Email Follow on: Gil Lempert-Schwarz More Columns/Blogs Wine: KM501 Rhein Riesling. Grape: riesling Region: Rheingau, Germany Vintage: 2011 Price: $8.99 In the glass: KM501 riesling wine is a faint citrine-yellow color with a clear, bright, light-greenish tinged core going out into a fine glass-clear meniscus (rim definition) with light to medium viscosity. On the nose: There are fresh bright white fruit characteristics with pomelo pulp, white grape juice, ripe apples or applesauce, crushed apricots, brewer's yeast, citrus rind and chalky minerals. On the palate: The wine is light and refreshing and incredibly soft, with cooked pears, apricots, red apples, no discernible alcohol or wood, just pure sweetish white fruit meat with crushed white currants and applesauce through the midpalate. The finish is light and tasty with hints of minerality and just a lingering touch of bright acidity and apples.
