My suggestion for most folks who want to get into whisky tasting in a bigger way would be to simplify your "log" by first limiting the identifiers to Name of Brand, Age, and any specific other info such as cask strength, Portwood, secondary bottler, etc.. Second, I would simply keep a log of what you drink, and whether you like it or not and a very simple explanation of why---like, very light on the tongue with a soft finish, or dislike, strong, bitter and with a back bite finish. Much beyond that and you will not be able to keep any really useful information. You can always look up where the specific whisky is distilled---speyside, islay, lowland, highland, etc... and other details. But your own overall impression is most important, along with a few small discerning reasons if you are able to do so. If not you will over time develop the ability to do so. In the mean time enjoy. What you want in the end is two things---a more experienced and educated palate, and a memory journal of what you liked and disliked so you can more frequently enjoy those which particularly struck your fancy and you don't repeat your "mistakes" by repeatedly buying something that does not suit your tastes (as if anyone could consider drinking any single malt scotch a mistake).
