Even though it has been explained that although the blight occurred after the harvesting, nevertheless he gives to him from within it—for example, sheaves that were blighted after they were harvested, which he placed to dry in the sun and they became spoiled, and he did not act improperly nor did he leave them longer than the appropriate measure; and similarly, if he leased a vineyard from him for ten baskets of grapes and they grew well, and after they were harvested they became overripe such that their taste faded and they soured, nevertheless since he was not negligent in any matter, he gives to him from these grapes—nonetheless, the Sages, of blessed memory, said that wine has a different law. For if he leased the vineyard from him for ten jugs of wine, and the wine soured while with the lessee in his barrels, even though it is known that he did everything properly, nevertheless he is obligated to buy him good wine and give it to him. This is because it is a tradition among our Sages, of blessed memory, that wine depends on the fortune of the owners, for there are those who give their fellow good wine and immediately when it comes into the hand of the recipient it becomes spoiled. Therefore, even though we explained that in this case "his own fortune did not cause it," nevertheless with wine, where the matter is known to depend on the fortune of the owners, he does not have to accept bad wine from him, and he must take good wine for him. Furthermore, it is reasonable that regarding wheat and grapes, whether they are good or bad, their name remains upon them; but wine, when it has soured, the name "wine" is no longer upon it, only "vinegar," and he is required to give him wine. Furthermore, wheat and grapes, even after their picking, still require the ground to dry out, and they are like that which grows thus from his ground; but wine in a barrel has no connection to the ground at all. And if he stipulated to give from this specific wine, everything follows his stipulation.
