Alcohol in Sweden
Alcohol is very expensive in Sweden; to help offset the cost of the excellent national health care, alcohol--a potential health risk--is sold at very high set margins by the government monopoly, Systembolaget, popularly referred to as Systemet--The System. A bottle of cheap gin is 200 SEK -- that's 30 USD. Because of this, many Swedes make their own alcohol using an orchestration of widely available and makeshift equipment. Note that acquiring, or god forbid, distilling this alcohol yourself is Highly Illegal and does not come with my recommendation At All.
Now comes the question of what to do with a large amount of Totally Legal Vodka you have acquired by Great Fortune. The first step is to diversify. If you live in Linköping, Hemköp in Ryd has rum and whisky essences you can add to your vodka to provide an approximation of said liquors. You will find a lot more variety of essences at Vinland--a store which you will Not have already gone to to acquire Other Equipment, in Gottfriedsberg just across Rydskögens bike trail.
Then you may want to use this product to create a tasty beverage. WILLY:s in Skaggetorp has Eldorado brand kolsyrat vatten (carbonated water) for enormously cheap, which you may want to flavor using a wide variety of flavor syrups available everywhere with the greatest variety again at Vinland. Skål!
