Notes

Fibonacci Ale pays homage to Fibonacci, a 13th century mathematician in using the Fibonacci number sequence for the hopping regime and boil timings.
Modified 18 Feb 2021 - Changed yeast to Fermentis US 05
Modified 15 Dec 2021
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, however can be categorised as a Pale Ale.
