RHO ISO Extract 35%
A pure, aqueous solution of the potassium salts of reduced (rho) iso-alpha acids produced entirely from CO2 Extract
OVERVIEW
Rho – 35% is a pure, aqueous solution of the potassium salts of reduced (rho) iso-alpha acids produced entirely from CO2 Extract
Rho – 35% gives protection from light-struck flavor when used as the complete source for hop-derived bittering or in conjunction with other reduced hop products
Rho – 35% will give a slight enhancement to beer foam stability compared to an otherwise similar beer bittered in a conventional fashion
FLAVOR
Rho provides only bitterness. Many brewers consider that Rho imparts a particularly pleasant, “soft” bitterness to the beer.
