qBrew - Homebrewers Recipe Calculator

 qBrew is the beer recipe calculator of choice for homebrewers looking for a free software program that's intuitive and easy to use. qBrew comes installed with it's own beer style, grain and ingredients database and is ready to use right away with minimal setup. qBrew will automatically calculate the gravity, color and bitterness of your recipe as you add in grains, extracts, adjuncts and hops, it works for both ales and lagers as well.

 ** Special considerations: The qBrew application was written by David Johnson, last updated May 25th, 2008 and is also available as an open source download from his original qBrew Site. While the original .qbrewdata database file did not contain ingredients for Mr. Beer products users of qBrew have added them and other hop varieties, yeast types and fermentables.

 Many brewers, myself included, have devoted their time to researching and adding updates to the original qBrew database so that we can share it with other brewers. I would like to thank  EricG at the Mr. Beer Community for providing additional ingredients and explaining how to get the most out of your recipes. Finally thank you to the countless other brewers out there who have shared their understanding of the inner workings of the qBrew formulas and how they are used to calculate your recipe's characteristics.

 qBrew lets you to override any of the numbers associated with a given recipe ingredient, in case your current supplier has a different alpha acid percentage for the hops your using or for differences in grain or brewing efficiency. The default recipe numbers are loaded into qBrew from the database and can be changed in your recipe to match your actual numbers without changing the database default numbers.

 The upper section of qBrew is where you enter the recipe title and brewer name and select the style of your recipe. The characteristics of the style are then displayed showing the minimum and maximum numbers for the Original gravity, Bitterness and Color. As you enter your ingredients into the lower section of qBrew the characteristics of your recipe are calculated and displayed in bold letting you know how the ingredients can influence your expected results.

      Click here to download Screwy's latest qBrew database (qbrewdata-MAC) 

 Extract the compressed qbrewdata.MAC file from the screwy-qbrewdata-MAC.zip file you downloaded and rename it to qbrewdata (remove the .MAC extension).

 Open a new Finder window, go to your Applications folder and Ctrl+click the qBrew application. Select 'Show Package Contents' then navigate to Contents->Resources and rename the qbrewdata file in this folder to qbrewdata.orig.

From the original Finder window, drag the new qbrewdata file into the Resources folder in the new window. Restart and qBrew will load this latest database file when it runs.

You can also copy and paste the file into the new directory using Command-C and Command-V respectively instead of having to jump between windows.

 
Setup qBrew Defaults:
  Run qBrew and select Configure from the Options menu then the Recipe tab.

Select Pellet for Hop type and enter 2.13 gallons for the Mr. Beer keg size

  Verify that the default settings are setup on the Calculations tab. 

.75 Mash Efficiency Default Calculations Setting

Example Mr. Beer based recipe:

Mr. Beer Extracts Weigh 1.21 Pounds

 Grains: Enter fermentable grains, extracts, sugars and fruit.

 For creating recipes you first enter a new line on the grains tab by right clicking in the lower section and selecting 'Add Ingredient'. Left click on the default grain inserted into the lower grid and select the type of extract you are using in your recipe. You then enter the weight of the extract by left clicking in the 'Weight' column and adjusting the default value to match your recipe, for instance Muntons extract cans weigh 3.3 pounds while Mr. Beer extract cans weigh 1.21 pounds. Both unhopped malt extracts (UME) and hopped malt extracts (HME) are available for entry on the grains tab.

For Hopped Malt Extracts (HME) Use A 5 Minute Boil Time

Hops: Enter the variety of hop, weight, alpha acid, boil time and type.

  Insert a new line and change the default hop variety to add to your recipe by selecting it from the drop down list and adjusting the weight, alpha acid, boil time and type to match your recipe. The hops tab saves your hop variety and their current percentage of alpha acids as well as the boil times used for this recipe. Screwy's .qbrewdata database file contains the full list of Mr. Beer HME values.

Example: If you were going to add more bitterness to this extract recipe you might add a new line for 1/2 ounce of Cascade hops boiled for 30 minutes. For flavor add another new line for 1/4 ounce of Cascade hops boiled for 12 minutes and a new line for 1/4 ounce of Cascade hops boiled for 5 minutes for aroma.

Special Note When Entering Hop Additions: If you want to add up all the IBUs for your hop additions enter all your hops before adding in your grains. As you add in your grain additions qBrew's built in formula will begin subtracting the malt's sweetness from the hop's bitterness in order to indicate the balance of the recipe. The formula qBrew uses to calculate this balance is the same one used by my Bitterness Balance Calculator to display the recipe's overall balance between hopped bitterness and malt sweetness in a hopped beer style.

The formula takes into consideration the beer's original gravity, actual attenuation and bittering level but does not take into account phenol, ester or other complexities. The beer drinker should use the desired IBUs as a reference point and decide for themselves what they consider to be balanced.

Select The Type Of Yeast And Quantity

Miscellaneous: Enter the type of yeast used for fermentation

  Insert a new line and change the default yeast value to add to your recipe by selecting it from the drop down list and adjusting the weight if necessary.

Enter Recipe And Batch Notes For Future Reference

Notes: Type in any recipe and batch related notes for the recipe, this will come in handy in the future when you try to reproduce the great beer you just drank. All brewers should take notes and keep records of the beer recipes they brew, including the brewing process that was used. If you're like me you will want to tune and tweak your favorite recipes and brewing processes trying to improve on them each time you brew.

Calculated Characteristics For Your Recipe

Characteristics: We setup qBrew to use a realistic mash efficiency of .75 as this is an  acceptable average efficiency for most home brewers. Any differences in the percentage of alcohol by volume (ABV) calculations performed by qBrew and those stated by any extract supplier are related to differences in efficiencies used when determining the extract's rated ABV.

  Good brewers rely on consistency when calculating their recipes and during their brewing process. qBrew lets you to create recipes based on beer's key ingredients and then calculates the expected characteristics of the beer using formulas widely accepted by homebrewers. As you brew your recipes some fermentable volumes or boil times may need to be tweaked as needed to match your brewing process.


Hop Calculation Tip: When entering all your hop additions on the 'Hops' tab before entering any ingredients on the 'Grains' tab qBrew will calculate the IBU for those hops. Record this number in the 'Notes' tab for later reference as this number will change when ingredients are entered in the 'Grains' tab.
