Northern Brewer
Landlord.
The first AG brwew on the new brewery had a metallic tang. 80L of 1065 ale down the drain, I cleaned the whole brewery down and tried again, with a smaller brew length and 1050 OG, It got worse, distinct copper taste, another 60L down the pan. Just goes to show its not how big and shiny it is, it's what you do with it that counts
So I spent 4 hours cleaning everything with Five star PBW oxygen based cleaner and 80 degree water from the HLT throught the plate heat exchanger, HERMS heat exchanger then into mash tun and back using both pumps. Then emptied this into the boiler throught the tap with the hop filter in place and washed the lot in 80 degree water recirculated and flushed with cold. The resultant water was green, not sure if that is the action of the hot cleaner on copper or it removed existing salts, I hope its the latter and my problem has gone, however I think its cause may by electrolytic action of my bore hole water that has a high iron content, so I have gone back to using a seasonal spring I have, its not plumbed into the brewery so means I have to cart 3 or 4 25L bottles down to the brewery but if it stops it then I don't care.
Here's the resultant washing water, not sure the green tint can be seen on the picture?
Here's the spring I'm now using, not out of the trough though which is full of blanket weed.
Here's the brewery doing what it should with the recirc going but with cleaner not wort
And after thinking about making a steam canopy I think this does the trick and I get some condense back in the brew so less loss due to evaporation, the fan is outside the brewery in the barn.
Here's may latest brew recipe - a bit of an experiment with Citra, never used it before.
Ignore the brew length and OG, it came out at about 67 litres and 1042, I was aiming for 1040 - I'll set up Brewsmith properly when I get time
