i made 23L of youngs Scottish heavy two/three months ago. i open a bottle and pour in to a pint glass the first two mouthfuls are great its a good heavy then the third is yuck and the rest to. it's a powder taste is it just me or is there something going on with it.has anyone heard of this before it's very strange i think the only way to have a pint is to down in one lol.or is it all in the mind.
