EBC Calculation

[dcq1974]

Hi All
I'm sure this has been asked many times before however, is there a standard formula to calculate/estimate EBC of a recipe containing different Malts such as Pale, Crystal, Black, Roasted Barley etc?

I realise this can be done with colour charts or a spectrophotometer, just recall it can be estimated for a brew recipe?

Any help greatly appreciated

Hi Darren,

The best little bitterness calculator that I have found is freely available on the 'net & called "Tinibuw". For a general all-round calculator you try the YoBrew Calculator which is also free.

For each coloured ingredient in the mash tun:
Multiply the weight in kg by the colour in EBC
Add the results for all the ingredients together
Then multiply the total by 10 and then by the mash efficiency as a decimal fraction and then divide by the volume brewed.

With coloured ingredients in the copper, do the same but without the mash efficiency.

Add the two numbers together.

5kg pale malt (5 EBC) = 5x5 = 25
0.265kg Crystal (130EBC) = 0.265 x 130 = 34.45
Total = 59.5

Mash efficiency 75%. (0.75) thus: 59.5 x 10 x 0.75 = 445.8

Divided by the volume of 25 litres = 445.8 / 25 = 17.8 or 18 EBC AsNearAsDammit

Do the same thing with the copper syrups, but without multiplying by the mash efficiency, and add it to the above.

Otherwise use the BeerEngine software, which will do it all for you.
