Tetra Iso-Extract
A homogeneous, yellow to amber, clear aqueous solution; mobile and free flowing at all normal storage and use temperatures. Miscible with demineralized water and alcohol.
Overview
Tetra Iso-Extract (Tetra) is a pure, aqueous solution of the potassium salts of tetrahydroiso-alpha acids produced entirely from CO2 hop extract.
Tetra will greatly enhance beer foam when used as a post fermentation replacement for a proportion of the normal bittering.
In the absence of normal alpha and iso-alpha acids, Tetra will give virtually complete protection against development of light-struck flavors.
LIGHT STABILITY
Tetra will only provide protection from light- struck flavor in the complete absence of normal iso-alpha acids. Tetra can be used in conjunction with Reduced Iso- Extract to achieve light stability, improved foam and balanced bitterness.
