Collaboration Case Study: Estelle Tracy on Educators Partnering with Craft Chocolate Makers

We recently wrapped up our four-episode series called Collaboration for Chocolate Makers, which looked at different collaboration ideas for craft chocolate companies. Today, we’re looking at a case study of a specific kind of creative collaboration within the industry to pick apart how it worked, and how you can apply it at your own chocolate operation.Estelle Tracy of 37 Chocolates is a chocolate educator whose has been a guest on Bean to Barstool numerous times (you can find links to those episodes below). She reached out to me a few weeks back to let me know about a unique collaboration she was involved in in 2025. Estelle worked with Castronovo, a popular craft chocolate maker, to release a limited chocolate bar, and then led a virtual event to tell the story of the bar. In our conversation today, Estelle talks about how she approached the pairing, how it worked, what the advantages were on both sides, and what you need to know if you want to pursue a similar collab as either a craft chocolate maker or an educator or enthusiast.Episode timeline:1:00 - Narrated introduction3:35 - Beginning of interview6:50 - Summary of Estelle's collab with Castronovo12:05 - How she pitched the collab idea14:10 - Exclusivity of collab bar21:05- Business advantage for the maker22:50 - Developing the collab bar26:20 - Collaborations between enthusiasts and makers32:15 - Things she's do differently next time36:10 - End of interview, closing thoughts on conversationMentioned in this episode:Moka OriginsAmazon Conservation TeamJ.Street ChocolateWorld Beer Cup 2026 winnersCraft Chocolat Challenge 2026 winnersRhyme & Reason ChocolateIndulgence ChocolatiersBeato ChocolatesDC Chocolate Society's Ultimate Chocolate Festival Survival GuideLucid ChocolatierPast episodes mentioned:Brewing Pastry Stouts Thoughtfully with Wandering Monsters BrewingHi Wire Brewing's 10W-40 Chocolate Imperial StoutsWolves, Sons, and Ethereal ConfectionsBrad Kintzer of TCHO ChocolateElmer Pineda of Yojoa Chocolate in HondurasFront Porch ChocolateNew Zealand Beer and Chocolate Writer Luke Owen Smith Check out David's book Pairing Beer & Chocolate: A Guide to Bringing the Flavors of Craft Beer and Craft Chocolate Together.Follow Bean to Barstool on social media!InstagramFacebookPinterestSign up for host David Nilsen's beer newsletter for regular beer musings, and the Bean to Barstool newsletter for pairings, collaborations, and maker profiles.
