This solid-value Riesling from the Pfalz is so good... and then so not. It is, at first, just as you might expect, a straightforward, uncomplicated expression that is also very tasty, off-dry but only just, with soft peach and pineapple accented with lime and slate. There isn't enough acidity, nor enough minerality, but the ripe tropical and orchard fruit is nice. But with time, things really fall apart. The fruit just seems to crumble, and what's left is an almost undrinkable mess of stale nuts, bitterness, and an odd funk. This was an 87-88, then a 79-80. Drink it right away.
