Corn Sugar (Dextrose)

Corn Sugar (Dextrose)

Please select from the following option(s) to see pricing and availability.

Corn Sugar, or dextrose, is used to "prime" your beer to produce natural carbonation in the bottle. "Priming" is the act of adding a small amount of fresh fermentable sugar to the beer just before bottling so that the residual yeast will consume it and produce carbonation in the sealed bottle. We recommend corn sugar for this purpose because it is easy for the yeast to consume and has a neutral flavor profile, meaning it will leave your beer tasting the way you designed it!
Use 4 or 5 oz of corn sugar to prime 5 gallons prior to bottling. Dissolve in 1-1.5 pints of water and boil for 5 minutes to sanitize prior to mixing with your beer.
If your fermentation ended at 68F it will retain about 1 volume of CO2. If it ended at 50F it will retain about 1.2 volumes of CO2. 4 oz in 5 gallons adds 1.48 Volumes of CO2. 5 oz adds 1.84 volumes of CO2 to 5 Gallons.
Suggested CO2 Levels:
  • Cask Ales 1.5 to 2.0
  • Ales 2.3 to 2.6
  • Lagers 2.4 to 2.6
  • Highly Carbonated Beers 3.0+
    • Champagne is 6.3 and requires a special bottle.
To convert from volumes to g/L:
  • multiply volumes x 1.96.
Can also be used to boost your Original Gravity without impacting the beer's flavor profile. Adds 1.042 points per pound per gallon (PPG) to your specific gravity.
  • Dextros Needed (lbs.) = (Actual Volume * (Target Gravity – Actual Gravity)) / 0.042

It’s corn sugar
It’s corn sugar, I wouldn’t know how to tell good or bad. No bugs in it, that’s got to be good right?

Sweet! Corn Sugar
As a home brewer you can always use a few lbs of corn sugar to use as needed.

Can never have too much of this on hand
I bottle, so I use a lot of dextrose for that alone. But I'm brewing a couple Belgians in the near future, so will burn through a few lbs. of it in the boil.

Great and versatile product.
Use it for bottling and to increase alcohol and lower specific gravity in IPAs.

Worked as expected. It dissolved nicely into boiling water and eventually provided food for my yeast.
