Coffee Preserve

Single origin green coffee brewed and cultured.. A brew method for single origin coffee, usually reserved for teas and juices.


Green Brewed

Before coffee is roasted, it is grown as a green colored seed within a coffee cherry. Using only single origin green coffee and filtered water, we extract flavor. This green coffee infusion is then fermented by a symbiotic culture of bacteria & yeast. The result is a sparkling, funky and fruity beverage expressing origin in a new way.


This processing technique is an old one which we believe provides a much needed tool of sustainability for the coffee industry all along the supply chain.

Being able to introduce a delicious coffee drink with a positive social and environmental impact is something we are really excited about.

Preserving flavor in single-origin coffees is also another facet to this project that we are looking forward to exploring.


-Caffeine content? About the same as a traditional cup of coffee, 100 mg roughly.

-Sugar content? Relatively low, most is converted by the culture.

-Alcohol: below .5% abv, if sensitive to alcohol, it is generally recommended to avoid.

-How long does it last? It will never go bad in the sense of spoiling, however, to preserve the intended flavor, keep refrigerated up to 90 days.

-What does it taste like? There is some acidity and sweetness with the flavor of the green coffee sitting within that balance. It is grassy & fruity with the particular flavor notes of the single origin coffee being expressed in it’s own unique way.

-How was this figured out? After mixing apple cider vinegar, honey syrup and sparkling water with the green brewed coffee; there was noticed a similar profile to fermented beverages. So we decided to do away with the mixers and culture the green brewed coffee- turns out it’s pretty tasty.

-How can I buy this? Currently this is only available to Olas wholesale partners in NYC on a wait-list basis as our production grows. Otway , Celestine , Rucola , Gem & Abraço currently are pouring by the glass, and Oliver Coffee by the bottle- swing by and enjoy!
