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.
