• Foam stability
• Foam lacing & cling
• Anti-microbial

Usage & Methods 

• Use 3 – 6 ppm for improved foam
  • Good – add product to empty vessel and push with nitrogen (NOT CO2) into beer line when starting to fill tank
  • 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
  • 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 & Suggestions 

• Tetra contribute an upfront non-lingering bitterness and 1 ppm of Tetra will contribute 1 IBU 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
• Product will freeze – must ship next day air during winter months

Package & Storage 

• Only use nitrogen to purge container headspace free of air. CO2 will react causing precipitation
