I'm surprised that it's really good. Because I had had a number of Daiquiris with Havana Club 3 y.o. and according to the 6:2:1 formula , and I found them OK, but nothing special. And as a rum friend I didn't have a high opinion of Bacardi carta blanca, because consumed neat it has a faint aroma that seemed quite questionable to me. But in this Daiquiri I also notice what Simon Difford described as a savoury mushroom/blue cheese note; it reminds me also of Brie or young Camembert . Interesting!
