Weinfest der Zeller Schwarze Katz ★ 4.2
Held on the last weekend of June around Zell's market square, this festival traditionally opens the Mosel's wine-festival season with a wine-queen crowning.
Tip: Try the namesake Zeller Schwarze Katz Riesling at its source; this is the first major Mosel fest each summer and less crowded than September's.
