Guinness is one of the most recognised drinks on the planet - but there is much we don't know.
Well not for much longer, as the famous brewery is opening the doors of its experimental Dublin brewery to the public.
The Open Gate Brewery at St James's Gate in Dublin is where the brewers are given license to explore new recipes, reinterpret old ones and experiment freely to bring new beers to life.
Now, for the first time in history, the brewers will welcome the public into the brewery.
As well as pouring the famous stout, brewers will be sharing early, small batch versions of their experimental beers to try.
A selection of other new beers from around the world, which have not been available to date in Ireland, will also be available to visitors.
Speaking about the opening, Guinness brewer Peter Simpson said: "We feel extremely lucky to work in The Open Gate Brewery because my fellow brewers and I are given free rein to regularly explore and create new beers in small batches".
"There is huge interest in beer nowadays so it's exciting to open the doors to the public, give people a look inside our world, and of course share some batches of experimental beers that we are working on".
