I brewed a close variant of this: less spec grains, less nib, no vanilla, probably more effective coffee. My vanilla beans smelled like plastic, so I didn't use them. Half the bottles got "plain" ie no coffee, half got quite a bit of cold-brewed, pasteurized, coffee. I had some plain that isn't carbonated yet; wow, so balanced. The nibs are coming through great. I am letting these babies condition to even out all the flavors. Poised to be the best beer ive brewed to date! Only wish some of the grist was roasted barley, give the nibs a bit of a roasted edge without the coffee to make it more "stouty."
