Wow, funny you ask that. All along, I have been telling my gf to smell my satori in my cab. That is the exact description I said it smelt like. I'm not going to tell you thats what it will smell like after im done curing. But when she was growing thats what she smelt like.
I had a Master kush pheno that gave a minty chocolate taste on green hits. Too bad the potency was lacking or she would have remained in my collection.
Chocolpe from DNA Genetics. We had this a few years ago at Grey Area in Amsterdam. It was amazing how much like cocoa/chocolate it smelled like. I mailed some beans back and popped em but the cat ate the plants. This was while I had things torn down temporarily and the seedlings laying out.
I would also look into Tom Hills Deep Chunk and Cannacopia's Chocolate Chunk, but I don't have any personal experiences with them both.
