Musar for Chullin 187:19

רבא אמר

And he should not open [for a guest] casks of wine which are to be sold by the shopkeeper,<span class="x" onmousemove="('comment',' It was not unusual for a private person when about to open a barrel of wine for his table to make arrangements with a shopkeeper to dispose of that which is left after the meal; a necessary arrangement, for once the barrel has been opened the wine will in a very short time turn sour. To open up a barrel of wine for a guest without informing him of the arrangement with the shopkeeper is taking credit for something one has not merited.');">¹¹</span>
