super interesting! I realized how important water is when I brought my coffee setup to different countries and tasted the same coffee with very different water. sometimes it was incredible, and other times it tasted really bad even though they were the same beans from the same batch. wild!
Can you say more about how you're mapping from recipes (say on the Lotus website) to the post-brew method? For example say the Light and Bright with 300ml would be 2 drops calcium and 2 drops Potassium. Would you add those same drops to the finished brew or are you making more adjustments than that? I really like the idea of simplifying the workflow with drops added directly to a finished cup, so thank you for sharing this!
You can't use the same number of drops for a pre-brew vs post-brew experiment, otherwise the mineral concentrations will be very different. For the experiment we scaled up (doubled) our pre-brew recipe by 2x and measured the amount of water we needed from it. This is because the difference in the volume of water between pre and post brew is slightly different, but not different enough to necessitate a different number of drops (per the recipe calculator).
I disagree about morning complexity. The best part is not easily making a perfect morning cup, although it is - no, it is making the incremental changes to continually improve with skill and luck so you've optimized by the second to last cup of that bag, which you repeat on the final cup. The goal is a consistent optimal before the bag runs out - it's not easy - therefore a worthy goal.
