[1] In 1859, Frederic Robinson took over from George and bought a warehouse to the rear of the inn to expand brewing capacity.

To control the quality of ale sold, Frederic began to purchase public houses.

The Unicorn Brewery still rests on the foundations of the public house on Lower Hillgate in Stockport.

In addition, the company provides casking, kegging and bottling services to other brewers from their site at Bredbury, a short distance from the main Unicorn Brewery.

The Unicorn Brewery is a traditional tower type and was one of the few such buildings still being used in its original capacity until production moved to Bredbury in 2024.
