They say that no one has ever tasted the best beer in their life until they taste all kinds and flavors, even the rarest kind of all. There are a number of rare beers that beer-lovers can only see in their dreams and fantasies. These are the kinds of beer products which are produced in such a low number that finding it is like looking for a unicorn's hair or a phoenix feather. So what and where are these rare beers?

The Bruery Barrel-Aged Partridge in a Pear Tree - This particular beer is so rare that there are only about 290 bottles produced. According to a report from Esquire Magazine, a company called The Bruery, has come up with a plan to create 12 different flavors of limited edition beer that would represent the elements of the song 'Twelve Days of Christmas'. The 'Partridge in a Pear Tree' was the first of many installments which started out in 2009, there had only been eight released so far.

As funny as its name may sound, drinking it will probably feel like getting and opening gifts on Christmas morning. But who knows? It's a wonder who has tasted, or even seen, all twelve beautiful creatures.

Clapton Craft NW5 - A report from Metro UK has indicated that this particular limited edition beer is one of the world's rarest and most sought-after flavors of beer in the world. It is so rare that it has only reached the United Kingdom once and only a total of 100 bottles were sold.

It was so widely sought after that the report even noted that other beer-lovers had resorted to buy the empty bottles. A collectible of the most interesting kind, the Clapton Craft NW5 was produced and brewed in Kentucky USA.

Sapporo's Space Barley - If you have never heard of an extra-terrestrial beer then there you have it. The Sapporo's Space Barley is the world's first beer ever brewed from zero-gravity barley. This is the kind of barley which has been grown on the International Space Station. A report from Gizmodo has noted that there are only 100 liters of this ever made turning it into the most expensive and sought-after beer in the world.
