Yes I did use sugar drops. with my first two batches used the plastic bottles and put a little more sugar than the directions said to. With the second batch I did get good head but still tasted like cider. With my third batch I have switched to glass 12oz bottles and used the exact amount of sugar according to the directions that came with the kit. This batch has carbonates for 3 weeks. I will give it another week at room temperasure then put some bottles in the fridge for a few days before I open another bottle.
