Ester marques

It's not possible. The four distilleries on Barbados have problems to agree to one GI. There is no international institution that could establish such labeling standard. Each county has it's own regulations. And they are not obliged to provide a mark at all. It's also the problem with Demerara. They have at least 10 marks and they don't write them on the lable. Diamond could be a MDX or MDXC or maybe an Enmore in some cases. You don't know until you open the bottle. It's a big mess.

Poor information is a general problem when it comes to rum because it is so diversified and some producers aren’t interested enough to declare the content cause it would reveal their way of trying to deceive us. What can we as consumers do? Probably nothing except boycott this kind of producers who don’t live up to our expectations, but it’s likely fruitless. Something like that must be much wider to have a chance of being successful, we can now see that some producers adapt the rules around rum that EU has established which I think is good. Another possibility could be if organizers of rum festivals, rum cruises and similar events did not invite the producers who don’t meet any form of minimum requirements.

I realize that it isn't really possible to require it across so many different countries and expressions of rum, but I'm surprised more distilleries/bottlers don't do it voluntarily. Maybe someday.

I reckon the only way it could come to be and consensus happens, is if a body like the EU implement labelling regulations that then might just be accepted world wide. While of course different labels could be made for different markets, the hassle, cost and potential issues with stock control might lead to the adoption of just the one label. But of course, that might just be wishful thinking!!
