Apologies for the long delayed response. It may be too late to be helpful. In my experience, the description of production does not need to be particularly detailed. A brief description of the major equipment – stills, storage, blending tanks, etc. whether you will be distilling, re-distilling, etc. They are mostly looking at capacity in terms of tax liability.
For the description of the tract of land I typically use the description from the property deed, and for the premises simply describe the building – type of construction and refer to the diagram for the other details. Depending on the individual reviewing the application you may be asked to provide some additional detail.
Hope this is helpful, and if it’s too late maybe helpful to someone in future.
