But if the vendor has undertaken the risk, he will sustain it for so long as he has undertaken it; if he has specified no period, then he bearsthe risk until the wine is tasted, wine, of course, being regarded as absolutely sold only when it has been tasted. Consequently, either it will have been agreed how long the vendor bears the risk in the wine or, in the absence of agreement, he will bear it until the wine is tasted. If it has not yet been tasted, then, even though the purchaser may have sealed the casks or jars, we must still say that the risk is on the vendor, unless the parties have made some other agreement.
