An Essex milkshake business is celebrating booming sales.

Shaken Udder, which celebrates its tenth anniversary this year and recently launched a new Shaken Udder Kids range, enjoyed its best year for sales growth with some accounts growing by 62%.

The firm, based at Wicks Manor Farm, Tolleshunt Major, near Maldon, is run by husband-and-wife team Jodie Farran and Andrew “Howie” Howie.

“It is great to hit this milestone and still be here going so strong and 2014 was our best year to date,” said Jodie.

“Last year was another real learning curve for us; we’d just launched Shaken Udder Kids which is a whole new market and gained new listings with those products, and we also ran our largest ever on-pack promotion.

“It seems these activities have had a strong impact on our year-end results so it’s great to know we are doing things right.”

The couple, who met at agricultural university, got inspired to start making milkshakes while at the V Festival.

They came up with a brand name, and produced 100 different flavours which they decided to sell from a stall on the festival circuit, starting in 2004.

“We kind of had a vision of a funky cow stand,” said Jodie.

Building the business since then has been “massively challenging” but “rewarding”, she said. The couple have since refined the offering to a more manageable 35 to 40 flavours.

The company now supplies Waitrose, Sainsbury’s and Tesco, as well as the East of England Co-op and the Chelmsford Co-op group. Production was outsourced and moved to Somerset, where many dairy farms are based.
