The European Union recognizes that enterprises can have a negative impact on society and the environment. It recommends preventing and counteracting those undesirable effects as part of corporate social responsibility (CSR) … conducted voluntarily.
On the other hand the Mauritian Ministry of Finance imposed a mandatory 2% social and environmental development contribution on all registered (and profitable) companies. Funded programs must be accredited by the Mauritius Revenue Authority (MRA) at the time of submitting their Tax Returns.
You won't believe it - everyone is satisfied: local communities, NGOs, state authorities and even the companies themselves. It's true that the latter don't really have a choice because open objection would be negatively perceived and furthermore would even so affect their reputation. Moreover, in the public sphere it isn't so sexy anymore to rely on Friedman's 'greed is good' meaning profit maximization is the one and only goal of business. As a sweetener for the inconsolable - investments in CSR translate into customer satisfaction and reduce employee fluctuation, which in the long term provides improved financial results of the company.
Grays Distillery is part of the Terra Mauricia Ltd conglomerate. I admire their approach to reporting; materials are synthetic, transparent and aesthetic (btw you may take a look at the financed CSR projects). The same applies to brand communication; successfully rebranded (2018) in cooperation with WDK Solutions. Black backgrounds were abandoned in favor of tropical-exotic colors; the endemic plant Latanier Bleu Palm leaf was chosen on the logo. The brand was founded in 2003 but till fairly recently uses the claim '5 Star Rum Single Estate Brand' and then 'from field to glass' meaning…
...all processes are handled by the Mauritians themselves. They own plantations where they grow 12 sugarcane varieties on 16k hectares. The fermentation lasts 30-hour basing on their own yeast strain. The wash goes through multiple column distillation; until 94% abv is obtained. The purity of the distillate is checked by gas chromatography. The blend is aged for one to three years in used French Limousin Oak barrels, some of them in ex-cognac barrels. However, 30% of the distillate ends up in new barrels to gain more complex aromas. The final result is rum and water; no sugar, no ageing agents, no colourant or other additives.
New Grove is completely transparent about the production process. Don't ask me why some distributors and even reviewers provide the incorrect aging period (1-15 years). The consumer has the right to know exactly. The reviewer appreciates the first-hand source. Both should praise the manufacturer for the clarity.
