Description

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.
  • Dextrose Needed (lbs.) = (Actual Volume * (Target Gravity – Actual Gravity)) / 0.042

Which sugar is better dextrose or cane for making wine ?
FRITZIE DELINCE on Nov 2, 2023
BEST ANSWER: No expert, but it probably depends on what you are doing. If it's for fermentation then I don't think it matters. If fermentation is complete it's all alcohol and co2 in the end. Though I hear cane sugar is slower because it is harder for the yeast to breakdown. If you want it for back sweetening then you will get different sweetness profiles.
Is this glucose anhydrous or monohydrate?

Perfect for boosting alcohol nd carbonating
Sometimes I add 1/2 a lb or so during fermentation to get a bit more ABV. Works great at carbonating beer durring bottling time.

Yeast-approved. Yeast-endorsed. Yeast-consumed.
It’s sugar! Made from corn! While I haven’t personally sampled it, the yeast gave it an enthusiastic (albeit proverbial) two thumbs up!
Used in a Mangrove Jack’s Cider kit, finished out clean and dry.
