Ok, so it seems bottling/labeling is pretty low cost, at somewhere between $0.50 to $1.00.
Bottle shape is very standard, so no retooling of equipment.
How much should one pay a distiller to proof down 10 barrels? And how labor intensive is this process at the end of the day and does it really require much skill?
Thanks everyone so far for the comments, this is helpful, and I am a neophyte on this aspect of things. Thanks for being patient.
