Sarah Roarty is one of those astonishingly dynamic women whom you are going to be hearing a great deal about. Her first step into the public sphere is the brilliant N17 beer, and she has an oatmeal stout on the way. But it is Ms Roarty's holistic approach to beer making that is particularly noteworthy, as she plans to grow shiitake mushrooms and make dog biscuits from the more than 90% of spent produce left behind in brewing. Watch this woman! And watch this introduction to a singular brewer and beer sommelier.
