i rarely drink beer. the last time i can recall was last fall with a pizza, killian red. the time before that was last summer after cutting the grass, and in celebration i had a foster lager. at the local yuppie grocery a dispaly of single bottle beers caught my eye, and to go with the bruschetta i bought a samuel adams winter ale. it was enjoyable. my question is this, whats the difference between lager, winter ale and beer? i'll plan ahead for spring grass cutting based on the answers i get. thanks joyce
