Indeed... You especially learn to appreciate it once you're forced to drink other beers with who know what used in the brewing process... Beerlao is the only one that actually comes close to Reinheitsgebot as it only uses water, hops, yeast and barley + some polishes rice due to barley being expensive here. Other sorts are usually too sweet or just watery or tastes like shite. As for caramel - a lot of Belgian beers have that tastes; especially Trappist ones.
