There are many places you can buy coffee, from single packets for home use or in bulk for your busy coffee shop. Prices do vary due to many reasons; quality included.
We recommend that you buy from well sourced coffee purchased at fairtrade prices from rosters that have good traceability to the farms that the coffee beans are grown on.
We recommended spending what you can afford until you are happy with the quality of coffee drink that are being made. A good relationship with your coffee supplier is important as you know exactly who you are buying off of and can request help and advice with how to get the most out of the coffee you are brewing, drinking and selling.
