These 2 styles are similar, and often confused with each other. I was always taught that stouts were unique in that they were brewed with roasted, unmalted barley. Porters, on the other hand, differ in that they do feature barley malt. Lately, I have been reading that beer experts no longer agree universally on this point. 2 Questions- (Please feel free to answer only one, if you like.) 1. Are the lines between the 2 styles becoming so blurred that the distinction above is not enough ? 2. This one is a bit easier- Which do you prefer, Stouts or Porters ?
