I'm planning to brew a summer ale with kolsch yeast and galaxy hops.
Extract with steep grain
250g crystal malt
1.5 kg pale malt extract in boil
1.5kg pale malt extract at knockout
Hops galaxy 14,3%
I'm a bit lost with the quantity of hops I should use and for how long I need to boil them,
IBU should be around 15 and lots of passion fruit flavor...
Need dry hopping as well ?
Need help please to finalise this recipe,and comments on the ingredients to see if it's sounds good or not?!
