Although one who eats a fruit recites the Beracha of "Boreh Peri Ha’etz," one who drinks fruit juice recites the Beracha of "She’ha’kol." The Ben Ish Hai (Rav Yosef Haim of Baghdad, 1833-1909), in Parashat Maseh, clarifies that this applies even if one squeezes a fruit over his mouth and drinks the juice directly from the fruit, or sucks the juice from the fruit. Since the individual in this case drinks the juice without eating the fruit, he recites "She’ha’kol." After drinking, he would not recite a Beracha Aharona, since one recites a Beracha Aharona after drinking only if he drinks a Rebi’it (3 oz.) within a specific time frame, which cannot happen when one drinks juice directly from a fruit.
However, the Ben Ish Hai writes that this is not the case when one puts the fruit in his mouth and chews it to extract the liquid. Even though he expels all the pulp from his mouth, and his intention is solely to drink the juice, nevertheless, this is considered eating, not drinking, and so the individual recites "Boreh Peri Ha’etz" before eating, and if he consumes a Ke’zayit of fruit, he recites a Beracha Aharona. This is the position taken also by Hacham Ovadia Yosef, in his work Yabia Omer (vol. 8).
Summary: One who drinks juice directly from the fruit – by squeezing the fruit into his mouth, or sucking the fruit – recites "She’ha’kol" before drinking, and does not recite a Beracha Aharona after drinking. However, one who places the fruit in his mouth to extract the juice recites "Ha’etz" before eating and the appropriate Beracha Aharona after eating (if he consumed a Ke’zayit of fruit).
