SubZero Hop Kief (TM)

Introducing Freestyle SubZero Hop Kief™! 

Concentrated lupulin for cold side use, with all the flavour intensity of Freestyle pellets, but added benefits and versatility.  Our SubZero Hop Kief™ is intended for dry hopping and can even be added to the brite tanks prior to carbonation and packaging to give your beer an added boost.  We recommend starting with about at 33% substitution rate, although you can go as high as 50% of the normal T90 pellets in a dry hop. SubZero Hop Kief™ is true-to-lot, delivering the same consistent flavour/aroma profile as the individual hop lot from which it is made.

SubZero Hop Kief™ can be used in ways that traditional pellets can’t, giving you more options with your brewing process.  It can be added super late to lift the flavour and aroma of your beer (immediately before packaging). Our SubZero Hop Kief™ provides efficiency gains, it can be substituted for traditional pellets, giving you more beer yield.  SubZero Hop Kief™ can also deliver attributes that might be hard to achieve with traditional pellets, such as creamier mouthfeel and a complex juicy profile for your beer, helping you achieve a different character than might be possible with various forms of pellets.

Freestyle SubZero Hop Kief™ is made with a process that allows us to extract all the desirable flavour and aroma compounds, unlike other products you may have used.  Many other products claim to be solventless but actually use CO2 as a solvent, meaning that compounds that aren’t soluble in CO2 don’t end up in your beer.  For example, free thiols are not typically solubilized in CO2.  

It’s liquid dry-hop made with a cryogenic, solventless, patent pending separation process. It's all-natural, 100% New Zealand grown hops and designed to deliver flavour intensity, brewing efficiency and new dry hop options.  SubZero Hop Kief™ delivers the full spectrum of flavour compounds in a normal T-90 pellet without the vegetative matter. It is intended for flavour/aroma use on the cold side or whirlpool and not as a bittering concentrate. SubZero Hop Kief™ is produced in an FDA and cGMP compliant food and pharmaceutical manufacturing facility. It contains about 33% USP food-grade ethanol by volume for food safety and ease of use.

DOSING INSTRUCTIONS: SubZero Hop Kief™ is easily dosed in-line when transferring fluid between vessels or dosed directly into fermentation vessels + brite vessels. SubZero Hop Kief™ is partially diluted with USP food-grade ethanol (~33% EtOH by volume).  Lightly shake/swirl the bottle to gently homogenize the contents before use. 

• 275 mL containers hold lupulin equivalent to 5 kg (11 lb) of T-90 pellets.
• 1,100 mL containers hold lupulin equivalent to 20 kg (44 lb) of T-90 pellets. 

Dry-hop T-90 Pellet Reduction:  SubZero Hop Kief™ can be substituted for 50+% of the T-90 pellets in a normal dry-hop. We recommend starting with a ~33% substitution for a highly hop-forward ale.

Pre-fermentation Addition:  Make sure fluid temperature is <140°F (60°C).  We recommend pulling some fluid (approx. 2x the volume of SubZero Hop Kief™ you plan to dose) and mixing gently.  Fluid can be added in the whirlpool or in-line when transferring fluid to a fermentation vessel.

Mid-fermentation Addition:  We recommend pulling some fluid off the FV (approx. 2x the volume of SubZero Hop Kief™ you plan to dose).  Mix gently and this mixture can be pushed into the vessel with an inert gas or simply poured into the top of your vessel.

Post-fermentation Addition:  We recommend pulling some fluid off the BV (approx. 2x the volume of SubZero Hop Kief™ you plan to dose).  Mix gently and this mixture can be pushed into the vessel with an inert gas or simply poured into the top of your vessel.  SubZero Hop Kief™ can also be dosed during transfer between FVs and BVs or even at carbonation with adequate mixing into finished beer.

STORAGE AND BEST-BY:  SubZero Hop Kief™ is new and our shelf-life recommendation may evolve as we get further data. It should be cold stored at -2 to 4°C.  SubZero Hop Kief™ performs best if used within 2 years of processing.  After opening, it should be used within 6 months if the bottle is re-purged with inert gas and stored cold.

TRUE-TO-LOT:  SubZero Hop Kief™ delivers the same consistent flavour/aroma profile as the individual hop lot from which it is made.  It contains all the polar compounds and polyphenols present in T-90s and does not contain a volume of EtOH that would solubilize more hydrocarbons than a typical T-90 dry hop. 

WORKS WITH OTHER HOPS FORMS:  SubZero Hop Kief™ is variety/lot specific pure hops. It combines well with T-90s, T-45s (aka Cryo, Lupomax, CGX, etc.), whole cone hops and/or other hop concentrates (Incognito, CO2 extract, etc.).  We’re not aware of any product incompatibilities.

REDUCED SHIPPING COST: SubZero Hop Kief™ comes in recyclable aluminum bottles that are cheaper and easier to ship and store versus pellets.
