This is an experiment. Hopefully its drinkable.
Amount of ginger varies by recipe, with some calling for upwards of 2kg, others calling for less than 200g.
1st set of ginger in at 20mins then 2nd set at flameout. This is meant to balance the flavours of the ginger against having (as some noted) either not enough ginger flavour to be perceptible vs a "metallic" ginger taste.
IBU target set on the basis of IBUs/OG points and alignment with a blonde Ale or white IPA.
Hops selected based on the ability to pull favours that will work well in a ginger IPA (focus on citrus, passionfruit, grapefruit).
Fermentable selected to provide a clean front end, with a slight citrus availability.
Didn't want the alcohol content too high.
Some recipes call for champagne yeast, some focus on a ginger yeast starter, some say simple, clean yeasts like US-05 is fine. decided on US-05. If this turns out ok, might try to create a ginger yeast starter next time.
