Mine are Coopers diy beer from AU. I just weighed three of them at 3.483, 3.338 and 3.370 G each. That's actually a little more variation than I would have expected. Looks like about maybe 4% so not meaningful to the brewing process, I just expected them to be closer.
I like the simplicity idea, but I would prefer more resolution if I was going to do that on a regular basis. Meaning, it's easier to raise or lower the carbonation level with measured out sugar than it is cutting up pieces of the pills. I also wonder what is all the vehicle that they are using to carry that sugar? The physical volume is far greater than what you would have if you measured out sugar and added it to the bottling bucket. So what else is in there?
