Rémy Cointreau has joined French peer Pernod Ricard in buying into sustainable logistics platform Ecospirits, despite also announcing a sizable savings drive. The brand owner, which booked a six-month sales slide of almost 16% last month, has built on its existing relationship with Ecospirits. The pair, which have been working together for two years, have arrangements for several spirits brands, including Cointreau, to use Ecospirits' reusable container crates in the on-premise channel. This week, Rémy Cointreau's RC Ventures venture capital unit, acquired an unspecified stake in Ecospirits. The purchase, the first for the newly-created division, sees the group join Pernod Ricard as an investor. Financial details were not disclosed.
