> The inescapable conclusion is, the supposed differences between white and red wine are imaginary. The problem is that white/red is a very large grouping of wine. There are very light reds with low tannins that could be hard to tell particularly if served at room temp. There are some robust white wines that fall into this same overlap. In general, red vs. white is normally pretty easy assuming typical red and white wine. Within these large groupings of white/red there are also other trick wines. Reds where the grape seems like a different grape due the region or wine process. Dry Rieslings are often tricky because most people assume sweet. So non-expert tasters being tricked by trick wines is not really an interesting find. The problem for most people with wine tasting is it's hard to do it in a way to learn. It's not enough to buy a bottle once/week. In one trip to France, I tasted 100+ wines over a 2 week period. Only when you have wines side by side, day after day do you really start to learn. Sommeliers taste 1000s of wines over many years, taking notes and actively working to learn the flavors.
