Is there a market for unadulterated, single estate, high-quality pipe tobacco? Absolutely.
Is there enough demand for a grower to actually make money on it? That remains to be seen.
High quality agricultural products are difficult and expensive to produce, hence why they command a higher price.
But somewhere along the line there is a point of diminishing returns. The comparison to high quality wine is not exactly apples to apples simply because there is a large market for high quality, single estate wine. There are a lot more consumers willing to pay a lot of money for those products. So producers know that they can command the high prices.
That isn't the case for pipe tobacco. We are very small segment of the overall tobacco market. And those that seek out "artisanal" blends are an even smaller segment of the pipe tobacco market. So in order for a grower to make any type of reasonable profit on a minimally-processed product that still tastes good that is produced in very low quantities, they would need to charge extremely high prices to the blenders. Tack on the margins from the blender to the retailer and then the retailer to the consumer, and I feel you are way above your $100.00/tin price point.
So if you're the grower, what would you choose? Growing tobacco that needs processing and casings in order to be enjoyable but with less overall effort so therefore less cost, and then selling that tobacco in large quantities at a lower profit margin but still allowing you to put more money to the bottom line?
Or, growing a tiny "exceptional" tobacco that requires the same (if not more) labor and costs to produce, and trying to sell it at exorbitant prices just to hit your profit margins and "hoping" that the product will sell to the consumer at those exorbitant prices? Because if it doesn't sell, then the retailer has to discount it and possibly sell it at a loss just because it is taking up shelf/warehouse space as well as capital. Then good luck getting the retailers to purchase it again.
I'd be all about purchasing something like that, but I would be surprised if a grower would take it on.
