How to 'Translate' a recipe to a MiniBrew Brewery Portal recipe

First of all, please keep the specs of the MiniBrew in mind when creating your own recipes: https://minibrew.zendesk.com/hc/en-us/articles/360011780660-What-are-the-technical-capabilities-of-my-Minibrew-system-

When you take the original recipe see if the fermentables are showed in percentages. Let take this recipe for example: Fuller's London Pride

United Kingdom - Golden Promise - 90.4% - 7.26 kg

United Kingdom - Crystal 90L - 8.5% - 0.68 kg

United Kingdom - Chocolate - 1.1% - 90.71 gram = 0,091 kg

Batch size 12 gallons (ending kettle volume) = 45.42 liter -> efficiency 80%

ABV 4,39% - IBU 36,59

MiniBrew batch size = 5.5 liter - 

45,42 / 5,5 = 8,26 -> this is what we use to divide the grain bill (still based on 80% efficiency)

United Kingdom - Golden Promise - 90.4% - 7.26 kg / 8,26 = 0,879 kg = 879 gram

United Kingdom - Crystal 90L - 8.5% - 0.68 kg / 8,26 = 0,082 = 82 gram

United Kingdom - Chocolate - 1.1% - 90.71 gram = 0,091 kg / 8,26 = 11 gram

When entering these amounts of malt in the brewery Portal (after entering the yeast and hops) it shows: 3,3 ABV (and it is not brew-able because the malt bill requires a minimum amount of 1,2 kg)

System efficiency 55 - 70 % 

Based on the amount of malt the efficiency is calculated. That is why it makes sense to use the brewery portal (and Excel) to do the calculations. I used Excel to calculate a grain bill and try different amount in the Brewey portal, The original amount x 1,39 showed the required ABV of 4,39%

United Kingdom - Golden Promise - 90.4% - 879 gram * 1,39 = 1222 (1225 shows the correct ABV)

United Kingdom - Crystal 90L - 8.5% - 82 gram * 1,39 = 114

United Kingdom - Chocolate - 1.1% - 90.71 - 11 gram * 1,39 = 15

Hops - 60 minute boil

1 oz	Target = 28 gram / 8,26 (again from 45 to 5,5 liter) 	3,4 gram - 60 min

1 oz	Challenger = 28 gram / 8,26 (again from 45 to 5,5 liter) 	3,4 gram - 15 min

0.5 oz	Northdown = 14 gram / 8,26 (again from 45 to 5,5 liter) 	 1,7 gram - 15 min

1 oz	East Kent Goldings = 28 gram / 8,26 (again from 45 to 5,5 liter) 	3,4 gram - 15 min

Adding just a little extra hops showed the correct IBU. Make sure you enter the correct Alpha Acid of the actual hops you use.

Yeast

I selected the Lallemand London ESB, I entered primary and secondary fermentation duration both 12 days.

Mashing

The MiniBrew Mashing works a little different, I choose this sequence:

30 minutes - 65 degrees Celcius

60 minutes - 75 degrees Celcius

(not sure this is the correct 'translation')
