I've had the Select Reserve when out for dinner and it was quite different to me from regular Jamesons. There's quite a sherry cask influence to this one. Maybe give the bottle some time to breathe and try a teaspoon of water and covering your glass (ideally use a wine tasting glass if you can) and leave it for 20 minutes. I bought Jameson Caskmates (stout) and didn't find much of a difference, it took me till I was almost finished it to find the difference and realize I didn't actually like it.
There's plenty of good interesting whisky in the 300-450 range.
- Tullamore DEW 12 - Similar to the Jameson's Select Reserve but imo better and better than most Scotches in the price range usually priced at R389~ at Makro.
- Most bourbons (Bulleit is good but liquor city has Elijah Craig which gets good mentions)
- Private Barrel no 68. I can't speak for their Irish but this one is a spicy Speyside and at the end of my bottle I really found myself wanting it again.
- Loch lomond single grain
- Bells Special Reserve (See review a few pages back, Slightly peated)
- Johnnie Walker Black/Double black - Actually nice whisky considering how mass-produced it is. (Slightly peated)
- Dewars 15 - Better than many higher priced Scotches imo.
- Three ships 5/Bourbon cask and Bains are all great for the price.
- Liquor city stocks Glen Moray and I love the Peated one but heard good things about the Chardonnay cask at least.
- Glenfiddich/Glenlivet 12 are both fine drams
This list isn't exhaustive but it all really depends on whether you want something a bit more interesting or something easy to drink. It's important to enjoy drinking whisky, that's why people recommend better whisky because it generally leads to a better experience.
Also ideally try to try before you buy unless you really trust a review or recommendation! It's worth knowing what you're getting and I realize that's not always possible but some bars do have decent selections. Yes this is pricey but better than regretting a whole bottle. But exploring whisky is always a gamble and sometimes a bottle you initially dislike becomes something more as time passes and sometimes something you think is a sure win isn't. For me finding the gems is the greatest prize and experience.
