Hop Oil Products

Pure Hop Oils

Pure hop oils usually have a very pale green/yellow appearance. They have been on the market for many years, and give beer hop aroma without imparting any bitterness. Traditionally, hop oils are added to the kettle late in the boil, which is known as "late hopping," or they are used for dry hopping. It is generally agreed that the addition of hop oil to filtered beer does not produce a satisfactory flavor since some contact time with yeast is necessary to remove "raw hop," "tobacco," and "grassy" notes.

Oil-Rich Extracts

Oil-rich extracts are usually yellow/brown in color and less viscous than pure resin extracts. These products originally were developed in the United Kingdom as a replacement for dry hopping.
