Rabbit Hole Winemaker Entrepreneur Program

In 2020, we launched an experimental winemaking program to explore new techniques and materials. Led by our own R&D Winemaker Casey Graybehl (aka The Grenachista), the Rabbit Hole program resulted in new favorites like our PezsgÅ‘ pet-nats, Pear Blanc, & Chambrusco.

In 2022, we created the Rabbit Hole Entrepreneur program to support up-and-coming winemakers bringing new perspective, energy, and wine styles to our industry. Twenty years into our own entrepreneurial adventure, our goal is to create opportunity, community, and mentorship for others just getting started. To pay forward the support, collaboration, and experiences we've had along the way, and tap into the passion and excitement of new entreprenuers that inspires and fuels our own endeavors.

The Rabbit Hole Winemaker Program is designed to provide a space for under-resourced wine styles and winemakers, and to create an incubator for the exchange of ideas.  We invite entrepreneurial winemakers to not only make their wine in the Obsidian Wine Co. cellar, but encourage them to fully participate in our Obsidian community of winemakers and entrepreneurs. 

Each year, we invite one entrepreneur to crush up to five tons of fruit at a 50% discount on custom crush services. To assist with the launch of their business, we will extend a 30% and 15% discount on years 2 & 3 respectively should we mutually agree to continue working together. 

A successful candidate for the Rabbit Hole Entreprenuer Program will have their basic business licenses, winemaking permits, and insurance in place or in progress, and be able to articulate their unique vision and goals. 

To be considered for the 2024 program, please send an email to AFTER January 1, 2024.
