The NV Amontillado S. Roberto Bota Única 1/2 is a wine of incredible finesse and balance, elegant and surprisingly light for such an old wine. It is less concentrated than the other barrel (2/2) and has a lot more elegance. It's unusual to find such old wines with this balance, as extreme evaporation often means unbalance, but there's none of that in this wine that has clarity, purity and finesse to make it dangerously easy to drink.
