Hexa Iso-Extract (9:1)

Description

Hexa Iso-Extract is an aqueous solution of the potassium salts of hexahydro-iso-alpha acids produced entirely from CO2-extract. Hexa will greatly enhance beer foam when used as a post fermentation replacement for a proportion of the regular bittering. In the absence of normal alpha and iso- alpha acid, Hexa will give complete protection against development of light-struck flavors.

• Technical Product Data Sheet
• Safety Data Sheet

Advantages

• Light-stable
• Foam enhancement
• Sensory bitterness is similar to iso-alpha acids

Usage & Methods 

• 3 ppm up to 5 ppm for improved foam
• Include link for bench-top testing in bottles or kegs
  1. Good – add product to empty vessel and push with nitrogen (NOT CO2) into beer line when starting to fill tank
  2. Better – Add product to empty beer keg and fill with pH 8-9 adjusted de-aerated, de-ionized water and push with nitrogen (NOT CO2) into beer line when starting to fill tank
  3. Best – meter the concentrated product into transfer stream using a diaphragm pump. Attempt to delivery evenly throughout 80% of the transfer of beer. Dispense solution into the beer transfer stream pre filtration

Notes & Recommendations

• Hexa contributes a bitterness profile like that of iso-alpha acids. 1 ppm of hexa will contribute 1 – 1 IBU’s of bitterness
• Post fermentation for best utilization and efficiency
• Inject on suction side of beer transfer pump
• Do not add to DE slurry tanks
• Make sure introduced at least 5 Meters upstream of filter
• Diluting with beer lowers utilization and can result in precipitation of resins

Package & Shipping

• Product will freeze – must ship next day air during winter months
• Only use nitrogen to purge container headspace free of air – CO2 will react causing precipitation
