I'm wondering about how best to improve the coffee I drink regularly. Preferably without either creating huge amounts more work for myself or spending a great deal of money. The latter, combined with the fact that I don't drink milk in coffee, means that I have already ruled out upgrading the moka pot to an espresso machine: it's beyond the budget I'm prepared to spend at the moment, although I don't wish to rule it out for the foreseeable future, which means it would be good if any upgrades I make now were compatible with such a move at a later date. I currently mostly use filtered Berlin tap-water and pre-ground dark-roast espresso from cafe liberdad, a German collective who import coffee from co-operatives in Chiapas and Costa Rica. This makes an acceptable but not exceptionally good drink. For various reasons, I'll probably be sticking with the same suppliers: they also offer roast whole beans (which I have bought on occasion) and raw coffee (which I have not yet bought). I have access to a hand-powered burr-grinder, which I have used on the occasions when I have bought whole beans. The grounds are noticeably coarser (or rather: not so uniformly fine) than the pre-ground stuff. The resulting coffee was slightly but not a huge amount better than than that from the pre-ground beans. It is hard to be certain, but I think that the coffee made shortly after the packet was opened was better than that at the end of the packet (which I stored in an airtight tin). Are the most substantial improvements to the end-product likely to result from home-roasting, getting a better grinder, storing the beans differently, something else I've not thought of, or some combination of the above? I'm assuming that the biggest advantage of home-roasting comes from the freshness with which I will then have access to the roast beans, rather than the quality of the roast per se. And have no idea whether this benefit can be achieved through other methods, or how much a difference a grinder can make, etc.: all advice gratefully appreciated!
