When is he liable? When he eats a tartemar of meat and drinks a half-log of Italian wine. R’ Yose says: A maneh of meat and a log of wine. [If] he ate at a gathering for a mitzvah, [or] he ate at the [meal for the] intercalation of the month; [or] he ate maaser sheni in Jerusalem; [or] he ate neveilos or tereifos, [or] abominable or creeping animals; [(or) he ate tevel, (or) maaser rishon from which its terumah had not been taken, or maaser sheni or hekdesh which had not been redeemed;] [or] he ate something which is a mitzvah or something which is a transgression; [or] he ate any food but meat; or he drank any beverage other than wine —- he does not become a ben sorer u’moreh, unless he eats meat and drinks wine, as it says: He is a glutton and a drunkard. Although there is no proof to the matter, [there is] an indication to the matter, as it says: Be not among wine bibers and gluttonous eaters of meat.
