Based in Dublin, the Guinness brew is a malt-heavy porter (dark, sweet ale brewed from black malt) - so called because it was the favourite beverage of porters.

Beer raw materials include: malt, wheat malt and burnt malt, black malt, domestic hops and imported hops, hops extract, brewing yeast, beer special disinfectants etc.

But the malt-and-caramel flavoured dark body (actually ruby coloured, rather than black) with a creamy head is worth getting right.
