If you are starting a coffee business it doesn't make sense to me to buy beans in quantity of a hobby roaster. Even if you are only selling 25 lbs. of peans per week, you will go through 1000 lbs. (9+ bags) in ten months.
This might be a bit tough to understand at present, but for getting to know each bean and consistency of blend, buying in larger quantities is much better. And then you have the price factor.
If you buy small sample lots of green beans and roast a bunch of batches to learn the beans and let potential wholesale customers taste your product you will have to be reordering beans before you really fill any orders. If you then order full bags from another supplier, the beans you will use to fill the orders won't even necessarily taste like the samples you presented a few days/weeks back.
We've been in this business less than a year and I'm already ordering multiple bags of certain beans that we really like, as they tend to go fast and we want to maintain consistent quality.
I'm not sure about food sanitation laws in my area but I figured I probably don't need to worry to much about that until I grow into an actually facility other than my house. I would just rather have to cash to start this business instead of going into debt without having any customer base yet. I plan on starting selling locally at farmers markets, local market places, small restaurants, small businesses, family and friends initially with the smaller roaster and then see where things go from there. My goal is to be financially sufficient with this business alone in the next 3-4 years. There is hardly any independent roasters in my area and we have a huge population and one of the largest tourism destinations in the states. I know of one other small batch roaster in my immediate area and he is basically where I want to be right now with a 6lb roaster doing it out of his garage. I hope that kind of clears up my vision and goals a little for you. Thoughts and criticism welcomed.
