From what I've heard, the main thing is to not squeeze the limes too much. After you get the main part of the juice out, don't try to get every last drop out because the last drops will not taste the same and ruin the flavor of the drink. Why? I have no idea. But I've heard this from a lot of people. And now I pass on this scientifically unverified information to you
It actually would be interesting to test if the last drops taste different from the rest to see if this is really true or not. Maybe the last drops could have a stronger taste of pulp or something? So i guess it is not true that I have no idea. I have one idea, and that is it.
