Decaf has its place for people with heart conditions. And there is more people buy it than you may think.
I get that, and I'll drink some myself, on rare occasion. I mean as a recreational drink for the masses, it's pretty much as worthwhile as drinking coloured water, but yes it's better than nothing if you have health issues. But then, unless it's the "Swiss water process" I don't see much health in the solvent-based decaffeination process, ugh.
Hey, I'm far from a coffee snob, save to say that I'll draw the line at buying own-brand supermarket instant junk (and DEFINITELY avoid Aldi/Lidl stocked stuff - may as well drink muddy water).
Lavazza instant is very nice, Nescafé is pretty nice too, and Lavazza beans are lush, "Qualita Rossa" are 1Kg/~£12 online, and also Amazon's own "Solimo" beans turned out to be the only ones I had left in my cupboard, recently, so I gave those a second chance, having told myself "any port in a storm" when my Lavazza (and money!) ran out.
I lowered my expectations, and told myself not to be such a picky snob, and my brain fell for it, they're not too bad **if you have no choice**
I'd never CHOOSE Solimo over anything, but they're fine when you tell yourself "it's these or nothing", and I don't plan to waste the 2Kg of beans Amazon told me to keep, gratis, I don't like waste.
