9. Jacobsen Vintage No. 1 ($1.13 per ml)
Jacobsen Vintage No. 1 represents limited edition beer created by Carlsberg. This Danish brewing giant produced it back in 2008. It was up for sale exclusively in Denmark.
This beer is made from caramel and only the finest hops. Then, it was aged in Swedish and French oak barrels inside old wine cellars for six months.
It is so exclusive that one 12-oz bottle of Jacobsen Vintage No. 1 is sold for $400. That makes it worth $1.13 per ml. The champagne-like look of its bottle makes it more exclusive.
The first batch of this beer was only 600 bottles. Many of them are now sought after in only the finest restaurants of Copenhagen.
