Violette you are of course entitled to your opinion of what you think is good coffee.
Coming from Canada I have to say I could never drink Tim Horton's (I tried I really did!), I consider it gut rot, maybe I'm allergic to the additive? There's a Canadian I met recently in Helsinki who's missing it. Starbucks I basically consider bath water for the amount of quality coffee you get in it compared to the amount of milk. You basically need a double shot of the coffee to get any taste then you realise the coffee isn't good to begin with. I feel the same about Second Cup too. IMO
I just came from living in Australia for the last six years and the sad truth is that there are doughnut stores and other small coffee stands in Australia that put Starbucks to shame, which is why they're basically out of business in Australia.
I'm not sure if I've had Kulta Katrina here yet, I may have had it in Australia (there was a Finnish bakery we used to go to). Your description is interesting to say the least... I do enjoy the Paulig Parisien if I were to choose a Finnish store brand of coffee.
The Finnish people I've talked to so far have basically told me they drink what they do because of price and it's 'good enough'. Again going with my statement that Finns drink it to just drink it.
Maybe I'm too picky about my coffee...
Then again, I rather enjoy what I drink rather than just drink.
