I’m brewing the same IPA recipe for 4 years now. But since my last 2 batches there is a change in flavour.
The only thing that i have changed is a solenoid valve in the brewing system. But it’s just valve made of nylon. Do you think the new valve can change the flavour of the beer?
The valve is replaced is this one: https://tameson.co.uk/solenoid-valve...10bar-nbr.html
Do you think that i also should contact my hop supplier maybe he changed deliverd hop from an other farm or something?
Thank you in advance
