Then, I started getting adventurous (more or less) with my own spice-infused homemade cold brews.
Recognizing that coffee and the associated spices are a subjective experience, I wanted to share the tracking sheet to-date for your own use (if you so desire) and to solicit any suggestions for spices/flavors that I haven't tried yet.
One limitation: I only use what the NFO already has in the house. I'm not going to buy anything custom for this hobby.
So far, the only downside to the experiments have been all the space I've taken up in our refrigerator as I try these out.
