”Wine is for him both food and drink.”

To make wine, raw grapes are crushed and then fermented in a process of refinement into alcohol.

This is symbolic for the process of life that we all go through. We are crushed I many ways as both children and grown ups.
We ferment and process the experience of trauma, and turn it into wisdom.

It is not a coincidence that the product of fermentation of this kind is called Spirit.

This is what the All Father enjoys at His table.
Something of higher value enjoyed from a higher perspective.
