A new and distinct aroma variety of hop plant, Humulus lupulus L., named ‘Delta’ is characterized by its good cone yield, nice aroma (characterized as mild citrus/spice), 1:1 ratio of alpha-acids to beta-acids, low CoH, high Linalool, good storage stability, and resistance to hop powdery mildew. The new variety resulted from cross-pollination performed in 2003 in a field in Prosser, Wash., United States and has been asexually reproduced in a nursery in Prosser, Wash., United States.
