Many people have a presupposition that the wedding of Cana would have involved such a large number of people that all of the wine, miraculously made, would have been consumed during the remaining days of the event.
The text runs as follows:
Now when the headwaiter tasted the water which had become wine, and did not know where it came from (but the servants who had drawn the water knew), the headwaiter called the groom, and said to him, 'Every man serves the good wine first, and when the guests are drunk, then he serves the poorer wine; but you have kept the good wine until now.' (John 2:9, 10)
Based upon the size of the containers, commentators point out that the total wine created would be around 180 gallons. That is the equivalent of about 900 bottles. That's a lot of wine for a small wedding. However, it may not have been extravagant for a larger gathering. According to Jewish tradition, how large were weddings in Bible times?
The useful hermeneutical nature of being able to answer this question can be found in answering other questions like this one.
