How much wine must be drunk to be yozie havdallah?
Answer:
Like other mitzvos performed on wine, the amount that must be drunk is a melo logmav. This is a personal amount, depending on the size of the mouth of the person making havdallah. It is the volume contained in one cheek, and can be measured by filling one’s mouth entirely with water, measuring the contents in a measuring cylinder, and halving the volume.
