Why does the U.K. list caffeine under "flavourings" when it doesn t affect taste?

I understand it has a SLIGHT bitter taste, but the 50mg or so in soda doesn t really affect taste whatsoever, so why is it listed under flavorings? Is it a social thing (aka people don t want to admit it s an added drug?)

In the U.S. it s not listed as flavouring.

It seems sort of deceptive to me.

Yes, caffeine is clearly an addictive flavorless flavouring that we add.
