Origins at the Granville Island Market might let you in on some...
The is also a roaster down on West Broadway a few blocks above Alma in the West end... Yoka's Roaster I think - they might be open to selling you some.
Cairo Coffee Victoria sells green coffee as well.
Thank you both for your suggestions re. sources for green coffee beans in the Vancouver area. Each of those you mentioned - GreenCoffee.ca (Delta), Origins Coffee (Granville Island) and Yoka's (West Broadway) - has a variety of green beans available. I have purchased some and am in the process of testing them.
I also bought some roasted Espresso beans at The Elysian Room, after reading glowing comments on this website about them. I like them very much.
I've got no suggestions about where to get beans in BC. I live in Ontario, and locally, there is only 1 roaster that I know I can buy green beans from. Trouble is, they want to charge me roasted bean prices for the same weight of green. Their roasted prices are reasonale, but charging the same for green is definitely not appealing.
I've tried greenbeanery.ca, and find some of their pricing strangely expensive. I am new to the roasting thing, and so far, have not found better bang for my buck than with Sweet Maria's. With the shipping, it's not always the cheapest, but prices are comparable, or even better at times compared to greenbeanery.ca and other Cnaadian mail-order sources (shipping taken into account) and the quality seems to be there...
