Just tried your Sena blend, it tasted smooth with a large Crema on the surface. The beans were roasted beautifully. There was no bitterness unlike some brands of coffee beans that I have used in the past. I recommend that everyone should experience this at least once.
In a word or three, delightfully yummy coffee. Plenty of flavour, not a trace of bitterness. Fresh, delicious and smooth. This is a coffee to look forward to and then savour.
