Port Hills Mild Ale

The grist for this beer came from my stuff-up at a home-brew store where I work. I was measuring grain for a customer and mis-measured. I couldn’t sell the grain to the customer so I was given the grain to brew with. I have no idea what the original plans for the grain were, but I decided to brew a mild ale – a style I’ve brewed before and really enjoy. It benefits from not being served too cold. Cellar temps are perfect or all the malt flavour disappears.

The name comes from the big fires in Christchurch in Feb 2017.  I love the Port Hills and it’s hard to think of them all dark and roasty like this beer. I sent some down to my mate, who had to evacuate his house in Kennedy’s Bush. I hope they went down OK.
