My wife took a sip of the Lion, looked up, and said “it's a good stout for a country where you wouldn't expect them to make stout.” I tasted it a moment later, and my conclusion was about the same. It doesn't have quite as much character or flavor as I would like, but it's a very drinkable stout. So I won't be adopting an exclusively Sri Lankan stout policy no matter how hip it would be, but I do recommend it.
We also tried the local Flat Earth Brewing Company's “Cygnus X-1 Porter,” and I would call this one a hit. Porter and stout are awfully similar- the truth is, I'm not really sure what the specific difference between them is supposed to be, although they are clearly not quite the same. This porter is a fine specimen, and particularly good for a local microbrew. I'll be trying out more of the Flat Earth beers soon, because they seem to know what they're doing when it comes to beer.
