The good news: The boss invited you to dinner. The bad news: You should probably bring a host gift. Before you choke and grab that jug of white zin, check out the expert recs for excellent wine under $20.
Nik Weis is a modern winemaker utilizing traditional German methods. His Rieslings are stylish and elegant, but approachable. This entry-level bottling is in the Kabinett or "dry" style, but don't be fooled: Strong notes of lemon peel and green apple balanced with fine undertones, all brought together by a nice acidity that lends to a fresh mouthfeel.
Don't be afraid to offer to pair this wine with buttery or spicy dishes - it can handle both.
Tasting Cheat Sheet: Bright lemon zest, green apple and grapefruit.
