Guy Kawasaki has a fun post with lotsa pictures (How to Change the World: The Art of the Perfect Pint Pour ) detailing his tour of the Guinness Brewery. Perfect St. Patrick’s Day prep work 😎
I missed this tour when I went to Dublin 😦 I did see the brewery from the tour bus. It is huge. If I remember correctly almost all of the production is consumed locally!
Kawasaki says — This is where the real production happens. This facility brews roughly three million pints per day.
