Balanced Bitterness, Light-Stable Performance

Reduced Isolone is designed for brewers seeking a well-rounded, moderate hop profile. Crafted from alpha acids and converted into di-hydro alpha acids (rho), it delivers 60–80% of the bitterness intensity of iso-alpha acids while ensuring light stability. Versatile and efficient, it can be seamlessly incorporated at the brew kettle or post-fermentation to fit your process.
