Question
if a 40 oz of beer was opened approx. 3 months ago, but kept sealed and untouched since, is it still O.K. to drink?!

Answer
assuming the beer you are asking about is stored in the fridge:

1-if full,slighty flat,and loss of some foam head,taste ok

2-the smaller the volume of liquid in the bottle,the flatter,more decrease of foam head,and lesser degree of normal taste and flavor with some off flavors.Beer will still be safe to drink.
