A very limited supply of Guatemala - Cahabón has just arrived.  These have both a bold size (see below) and bold flavor.  Big chocolate is balanced out by walnut and mildly tannic brazil nut plus a little astringency.  It finishes off with a full, lush hint of caramel.

 They are available Retail and Wholesale.  You can also try them out as Brewing cocoa.
 

And don't forget to checkout the Roasting tab for details on roasting this larger than normal bean.
