Before I made my brew today, I sterilized all my equipment.
Then for some stupid reason and no thought, I sterilized or so tried to sterilize my mash tun with a very strong dosage of Sodium Metabisulphite , Not a very smart move on my behalf, as it created unseeable gases which I couldnt smell
But could feel the effects.
It made me feel dizzy,short of breath and gave me a metallic taste in my mouth,
So I quickly opened all windows and doors and also dumped the solution.
Has anyone had this happen to them or know what the gas is?
