    It's claimed Robusta beans have up to twice the caffeine of Arabica.
    As far as Robusta in instant goes, could well be the case, does it really matter.

      My understanding is that robusta has between 2.5% and 3% caffeine, compared to 1.2%-1.8% in arabica, so yes approximately twice as much in general terms but some robusta beans could have three times as much as some arabica beans. (and some only about 38% extra).

      I'd be surprised if there are no instant coffees with arabica, but they'd be few and far between.
