HOPS TETRA EXTRACT

Tetra ISO Hops

• 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.
• Dosage is based on the product concentration, an estimated or known utilisation and the desired intensity of bitterness in the beer.
• The fact that the perceived bitterness of Tetra is about 1.0 to 1.3 times the bitterness of iso-alpha acids derived from conventional hop products must taken in to consideration.
• The correct dosage of Tetra must be determined through trials at the brewery.
• Tetra is stable two years from the date it was packaged if stored under the recommended conditions stored at 5° – 25º C in a sealed container.
