None of the above are Whiskey as that’s all Irish. Whisky is the Scottish stuff. the Aldi own brand speyside is an award winner and a nice soft intro, other go to favourites are Macallan and Aberlour.
Avoid Islay, Skye or Western Isles Malts as they tend to be very smoky so not as good to start on. The older it is the smoother it gets.
Best to have it in a nice heavy whisky tumbler try a sip, then add a (small) drop of tap water. Don’t put ice in. It just locks all the flavour in and dilutes it at a rate you can’t control
