The oldest and most concentrated sweet wine from Alvear is the NV Pedro Ximénez Solera 1830, a wine that cannot change despite this new bottling from January 2017, as it's so old, concentrated and sweet (480 grams of sugar per liter) that we wouldn't feel its evolution over our lifetime. I've tasted and described this wine before and it's as good, old and powerful as I remember it. The notes I mentioned before, noble woods, espresso coffee, vanilla and coconut are still there and so is the complex, velvety and fine palate, with a luscious and never-ending finish. Unfortunately what is changing with this wine is availability and price. 318 half bottles were produced. The price provided is for a half bottle.
