In foreign countries, some people have studied the conversion of urine into drinking water. Some people have studied the use of rainwater for winemaking. Recently, there have been studies to make beer from bread that cannot be sold. The raw materials for beer brewing are numerous, and Xiaobian has to admire the brains of the great gods. It may be too fast to make the equipment too fast. Who knows that the beer that will be brewed in the future is done. In the UK, some people think that there are too many breads to be wasted every day. I decided to work with local bakeries, restaurants and other suppliers to make bread into malt. TristramStuart has been working to reduce wasted food. He read the story of a Belgian brewery, where they collect bread from the nearby supermarkets and make beer Babylone. A report by the non-profit organization WRAP shows that in the UK, 24 million pieces of bread are wasted enough to help 26 million malnourished people, many of which can be avoided, and TristramStuart is doing exactly that. In fact, some people used to make old bread in the two rivers, Stuart said: "The original purpose of making beer is to preserve the heat in the grain, otherwise it will be wasted." Stuart created ToastAle, who consulted the British brewery about the brewing process and recipes, and eventually worked with London-based brewery Hackney Brewery to use a piece of bread in each 330 ml of beer. All the collected bread is sliced, dried, crushed, and then the bread is crushed to replace a portion of the malt, and the subsequent process is similar to making ordinary malt.
