and Samuel says: Wine leaps upon the shoulder of its owner.  R. Joseph decided a case In accordance [with the opinion] of Rab, in [respect of the sale of] beer;  and in accordance with that of Samuel in [respect of] wine. And the law is in agreement with [the opinion] of Samuel. Our Rabbis taught: The benediction, '… by whose word everything was made', is to be said over beer of dates, beer of barley and lees of wine. Others say [that] over lees which have the flavour of wine the benediction, '… the creator of the fruit of the wine' is to be said. Both Rabbah and R.

Raba said: All agree [in the case where] three [jugs of water] had been poured [into the lees], and four came out, that [the liquid] is [regarded as] wine; [for] Raba [is guided] by his view that any wine which cannot stand [an admixture of] three [units of] water to one [of wine], is no wine.  [In the case also where] three [jugs of water] had been put [into the lees] and three came out, [all agree that it is] no wine. Their dispute  has reference only [to the case] where three were put in and three and a half came out. [For in such a case,] the Rabbis hold the opinion [that since for the] three [that] were put in three were taken out, [only] one half is over; and one half, in six halves of water is nothing. But the others hold the opinion [that for the] three put in, [only] two and a half  were taken out, [a complete] jug, [therefore] remains over, and one jug [of wine] in two and a half [of water] [is regarded as] good wine. But how can it be said that there is a dispute [at all] in the case when more than the quantity put in [has been taken out]? Surely it has been taught:
