where can we get the original iron bru with sugar not that artificial sweetener stuff? Just isn't the same - not buying the new stuff anymore.

The Irn-Bru we sell is made to the original formula i.e. Sugar. It is specifically produced for the US market to comply with FDA regulations and US labeling format.

I heard that they changed Irn Bru. Is this the old stuff or the new one with less sugar?

This is the original recipe. Irn-Bru for the US market (and Canada) is made separately to comply with FDA permitted coloring additives. Also the cans are specifically printed for the US.

Asking in 2021, is this the original recipe or does it now contain aspartane?

This does contain aspartame, but it has for well over 20 years. When the sugar tax was implemented how long ago, they switched to a recipe of part sugar/corn syrup part aspartame to save money and it has been that way ever since. They haven't made it with all sugar/corn syrup since then.
