If you only suck the juice out of a fruit without eating it, do you recite a blessing (Berakha) of Borei Peri Ha'es (as you would on any fruit of the tree that you eat), or Shehakkol (which you would recite on juice)?
If you extract the juice by placing it in your mouth and chewing it, then you recite the blessing Borei Peri Ha'Es, as if you were eating it. If, however, you only hold the fruit in your hand and suck the juice out of it, the blessing is Shehakkol.
There is also a difference concerning the blessing recited after drinking the juice (Berakha Aharonah). In the first case, it is treated as a regular case of eating a fruit, and requires a Kezayith (1 oz.) to be consumed within four minutes. In the latter case, however, since it is considered to be a case of drinking liquid only, we would be required to drink a full Rebi'ith (there are different opinions as to the volume of a Rebi'ith, starting from approximately 3 fluid ounces) in about half a minute. Since this is not possible when sucking juice out of a fruit, no blessing can be recited after drinking the juice, irrespective of how much juice one drank.
