Fermented cacao beans-bar

I am in complete agreement with Brad here. Unless the process of making chocolate starting from the tree (what is known in the industry as tree-to-bar chocolate) is very tightly controlled from the beginning through the end you will seriously risk contamination. And even then you still might have problems. I've spoken with several chocolate makers on Hawaii and they pulled the use of or selling the fermented but unroasted cacao beans - even with their own stringent controls due to the possible contamination. Remember, the first stages of processing cacao beans happens in the tropics where there is always something in the air and the possibility of contamination. To reduce this possibility, during the ferment having high temperatures - a constant 120f and higher for several days will kill most pathogens. But, you've still got the drying process and the shipping process - contamination can happen (hot tropics).
If you choose to try and make chocolate from these fermented beans you still need to winnow and grind them to a fine particulate matter - the grinding produces heat, which you want in any case as this facilitates the cocoa butter melt which will expedite this.
And Brad is also right that cocoa powder is produced by hydraulic press - this also produces heat.
There are a couple of companies who do not chemically deodorize their cocoa butter, or they use a steam process but they are small companies and as far as I know, don't sell the cocoa butter.
I will say that the fermentation begins the process of producing the compounds that produce the chocolate flavor, this continues with the drying. Roasting is a big part of producing flavors which continues through the grinding and conching. All these steps contribute to a full rounded chocolate flavor. Steps can be omitted but only to the detriment of the final flavor.
How are you planning on grinding the cocoa nibs?
