“What the…?” or “Office mystery”

This is:

• water tapped from a rather MUDDY ice mountain?
• cider from Holloween 1997?
• a frothy brew of raspberry ice tea that sounds really good but looks questionable?
• a rich lager imported from Germany beneath SAU alcohol radar?
• the urine sample of a REALLY dehydrated person (I’m sorry…that was quite bad…)?
