I've noticed the last several bottles with non-dissolving chunks at the bottom of the jar, and these end up as unappetizing junk in the bottom of your glass. The quality seems to have gone down a lot, and who knows what these chunks really are? They don't look like pieces of lemon, but like solidified "chunks" of something. Realemon used to dissolve and stay in suspension in the refrigerator, perhaps with one shake when the bottle was opened. But now with "chunky" bottles you have to shake hard every time you want a squirt in your glass or you just get the clear part that tastes flat and not like "real lemon." When you shake, the "chunks" come out since they don't dissolve and then they don't stay suspended in solution. Anyone else notice this? At first I thought this was normal, but the store brand stays suspended without shaking, and there are no "chunks" at the bottom of the bottle. I'm switching since Motts no longer is concerned about product quality, and "chunks" may even be bad for you.
