Beer brewed with the help of AI? Yup, that's now a thing

Four beers have been created, with each recipe altered based on customer feedback received by an algorithm. The system is hidden behind a Facebook Messenger bot, which takes feedback from customers and sends it onto human brewers who change recipes accordingly. This information is then interpreted by the algorithm, which learns from customer feedback to ask better questions in the future. The bot asks questions based on customer preference and flavour and answers are normally marks out of ten, yes or no and multiple choice.
