The old Coopers Light was a pretty fair drop for a light. I haven't tasted the new recipe Light.
Roger's Beer from Little Creatures is not bad. A close second would be Cooper's Mild Ale.
Of course, none of these stack up to a "proper" beer.
Foster's Special Bitter wasn't too bad when it was around. It was certainly heaps better than the bloody awful Foster's Light Ice. Is that really a beer?
Cheers,
Oliver
