A delicious and rewarding hobby is brewing beer at home. It is also a complex and time-consuming hobby. If your beer is going to come out right you will need the right amount of hops, barley, yeast, and water. They must be combined and heated at very specific times and temperatures. Homebrewers taking on a new batch of golden brew must dedicate an entire day to its creation — not including bottling. But a handy new robot, developed in Northern Ireland, is putting an end to all that lost time.
