India's Food Safety and Standards Authority pulled certain Old Monk and McDowell's expressions from shelves - neutral spirits with flavoring, sold as rum. Here's the backstory, and what counts as "rum" around the world. The latest from my Rum Wonk Newsletter. www.rumwonk.com/p/rum-police...

Came across this today. The remaining Caroni rum offered at auction in 2008. While a substantial amount of rum was for sale, including 5388 casks, several major players had already made purchases, presumably of the best lots. Among them, Angostura, Main Rum, Velier, and likely Bristol.

Today's pickup: Dry Curaçao “Tropical,” which joins the original and Yuzu Late Harvest in Ferrand’s lineup. What makes it tropical? Rather than the grape distillate of the original, it's built on rum from the West Indies Rum Distillery in Barbados. No great surprise there. (1 of 3)

Tasting Sail No. 2, the second limited-edition of Planteray’s Navy-style rum. To my palate, No. 2 dials back the fruitcake spices of No. 1, replacing them with more Demerara and heavy Trinidad notes. All in all, I find the No. 2 closer to the flavors I associate with the RN flavor profile.

While Appleton Estate and 1749 are nearly synonymous, the brand itself only dates to 1944. The brand was registered in the US in 1945, as seen here. The earliest use in Jamaica was 1944. While "Appleton" previously appeared on Wray & Nephew labels, Appleton was a descriptor, not the brand itself.
