Thought I'd tack onto this thread as opposed to starting a new one.
I have had a smell/flavour in my last 2 brews that I think is medicinal though my wife tells me it is metallic - as she is always right I will run with metallic.
Only common things from my last 2 brews were water, the fermenter and the first batches on my new keggle. For the 3rd brew yesterday I used filtered water to hopefully rule that out and was also going to use a different fermenter.
However after I cleaned the keggle and let it sit upside down to drain, I tipped it up and caught a whiff of the smell/taste I've been getting in the beer. I stuck my head in but couldn't smell it again. From there, I boiled some water in it and tasted it - the metallic smell & taste were there.
To give a run down of my system, it is a 50L keg with the top cut out with a 3600w stainless steel mounted in a threaded socket that has been welded to the keg. Outlet/inlets are various SS fittings & ball valves connected using thread tape and silicone washers where needed. Wort recirculates via march pump with silicone hoses and cam locks. All equipment purchased from local suppliers and cleaned well prior to first use.
So to get to the point, I would appreciate any advice as to where to go from here?
Thanking all in advance.
Tony
