Chapter 5
Laws Relating to Squeezing Fruit on Shabbath and Yom Tov
11.a. Juice which has oozed out of grapes on Shabbath or Yom Tov, even by itself, may not be drunk on that day.
11.b. Whether or not one may on the same day drink juice which has oozed out of other fruit by itself depends on whether or not that fruit was intended specifically for eating (as distinct from pressing).
1) If the fruit was intended specifically for eating, the juice may be drunk, and one may, for instance, drink the juice which oozes out of a grapefruit while it is being cut.
2) If the fruit was not intended specifically for eating, the juice may not be drunk on that day.
11.c. The reason for these restrictions is that, if it were permitted to drink the juice one might, on another occasion, actually come to squeeze it out.
11.d. The juice which is forbidden to be drunk may not be moved, since it is muktzeh. (See Chapter 20, paragraph 32.)
