Adding a hint of fruit

[grubble88]

Hi folks,
Recently attended the Coventry beer festival.Most enjoyable.Amongst the beers on offer was a rhubarb and custard ale.Despite my initial thoughts it was really very good.
So I am thinking of adding a different flavour to my next brew .Has anyone got any recommendations on how to do this.My son says he as heard of people using fruit infusion teabags to add a subtle flavour.
I would be interested to know if anyone as tried this and if so what quantity would be involved.
Many thanks,

I've used orange zest a few times which works really well. 40g per 25L.

The only thing i`ve added, though not a fruit is elderflower,
15g in a 23ltr batch but thinking of adding 20g next time i brew it.
