title_body: Regarding light beers and dark beers: how would you make a light beer taste more like a dark beer?
upvoted_answer: It depends upon what you think a dark beer tastes like because there is a wide range of shades of dark, and a wide range of flavors that come with dark.  The amber beers can have tastes of caramel and dark fruits like raisins.  Stouts, like a Guinness, will have roasty flavors, and those and porters can have hints of chocolate and coffee.
  
  The easiest is probably to add a little dark beer to your light beer, like you have with a half and half.   The downside here is that you open two beers when you only want to drink one, but you could always save the mix-in beer in the fridge.  You could also add come coffee, a tablespoon at a time, and see if you like it.  Or, you could cut it with, not a dark beer, but an amber colored one like an Irish Red, or a Mexican lager like a Negra Modelo, if you don't want too much of a "dark" flavor.
  
  If you really want to do it "right" and you live near a home-brew shop, pick up some caramel malt, like a crystal 40 or 60, make a little tea with it in some warm water, and add that to the beer.  That's basically what goes on in the brewing process.
