Hopsteiner Launches Redesigned Calculators For Brewing, Extract Product Dosing Rates

Yakima, WA — Hopsteiner, one of the largest hop growing, trading, breeding and processing firms in the world since 1845, has launched their newly redesigned brewing calculators and the all-new Extract Product Dosing Rate calculator. Hopsteiner’s calculators determine extract product dosing, keg carbonation (PSI), beer priming (CO2), beer color standard reference method (SRM), bitterness (IBU), and alcohol-by-volume (ABV).

“We’re thrilled to be able to provide such great resources for our clients and brewers all over the world,” said Bill Elkins, Sales for Hopsteiner. “The calculators are used to assist in formulating beer recipes and aid in the brewing process, providing the needed formulas to create delicious beer.”

The following calculators are now live and available to brewers:

ALL NEW: Extract Product Dosing Rate Calculator

Used to determine the dosage of CO2 hop extract you need to target a specific International Bitterness Unit (IBU). Hopsteiner’s hop extracts are made from hops via carbon dioxide CO2 extraction. Extracts retain the hop’s α-acids, β-acids, essential oils, aroma and bittering characteristics. Hop extracts are highly-concentrated hop products that provide convenience, efficiency, stability, consistency and flexibility to brewers.

Keg Carbonation (PSI) Calculator

Estimates the correct regulator setting that force carbonation of beer requires. Calculates keg pressure in Pounds per Square Inch (PSI) to set the regulator at given temperature, and volumes of CO2 when kegging.

Beer Priming (CO2) Calculator

Estimates how much priming sugar to add during bottling. The beer you’re about to package already contains CO2 that has naturally occurred as a byproduct of fermentation. The amount of sugar needed is fermentation temperature dependent. The remaining yeast ferment the sugar and this produces CO2. This calculator includes the residual amount of CO2 present in the beer due to fermentation, and works for corn sugars, table sugars and dry malt extract. Sugar is added at bottling time.

Beer Color (SRM) Calculator

Estimates how light or dark your beer will be based on known grain color values assigned to grains, extracts and adjuncts. It also factors in the quantity of the ingredients to calculate the final beers approximate color profile using the Malt Color Units (MCU) Formula which is fairly accurate with light colored beers, but becomes increasingly inaccurate for beers with SRMs over 10.

Bitterness (IBU) Calculator

Use your target batch size and original gravity to estimate how bitter your beer will be based on up to 6 hops additions. Calculations have been adjusted for full and partial mash batches, and takes into consideration, the average utilization differences between whole leaf hops and pellet hops. IBU Scale starts at 0 for beers with no bitterness (fruit and sour beers), and goes all the way up to 120 for highly–bitter beers.

Alcohol-By-Volume (ABV) Calculator

Estimates your initial and final gravity readings, and supports both Plato and SG reports for apparent attenuation, and calories. When using a hydrometer, you’re measuring the specific gravity (SG) of your beers density as is relative to water. Because alcohol is less dense than water, by measuring the difference in your beers density before it begins fermentation, and creates the less dense alcohol, you can then measure the alcohol change-by-volume.


Hopsteiner (S.S. Steiner) was founded in 1845 in Laupheim, Germany. Today, Hopsteiner is one of the largest international hop growing, trading, breeding, and processing firms in the world, with operations in nine major regions. Hopsteiner continues to invest in new technology to remain at the forefront of quality, efficiency and sustainable practices.
