Vín Valföðurs, the wine of Valföður, is eternal flow of divine intelligence.

We shall compare mythical wine of Dionisos, Baccus, Jesus, and all the other sun-gods.

Óðinn æ við vín eitt unir, –  Óðinn (/we, our true essence) needs nothing other than the flow of intelligence.

Kjöt gefur hann greyjum sínum  means: meat he gives to his wolves.
That is:  After use, body-meat goes to the dogs, Geri and Freki. Recycled Gungnis-stuff, as nothing ever dies.  The world is only change.
