$5k to $500k (if you're Diageo)
With this aspect of marketing being the most important part of your business.
Also, operating capital looks limited. Bottles, labels, corrugated boxes, grain, botanicals?... you'll want to hold at least one quarter's worth of stock (but will be tempted to buy 1 year's worth!! given the economies of scale in everything). And remember you sell on credit. And you don't get any credit.
Wages aside. I would want a larger cash buffer, unless your overheads are non-existent.
Playing devil's advocate... Perhaps you're quite late to the party of craft distilling... I imagine in Denver it's a zero-sum game with most wholesalers, retailers and the on-trade. Selling might be tough. With this in mind, would a Distillery Pub might be the best business model? Sell at a higher GP and build a cult brand following - loyal customers. Open the bar. And build your wholesale operation as a secondary aspect of the business. At that price per square foot you're paying retail rent, not industrial rent... So a bar might make sense.
Just some ideas.
