Add beer to pot to delgaze, allow to reduce by at least half.
Remove pot from heat, layer ½ of the potatoes in the bottom of the pot.
Sprinkle on salt, pepper, and parsley.
Next layer on ½ the onions & garlic and ½ of the bacon.
Layer on remaining potatoes, salt/pepper/parsley, onions & garlic, bacon.

Now place the pot back on heat and bring to a boil.
