It seems that walmart has those round igloo coolers in 7 gallons as opposed to 5 or 10 gallons for $28.88. What do you think, if I want to brew 5 gallon batches and brew some "big" beers. And by the way, could someone give me a definition of big beers because I take it as a high gravity beer, but does it also mean a high alcohol beer? What styles would be considered a big beer (porter, stout?)? Thanks!
