As Mondelez rolls out its Nespresso-compatible pods to UK supermarkets, other suppliers have started ramping up their coffee capsule activity.

Fairtrade specialist Cafédirect started rolling out pods to 200 Waitrose stores this week, while Marley Coffee - founded by Rohan Marley, son of musician Bob Marley - announced it was moving into capsules.

The Cafédirect Nespresso-compatible range initially comprises four lines (rsp: £2.99/10 pods), but is due to expand later this year.

“We wanted to give consumers an ethical option in this growing market,” said Cafédirect commercial director Nicola Pearson.

Marley Coffee offered attendees at organic trade fair Biofach in Germany this week a “sneak peek” of its Nespresso-compatible range. It also revealed its new RealCup capsules, which are compatible with the K-Cup system - an alternative to Nestlé’s Nespresso system - and feature a filter inside each capsule.

Meanwhile, British Nespresso-compatible business Cafépod is to expand its line-up with two single-origin products - a Fairtrade Colombian Huila and Sumatran Lake Tawar - and a longer-serve Lungo. Waitrose recently extended its distribution of Cafépod to 290 stores and the brand this week rolled into 600 Tescos.

Retailers are showing increased interest in pods. Mondelez this week launched Carte Noire Nespresso-compatible pods into UK supermarkets. Official Nespresso pods can only bought from Nespresso stores or its website.
