Our Mission

To support & connect diverse communities through coffee

We work to make a positive impact through investing ethically in our supply chain, devoting time and resources to develop our local, national, and international coffee community, contributing to local schools, organizations, and causes that help our community, supporting our staff, providing an excellent product and service to our wholesale and retail customers, and providing a hospitable community space in our cafes where people receive excellent service, excellent products, and can connect with their community.

Our Practices

We are committed to sourcing ethically and sustainably grown coffees from around the world. Through building strong relationships with our farmers, we ensure consistent harvest practices, delivering the highest quality throughout the entire supply chain from seed to cup. Many of the lots we source are Organic, Fair Trade, and Rainforest Alliance certified. We also use compostable and recyclable packaging materials in each sector of our business. Small batches are roasted with meticulous care using our Diedrich and Gothot coffee roasters. Roast profiles are perfected for each coffee to develop and highlight the best characteristics from every region.

From house-made milk to refillable canisters, here's how we're brewing a more sustainable future, together.

  • Own Cup Program

    We believe small choices make a big impact — especially when it comes to reducing waste. Our Own Cup Program rewards customers who bring in a reusable cup with $0.25 off every drink, every day.

    In 2024 alone, this simple habit kept over 42,000 disposable cups out of the landfill, reducing an estimated 1,800 lbs of waste. That’s sustainability in action — powered by our community.

    A better way to sip — for you, and the planet. 🌍

  • Canister Program

    Our Canister Refill Program makes it easy to reduce packaging waste while stocking up on your favorite beans. Bring your Airscape canister into any OZO café and we’ll fill it with 1lb of coffee for the price of a 12oz bag.

    In 2024, we tracked more than 10,000 canister refills across our locations — saving an estimated 415 lbs of packaging from ending up in the landfill.

    Better for your brew. Better for the Earth.

  • GaeaStar Clay Cups

    Single-use doesn’t have to mean throwaway. Our partnership with GaeaStar introduced durable, compostable clay cups designed for reuse — or return to the Earth.

    In 2024, we sold 1,770 GaeaStar cups as part of our ongoing effort to reduce single-use waste across our cafés.

    Less landfill, more intentional living. That’s a win in our book.

  • Housemade Milk

    We craft our own cashew-almond milk in-house using just a handful of simple ingredients — no cartons, no additives, and no wasteful transport.

    In 2024, our housemade milk prevented over 3,200 cartons from entering landfills and helped reduce 6,400 lbs of freight. It’s a delicious, sustainable alternative we’re proud to offer.

    Made fresh, made with care — and made to make a difference.
