Actually nothing, turned out fine. Just experimenting with how much of a noticeable difference it makes giving the yeast a few days head start on the wort without the fruits.

There’s a lot of ‘folk wisdom’ in the brewing world I’ve found. Recipes which claim “you must do X” or “if you don’t do Y, it won’t work”. So I like to test different theories and see what’s true and what’s superstition.
