Mead Calculator Help – Got Mead? The Largest Mead Resource on the Web

How to . . .	What to do . . .
What Specific Gravity (SG) will my honey produce?What Potential Alcohol (%ABV) will my honey produce?	Click the Target Volume box, and enter your batch volume Click the Additional Sugars #1 box, and Select the Type (Honey) & Quantity and enter how much honey/fruit in the recipe (eg, 15 Pounds of Honey) Click anywhere on the web page, or click Calculate to get your answer
If I add Extra Honey or Fruit to my existing mead, what will be the new SG or %ABV	Enter your existing Specific Gravity (SG) that you have measured or previously calculated as the Current Gravity Enter your existing Volume as the Current Volume Click the Additional Sugars #1 box, and Select the Type (Honey) & Quantity and enter how much additional honey/fruit to be added (eg, 3 Pounds of Honey) EITHER Click the Target Volume box, and enter your batch volume IF you are aiming for a particular new volume or know what the volume will be due to additions OR Click the Target Gravity box, and enter your required gravity IF you are aiming for a new specific gravity or Potential Alcohol Click anywhere on the web page, or click Calculate to get your answer
How much Honey/Fruit do I add to produce a particular amount of Alcohol (%ABV)?	Enter your existing gravity and volume IF it is different to 1.000 (water) as the Current Gravity and Current Volume Click the Target Gravity box, and enter your desired Specific Gravity (SG) OR your desired Potential Alcohol (%ABV or %ABW) Click the Target Volume box, and enter your batch volume Select the desired Type and Quantity Unit for the Additional Sugars (but leave the check box un-ticked) Click anywhere on the web page, or click Calculate to get your answer Note that you may enter a few Additional Sugars (eg, some honey and some fruit), and the next unchecked “Additional Sugars” will be updated with the additional amount required to produce the desired SG or %ABV
Can I make all the units Metric or Imperial?	Click the Preferences for Measurements that you require (Metric or Imperial, or US) Note that you can still enter individual values as a different measurement system by selecting the desired unit from a check list for that item (eg, add 3 pounds of honey, and 0.5 Kilogram fruit)
How do I Convert from one unit of measurement to another?How many US Gallons is 4 Imperial Gallons?	Change a drop-down selection and the values change with the units This allows temperature, Specific Gravity, Potential Alcohol, as well as volume and weight to be converted. The Quantity of “Additional Sugars” are relative to Pounds of Honey – so volume quantities are volumes of Honey that are equivalent to Pounds of Honey, and is NOT a direct volume to weight conversion.
What is the difference between Current Gravity and Target Gravity?	For a new batch, you are starting with water and adding honey and other “sugars” to the water, so the Current Gravity is 1.000 (water)For making additions to an existing batch, measure the Current Gravity of the must prior to making additions. The Specific Gravity of the must should change to the calculated Target Gravity once you have made some additions of honey or other “sugars” . Hence, the default value for Current Gravity is 1.000 or the value for water. The Target Gravity is calculated as the current plus the gravity due to the addition of “sugars” . So change the current gravity to match the gravity of your must prior to making additions.
What if my Fruit doesn’t match the amount of sugar listed in the calculator?	Edit the Sugars Content to match the amount of sugars in your specific fruit. If you change the Type selection, then the Sugars Content value will be changed from what you manually entered. This utility does not store any values you enter ready for the next time you use the calculator, but reverts to defaults each time the calculator is run.The Sugars Content values are mostly derived from average figures quoted by the USDA, et. al. Fruit changes in sugar content from season to season, and variety to variety, so the values provided are only to provided in this utility are an indication of the expected result you will achieve. Actual hydrometer readings will provide the real indication of the sugar content in a must.If a fruit is missing from the list, then please post a request on the forum to have this fruit added, and if possible, locate an average sugar content figure for the fruit from the Internet, and provide the sugar content figure along with the request.

Potential Alcohol Conversion Utility

How to . . .	What to do . . .
How does the Potential Alcohol Conversion utility work?	The Potential Alcohol Conversion utility takes the difference between two Specific Gravity measurements, and calculates the %ABV or %ABW by converting the SG value to a Baume. The Baume value is assumed to match the amount of Alcohol able to be produced from a must starting and finishing at the two supplied SG values.
How do I determine the potential Alcohol that would be produced if the yeast used up ALL the honey in the must?	Enter the Original Gravity eg, 1.120 Enter the Final Gravity eg, 0.996 (but this is dependant on the capability of your yeast) Click anywhere on the web page, or click Calculate to get your answer
How do I determine the potential Alcohol that would be produced if the yeast stopped at a particular Specific Gravity?	Enter the Original Gravity eg, 1.120 Enter the Final Gravity you desire or have measured eg, 1.010 Click anywhere on the web page, or click Calculate to get your answer
How do I determine the Original Gravity that would provide the Potential Alcohol I desire?	Enter the Final Gravity of whatever sweetness you are aiming for, eg 1.010 Enter the %ABV (or %ABW) that you desire eg, 12 (for 12% Alc) Click anywhere on the web page, or click Calculate to get your answer (the SG at which to start the fermentation)

Blending Calculation Utility

How to . . .	What to do . . .
How does the Blending utility work?	The Blending utility uses Pearson Square formulae to derive the proportions that will result from blending two liquids.The blending values can be: %Alcohol (reduce or fortify), Specific Gravity, Acidity (g/L) some other property of the liquids . . .
How do I determine the proportions of mead and vodka when Fortifying my mead or wine, to achieve a desired %Alc of 18%?	Enter the %Alc of your wine and Vodka as Value#1 and Value #2 respectively (eg, 12 and 20) Enter the required Blended Value of 18 as the resultant blend (same “unit” as the above two values, and must be between the two values). Enter the volume of mead or wine you have as Volume #1 (eg, 1 for 1 gallon) Click the radio button beside Volume #2 to identify what you want to calculate Click anywhere on the web page, or click Calculate to get your answer (3 gallons of vodka required, making a total of 4 gallons in total of fortified mead)
How do I determine the resultant Specific Gravity when I Blend two musts together (sg=1.160 & 1.095)?	Enter the two SG values as Value#1 and Value #2 respectively (eg, 1.160 and 1.095) Enter the volume of the first mead or wine as volume #1 (eg, 2 for 2 gallons) Enter the volume of the second mead or wine as volume #2 (eg, 1 for 1 gallon) Click the radio button beside Blended Value to identify what you want to calculate Click anywhere on the web page, or click Calculate to get your answer (SG=1.138)
How do I determine the two volumes required to achieve a %Alc of 13%, when I mix two meads of 16% and 10% together to give a TOTAL volume of 5 gallons?	Enter the two %Alc values as Value#1 and Value #2 respectively (eg, 16 and 10) Enter the Blended Value of 13 Enter the Total Volume of 5 (and remove any other volume values) Click the radio button beside any one of the three Volume values, to identify what you want to calculate Click anywhere on the web page, or click Calculate to get your answer (2.5 & 2.5)
