Has anyone tried Boplaas whisky? They are a local winery/distillery and make some cracking single grain whisky (from 100% maize). Before you dismiss it out of hand for being grain whisky, let me say that the kicker with this distillery is the casks that they use for finishing. They produce everything from port wines, brandy, gin to whisky etc., so they can use their own casks for finishing. This means that they don't need to get casks seasoned with a lower grade or younger wine/liquor from some other place. They can use casks from their stock that actually matured award-winning port or brandy, for example, to further mature and finish their whisky. The only exception to this is a rum cask finish that they make. For that one, they exchanged some barrels of theirs with ones from a rum distillery somewhere, so those may still be some good legit ex-rum barrels.
I bought two of their bottles, the cheapest one, a brandy cask finish (no age stated, but it would be 3 years at least, maybe even 3-5), and the most expensive one, the 8 year old single cask bottling from a tawny port cask.
The brandy one is pretty delicious. I also tried some of their 15 year old brandy. It's pretty good, but it's a bit one dimensional and very sweet. The brandy finished whisky, on the other hand, is just much nicer. Still a lot like the brandy but better. The single cask is just excellent. You even forget that you are drinking grain whisky with that one because the cask influence and strength is just so intense and delicious. I also tasted some of their very old ruby port, and this is a bit reminiscent of that. However, I sadly could not taste their actual tawny port as they were all out, so I don't have a direct comparison for the influence that the finishing might have had like with the brandy. This 8 year old also has a little brother, a 6 year old, also finished in tawny port casks. It's bottled at a regular 43% ABV and not from a single cask (though everything from them will be small batch). I didn't try the 6, but it might also still be good. All their whiskies contain no artificial colouring whatsoever and have not been chill-filtered at all. Not saying this stuff is going to be for everyone. I'm just putting it out there in case someone is reading who has not heard of or thought to try this yet and who might be interested.
It's not produced in large quantities and widely available like say, Three Ships/Bains. They are more like a craft distillery really. If you are ever anywhere near Oudtshoorn, then I would strongly recommend you visit them in Calitzdorp, about 50km to the West. There is also a Boplaas tasting room/shop not far away from Hartenbos right next to Klein Brak at Klipheuwel. You can also check on boplaas.co.za if there is a distributor near you or order from the site directly.
