Our green coffee beans come from several countries in the “Coffee Belt”, the equatorial strip between the Tropic of Cancer and the Tropic of Capricorn. We roast coffees grown in Colombia, Indonesia and Peru, among others.

All batches of green coffee are analyzed by Café William's quality team on arrival to ensure that the product meets our requirements. Since green coffee is a dry ingredient, coffee batches are not prone to bacterial growth. However, Café William's quality team randomly tests batches to ensure that no molds or mycotoxins are present in our products. Moreover, state-of-the-art equipment has been installed in our production line to remove any foreign matter that may have entered the green coffee during harvesting.

Many of our coffees are available in ground or whole bean format. Using the drop-down menu on the product page, you can choose one or the other.

It is possible to identify the main flavor profile of the majority of our products via the color of our coffee bags:

- Yellow bags are light-roasted coffees
- Green bags are medium-roasted coffees
- Blue bags are dark-roasted coffees
- Red bags are ideal for espresso machines
- Purple bags are decaffeinated

Note that some Costco products and special editions have a different color. For more details on their taste profile, please refer to the description on the packaging or on the product page of our website.

Café William is proud to use only beans naturally decaffeinated with water, using a process commonly known as “Mountain Water”. No chemicals or solvents are used in the decaffeination process.

Our dark roasted coffees packaged in blue bags have a slightly oily surface. In addition, our Espresso Barista and Sumatra coffees available at Costco are more oily due to their darker roast. We therefore do not recommend using these coffees with automatic machines, unless you alternate with a less oily coffee and maintain your machine more frequently.

Our coffees packed in the red bags are perfect for making delicious espresso-based coffees. These coffees are a skilfully calculated blend of Arabica beans from different origins and a small percentage of premium Robusta, resulting in a beautiful crema. Light to medium roast, our espressos have no surface oils, which helps protect your grinder.

Since the Espresso Barista and Sumatra available at Costco have more surface oil given their darker roast, we don't recommend them for use with an automatic machine, unless you alternate with a less oily coffee and perform more frequent maintenance on your machine.

Since our Vision coffee has a lighter roast, it's normal for the grind required to be finer. The paler the roast color, the finer the grind required.

The best way to keep coffee beans fresh is to store them in an airtight, opaque container, out of the sun, in a cool, dry place at room temperature. Café William bags feature a one-way freshness valve and a tightly sealed zipper to keep beans fresh longer.

We don't recommend storing your coffee beans in the fridge or freezer, as coffee is a sensitive food and will absorb odors from the fridge or freezer.

You can buy our coffees on our website, in Costco warehouses in Quebec and Eastern Canada, and on costco.ca. In grocery stores, you can buy many of our coffees at Metro, IGA, Super C and Provigo, among others. Locate the store nearest you in the Store Locator.
