I swear by ground coffee but beyond that, I'm not too fussy. Sainsbury's own brand Viennese grounds are my usual go-to coffee because the flavour has some 'oomph' to it without being overbearing. On some occasions when I feel like treating myself to something a bit more fancy, then I really like trying different CafeDirect grounds (next on my list is the Kilimanjaro coffee - I haven't had that one yet!) I used to really enjoy Boaters instant coffee as well (especially the hazenut, amaretto and vanilla varieties) but that seems to have disappeared; not sure if it's just that shops in my town don't sell it anymore or if the company has gone belly up or what!
