Rho Iso-Extract 30%

Description

Rho is a pure, aqueous solution of the potassium salts of rho-iso-alpha acids produced entirely from CO2-extract. Rho gives protection from light-struck flavor when used as the complete source for hop-derived bittering or in combination with other reduced hop products. Rho will provide a smoother, non- lingering bitterness compared to regular iso-alpha acids.

Usage & Methods 

• Kettle = 45% – 55% utilization
• Post-fermentation = 70% – 85% utilization
• (Kettle) Add anytime during boil
• (Post Fermentation) :
  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
• Inject on suction side of beer transfer pump

Notes & Recommendations

• 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 

• Open containers should be used within 3-4 weeks and headspace purged using nitrogen (avoid using CO2)
• Rho 30% may form crystals which can be re-dissolved by warming container overnight
