I remember buying the Oloroso version of this some time ago. Still remember the conversation with the sales guy: Me: What's Nadurra? Sales: means "all natural" M: oh, so its organically made? S: No, just natural M: like locally sourced only ? S: no, just no color or chill filtration, and without water dilution M in other words, Cask strength, NCF, and no chill filtration? S: yes ..so all natural Not sure why that necessitated the creation of Nadurra as all natural, but whatever...still a good whisky. This one is the peated version. Personally, didn't think it was as good as the Oloroso, but still a mighty good dram. Given the high ABV, surprisingly smooth. Thanks to Paul for this round's sample!
