One of the most frequently wasted foodstuffs is bread. As a relatively cheap product with a short shelf life, bread is chucked out at an astonishing rate, as supermarket surplus as well as in the home.
The startup Toast Ale have an unusual and appealing idea of how to combat this problem – by brewing beer. It’s a relatively simple process, so much so that the first batch of Toast Ale was arranged in just 10 days by Founder Tristram Stuart and his team. The company start by collecting surplus bread from delis, bakeries and sandwich makers. It’s then incorporated into the brewing process with malted barley, hops, yeast and water. It doesn’t take any special technology or space-age methods, but this simple switch can replace around a third of the malted barley used for beer.
