Toast Brewing has partnered with Jason's Sourdough to launch a limited-edition hazy IPA that incorporates over half a tonne of surplus sourdough.

This innovative collaboration not only highlights the growing trend of sustainability in brewing but also reflects a commitment to social responsibility within the industry.

The 5.5% hazy IPA, available in more than 200 Waitrose stores across the UK, is crafted with a unique blend of ingredients, replacing a portion of malted barley with surplus loaves from Jason's Sourdough.

The result is a beer characterised by vibrant citrus and peach aromas, balanced bitterness and a smooth finish – aptly described as reminiscent of 'great marmalade on toast'.

This partnership is a strategic response to the pressing issue of food waste, a challenge that has garnered increased attention in the food and beverage industry.

By uses surplus bread that would otherwise be discarded, Toast Brewing and Jason's Sourdough are not only creating a distinctive product but also significantly lowering the environmental impact of their operations.

This approach reduces the demand for land- and resource-intensive crops, thereby cutting carbon emissions associated with traditional brewing processes.

Jason Geary, Master Baker at Jason's Sourdough, expressed enthusiasm about the collaboration: “We’re delighted to partner with Toast Brewing on this limited edition beer. This collaboration allows us to give any surplus sourdough a new lease of life, turning it into something delicious."

he continued: "By combining our expertise in traditional sourdough with Toast’s innovative brewing, we’ve created a beer that celebrates craftsmanship while tackling food waste”.

Founded just five years ago, Jason's Sourdough has quickly ascended to become the UK's leading sourdough brand, known for its commitment to quality and sustainability.

Baked using traditional methods and high-quality ingredients, their bread is free from added yeast, preservatives and unnecessary additives. The company also prioritises renewable energy in its bakeries, further enhancing its sustainability credentials.

Louisa Ziane, co-founder of Toast Brewing, emphasised the importance of purposeful collaboration in their mission: “We’re incredibly proud to team up with Jason’s Sourdough for this beer, to put their delicious surplus to good use and tackle food waste in a creative way together”.

The launch of the Toast Brewing x Jason’s Sourdough IPA has been met with enthusiasm from retailers and consumers alike.

Jourdan Gabbini, Beer Buyer at Waitrose, added: “This clever collaboration is one we're truly excited about. Jason's Sourdough is a brand that is already loved by so many Waitrose customers, and with such a strong purpose behind the product, we're confident this beer is going to prove very popular.”
