Today, supermarkets like Coles, Woolworths and Aldi are stocked with pre-packaged whole bean coffee and pre-ground coffee. the biggest problem here is the freshness, which is especially important to the flavour and crema of your coffee. You are forgoing fresh roasted coffee (roasted on the day you order) for pre-packaged coffee that needs to be manufactured, packaged, warehoused, transported, stocked and then eventually making its way into your trolley, your coffee can be anywhere from 3 months to 12 months old, and that's just not a good idea today, especially when you pay a similar price for coffee from the supermarket compared to fresh roasted coffee delivered to you door (with free delivery)!
Give it a try, and you'll really appreciate the difference to your daily coffee.
