The research brewery has inspired such beers as Guinness Blonde American Lager, Nitro IPA, and West Indies Porter. At the moment, the brewery is playing with an imperial dunkel weisse (a strong, dark German-style wheat beer), an amber Vienna-style lager, and a Belgian-influenced Antwerpen Stout.
In the early twentieth century, Guinness became the largest brewer in the world, exporting the Irish style to many countries. Although no longer the largest brewer in the world, it remains the largest brewer of stout. In 2014, Guinness sales amounted to 19% of all beer sales in Ireland.
