, wooden and ceramic beer tap handles, labels, posters, signs, banners, table cards, beer profiles, t-shirts, beer glasses, bottle blueprints, gift certificates, temporary tattoos, business cards, pamphlets, awards, and digital images. Records also include digital copies of newspaper and magazine articles documenting the company's achievements.

The fonds has been arranged by the archivist into six series:
• Beer bottles and growlers (series 1)
• Beer tap handles (series 2)
• Promotional materials and merchandise (series 3)
• Awards (series 4)
• Photographs (series 5)
• Media publicity files (series 6)
