[If] he had in his heart (i.e., he intended) to take terumah of wine on behalf of wine, but what he had in his hand was vinegar, his terumah is not [valid] terumah. If he had wine in his hand, he takes terumah from the wine, and he goes back and takes terumah from the vinegar. If he had checked the barrel in order to separate [terumah] on its behalf, and then he returns and finds it has turned to vinegar: [If] three days or less [had transpired between the first and second check], it is [considered] certainly untithed produce, and from [three days and up] there is a doubt. But [as to] wine from a vat we may separate terumah on its behalf with the presumption that it remains wine for up to 40 days.
