Ah well, you are right, I don't buy my coffee from the right roasters - I doubt Waitrose roast any themselves.
The trouble is I've never really taken the time to hejjercate myself about coffee, it seems far more complicated than wine but the potential rewards - knowing what coffee you are likely to enjoy - might be as useful, if not more so. I used to think it was quite similar to wine, that is once you take away the wankeybollocks with wine. Once you know the grape and the style, you have some idea what it will taste like, especially when it is more traditional in its vinification. The equivalent in coffee terms in my mind was bean variety and roast. So, all I needed to know was high roast arabica, and that was it. Top up on my Cafe Grand Mere Degustation or Carte Noir while in France, I was sorted. Add to that Waitrose own brand espresso and my needs were satisfied. Life was simple.
Trouble was, sometime during my extended absence from coffee drinking all these new coffees appeared on the shelves, along with bean to cup machines etc. I've been working my way through all sorts of different options, with limited success, blends and roast are clearly angled at a wide range of tastes (no shit, sherlock) and also drinking preferences (coffee maker, milk, sugar). The simple correlation between bean, roast style and enjoyment seems to be broken by the levels of sophistication and choice. Along with the ubiquity of coffee shops, black no sugar is no longer as mainstream as it used to be and many coffees are clearly blended with that in mind. The Cuban coffee was unusual in that the flavour has grown on me. It still tastes "thinner" than I prefer to start with, but I enjoy the flavour and the final effect is a satisfying cup.
I'll give that Jampit a try, and I see they also do French Breakfast blend which will likely be up my street.
