Have some aged sardines. More info here
What to eat with four year old sardines?
Not sure what to drink.
In a long ago post about sardines someone mentioned they liked non-alcoholic lemonade with sardines because of their affinity with citrus. i'm thinking maybe something with lemon notes.
Then again a sparkling wine might work. That would be half-way to my inclination to drink beer (post is on the beer board for beer suggestions) The vino verde suggestion would be good as they usually have a slight fizz.
