This is one of those things that the folks here at the shop have been using in their own brewing process for a couple years and it only just recently hit us that offering it as a kit would be very helpful after telling people about it on a regular basis.
Use this assembly to dose any liquids into sealed kegs of beer in an oxygen free and sanitary way. It even works on kegs that are under some pressure and carbonated. If you try to open the keg to add things, you're risking oxygen damage and in the case of carbonated beer you might also cause a beer volcano!
Things you might want to inject into a keg:
Finings like dissolved gelatin or Biofine.
Body enhancers like liquified Maltodextrine or Lactose
Preservatives such as Ascorbic Acid, Potassium Metabisulfite, Potassium Sorbate
Tinctures, flavor extracts, etc.
How to use it:
The 60mL syringe is connected to the gas ball lock connector. We also include a ball lock male to hose barb connector to open up the poppet valve in the connector and to be able to suck up your injectable solution.
- Insert the ball lock barb into the gas QD and submerge the barb into some sanitizer while withdrawing the syringe plunger. Be sure to fill the syringe at last as full as your injectable product will occupy. Let it soak for a minute and then dispense all the sanitizer out of the assembly.
- Drop the barb down into the solution you want to inject and suck up the amount you want.
- Remove the ball lock barb adapter, trapping the injectable liquid in the system.
- Spritz the ball lock post on your keg with some starsan or your sanitizer of choice.
- Attach the QD to the gas post while pushing the plunger in firmly. When all of the product is dispensed into the keg, pop the QD off and then you can stop pushing the plunger in.
IMPORTANT! If your keg is under any kind of pressure, it's best to vent it down to under 10psi. Regardless, be sure to hold pressure on your syringe plunger as you make the connection to the keg's gas port. Since the syringe plunger is approximately 1 square inch of cross section area, the plunger is being pushed outward at the same pressure that's in the keg. 10psi is about 10 pounds of force pushing out. Anticipate this. If you don't hold the plunger in with adequate force, it will be blown out of the syringe along with the injectable liquid. You'll take a shower and use colorful language. You've been warned so be mad at yourself.
You can clean the assembly by inserting the ball lock barb adapter and repeatedly sucking up some hot (tap hot, not boiling) water and shooting it back out a few times.
