Significance - In New York state the formerly ubiquitous keg has almost instantly been replaced by large numbers of thirty-racks at almost all parties where underage people may be served. This is a direct result of the newest keg restricting legislation requiring a huge deposit, adult signature, and liability for the purchaser. Although nowhere near as cheap as a keg, thirties aren't too bad as long as you can get them at a super market, paying gas station prices for beer is a sure way to get raped.

*Forties are usually malt liquor, which is 7-8% alcohol normal beer is only about 5%.
These are just rough estimates on my own cheap beer buying experience, there is a massive difference in taste, but perhaps more importantly, alcohol content between brands and types of beers. Light beers are usually around 3.3-4.5% alcohol while beast ice (Milwaukee’s Best Ice) is 5.9% alcohol. Choose your beer appropriately, I’ve found two thirties of regular to every thirty of light beer allows for each grown-ass man to have real beer, and every whiny puss-puss can have Coors Light.
