This summer, sandwich experts M&S are launching three new beers brewed using surplus bread from their sandwich factory. Aptly named ‘ Used our Loaf ’ surplus crusts replace some of the malted barley in the brewing process – helping reduce the carbon impact of the beers and reducing food waste.
Brewed by Adnams in Southwold, the new range will comprise three flavours:
- Used Our Loaf Raspberry Fruit Beer (4.5%) 330ml £2.00
- Used Our Loaf Earl Grey Pale Ale (5.0%) 330ml £2.00
- Used Our Loaf Triple English Hop Pale Ale (3.6%) 500ml £2.50
M&S’ popular sandwiches are made by supplier Greencore in Northampton only using the slices and not the crusts of the loaves of bread. The fresh crusts are frozen and then sent to Adnams where they can be used to make the beers.
The method to make malted barley is an energy intense process, therefore by using bread this reduces the carbon footprint; the saving from the three new beers will be 1.2 tonnes of CO2.
Every batch of these three beers will use 700kg of surplus bread, and if they prove popular with customers, the process will be rolled out across more beers, potentially having a significant impact on carbon and waste.
