This is interesting indeed.
Being a born and raised Alberta redneck, I'm going to try and dumb things down a bit here to get a better understanding of what everyone is talking about. PLEASE correct me if I'm wrong. I'm simply trying to understand.
I understand that there is only one species of cocoa, and that is Theobroma Cocoa. I also understand that there are many "varieties" of theobroma cocoa which may or may not have evolved over 100's or thousands of years to adapt to their unique growing environments.
I also understand that there can be and often are genetic variations of beans even inside a single cocoa pod, meaning that a "variety" (aka: Nacional or Arriba for example) is often be a blend of many genetic variations from a particular region (mentioned just above).
Comparatively, there is only one species of human (homosapien), but many different races (aka: Varieties), and among those varieties many different genetic variations.
Am I wrong by using this comparative analogy?
If I'm not far off track, wouldn't it be reasonable to deduce that almost every small grower produces the rarest cocoa in the world? After all, the amount of beans they harvest don't even register on the scale of world (or even regional) cocoa production, and given the genetic varieties and associated percentages of those varieties that will present themselves in that particular harvest at that time is unique in itself (aka: rare). Duplicating that combination would be as likely as winning a lottery.
Further to that, only by combining the product of MANY growers in a region do you begin to create a "common" product which can be labelled for that region (such as Nacional or Arriba). It seems to me the only way this works, as you will NEVER get a metric ton of one single genotype, let alone many tons that represent a variety such as Nacional or Arriba.
Having said all of that, from a business perspective does the consumer really care, or is this simply a philosophical discussion amongst a bunch of chocolate geeks?
Personally, I don't think the consumer gives a pinch of pigeon poop. The mass majority of the general public still looks at chocolate as "Dark, Milk, White". The fact that single origin "Varieties" are making their way into the market and being well accepted is an indication that people are learning and becoming more discerning. I still don't think they care about the genotypes. That's more of a marketing ploy in my opinion - which is something that Maranon is using to differentiate it's product from others.
I also agree with Sebastian, that if this incredibly rare chocolate is being used by pastry chefs and other culinary professionals for baked goods and such, the flavour is questionable. In my opinion, the price of the chocolate doesn't reflect it's quality, or the quality isn't there, or it isn't being marketed correctly. Case in point: A chef isn't going to use a $90 bottle of Chiraz in a stew. He's going to use either a very inexpensive wine, or the left over wine from several opened bottles the previous day.
I do however think it's important for "chocolate geeks" and "redneck chocolate geeks" alike to learn and understand where their cocoa comes from, and how they can differentiate genotypes in order to create flavour profiles in their final chocolate, which in itself makes it unique to that geek who produces small batches of fine flavour dark chocolate. I also think it's less important to industrial chocolate makers.
Am I wrong? Am I out to lunch? Your thoughts?
