Notes

Fibonacci Ale uses the Fibonacci number sequence for the hopping regime and boil timings.
Modified 18 Feb 2021 - Changed yeast to Fermentis US 05

Changed hops to Northern Brewer and EKG
Reduced Wheat and Munich Malt loading.
Recipe has been formulated for balance and drinkability over a number of iterations whilst still incorporating Fibonacci sequences
Specific style is not important.
