Lets give you a brief...thingy. My mothers side of the family are pretty much all quite bad lightweights when it comes to alcohol, some of them end up unable to drink more after only about one can. However my fathers side are the opposite, and most of them can drink a lot more than my mothers side.
Then at my parents wedding one of my Dad's mates did a speech and all through it he talked about beer but he replaced the word beer with tea to take the piss out of some of my mothers family, for example he would say, "Sometimes Paul would drink barrels of tea, one after another, and keep doing so for the rest of the night" apparently all of my Dad's mates and siblings were laughing their arse off and my Mums family were just sitting there looking confused.
I was reminded of it the other day when I saw a bottle of beer and that beer was called 'tea'.
