Over 2 years ago, we knew this license was coming and decided to get started. We opened two days ago, so be prepared for a long road. However, I do know there will be several more "farm distilleries" in the very near future. The deal is the Class D lets you sell both retail and wholesale, but you have to be located on a farm and must use "primarily" NY grown products. It is not entirely clear now what that really means, but currently they seem to be going with over 50% of the ingredients in each product give the NYS ABC legal dept a call for clarification. If you are really interested in pursuing this, I recommend attending the ADI conferences, the distilling training workshops run by some of the still manufacturers, and visiting lots and lots of distilleries. There are a growing number of small distilleries in the northeast, all of whom would likely welcome you visit.
Good luck on your venture.
