1)

(a) Abaye asked Rav Yosef whether (with regard to which B'rachah to recite over Yayin she'Hikrim) he held like Rav Yehudah Amar Rav, or like Rav Chisda.
What was the gist of his reply?

(b) What does the Beraisa say about a barrel of wine which someone uses for Terumos and Ma'asros on other barrels, and which, after a month or two, he finds has turned sour?

(c) The Beraisa uses the expression 'ha'Bodek es ha'Chavis', implying that he tastes the wine (see Tosfos).
How can he taste the wine in the barrel before having separated Ma'asros from it?

(d) What problem is the Tana concerned with?

(a) According to Rebbi Yochanan, the Tana means that for the first three days, the contents of the barrel are considered wine, and it is only from the third day on that it is considered a Safek vinegar.
Why is it considered ...

1. ... wine the first three days (and not Safek vinegar)?
2. ... Safek vinegar the last three days (and not Vaday vinegar)?

(b) How do we know that it was definitely wine at that first stage? Maybe the wine at the bottom of the barrel already tasted like vinegar?

(a) How does Rebbi Yehoshua ben Levi interpret the Beraisa?

(b) On what grounds does he consider the wine a Safek vinegar right from the beginning? In which point does he argue with Rebbi Yochanan on that score?

(c) Is there any way that he might concede to Rebbi Yochanan in this point?

(d) And on what grounds does he consider the wine Vaday vinegar from the beginning of the last three-day period? In which second point does he argue with Rebbi Yochanan?

(a) How do the Deruma'i quote Rebbi Yehoshua ben Levi?

(b) What is the problem with this quotation?

(c) We conclude that basically, Rebbi Yehoshua ben Levi concurs with Rebbi Yochanan.
Then what do the Deruma'i mean when they quote him as saying that for the first three days, it is Vaday vinegar? How do we therefore establish this case?

(d) What does Rebbi Yochanan say about this latter point?

6)

(a) What does Rav mean when he says that for the first three days following the sale, wine is considered to be in the seller's domain?

(b) Does this mean that Yayin she'Hikrim is considered vinegar?

(c) We will learn a Mishnah shortly 'ha'Mocher Yayin la'Chavero ve'Hichmitz, Eino Chayav be'Asharayuso'. Rav might well establish the Mishnah when this took place after three days.
How can we infer this from the Lashon of the Mishnah itself? What should the Tana have written had he been speaking when it occurred within three days?

(d) How else might Rav establish the Mishnah, even if it occurred within three days?

(a) What does Shmuel say about wine that turns sour even during the first three days and even in the barrels of the seller?

(b) Rav Yosef issued a ruling like Shmuel in a case concerning wine because a S'tam Mishnah later in the Perek clearly corroborates his opinion.
In which case did he rule like Rav?

(c) How does our Sugya conclude?

8)

(a) What does the Beraisa say about date-beer, barley-beer and Shemarei Yayin with regard to a B'rachah? What is 'Shemarei Yayin?

(b) What B'rachah would we otherwise have thought one recites on each of those listed?

(c) What do Acherim say?

(d) Like which Tana do Rabah and Rav Yosef rule?

(a) Rava qualifies the above Machlokes.
What will be the Din, according to him, if one added three cups of water to the dregs and four emerged?

(b) What do we mean when we comment on this 'Rava le'Ta'ameih'?

(c) And what does Rava say in a case where one poured three cups and three cups emerged? What did it taste like?

(d) How will we reconcile this with Rebbi Yehudah, who considers the wine in this very same case subject to Ma'aser?

(a) Then in which case do the Rabbanan and Acherim argue?

(b) What is the reasoning behind the ruling of ...

1. ... the Rabbanan?
2. ... Acherim?

(c) Why do we not apply the same principle in the case where one added three cups of water and three emerged? Why do not say there too, that two cups of water emerged and one of wine?
