26 Mar 2019 --- Lost Sheep Coffee is launching its single origin coffee in plant-based capsules that are certified biodegradable, compostable and airtight for freshness. Until recently, the shelf-life of compostable capsules was short as the coffee inside would go stale. “Without plastic or glue, it is incredibly difficult to create an airtight seal over the product. After extensive research and development our new capsules achieve a level of oxygen impermeability which enables Lost Sheep Coffee to guarantee a minimum shelf life of 12 months,” says Stuart Wilson, Founder of Lost Sheep Coffee.
