A new brand launch is always exciting! I have seen plenty that worked and at least as many that should have but didn't.

Are you suggesting shipping your cognac in a decanter? If so, you might want to consider the purpose of a decanter. Liquor products (wine in particular) have natural sediments that collect over time. Decanting prior to serving separates these sediment, aerates the product (again, particularly relevant for wine) to enhance the flavor, further enhanced by prolonged exposure to air (more relevant for cognac). Being in a decanter at the point of sale is counterintuitive. At that point the decanter is just a fancy shaped bottle. If your product is at the entry point of the cognac market, it might make sense for someone in need of a decanter at home. Once purchased, however, there would not be any need to purchase from you again.

Other considerations are costs associated with automated filling, odd-sized packaging and recycling standards - all of which add up to increased costs.

A better idea might be to use standard bottling sizes but include marketing literature offering a free or discounted (branded?) decanter for anyone subscribing to your cognac "club" or newsletter. Build out your customer base and keep you product out of the discount bin.

If this is an avenue you want to pursue, let's arrange a call and I will offer up some strategies specifically tailored to your launch and market entry.
