I agree for large batches and if you would like to retail your liquids ,,,,,,,
Scales may have some advantages over measuring cylinders,
There is no right or wrong or superior method.
Suggesting scales is good advice for those who would like to perfect to the smallest detail,
Or those who lack patience.
scales may have a great advantage over cylinders ,,,,,for someone who would like to diy thier juice but may be put off from experimenting due to dexterity problems,
But for most new people who would like to give diy a go cylinders/measuring cups
Will suffice ,
Also be mindful but not everyone is lucky to have a money tree in thier back yard ,,,,
And that some of us we may just prefer to use a simple measuring cup or measuring spoons,
