Dosage instructions for ritchies isomerised hop extract

Post by TheSumOfAllBeers » Tue Aug 14, 2018 2:38 pm

I picked up some of this to add the bulk of the IBU to raw extract ale I am making.

But it has no instructions on correct dosage.

It says it is 'good for 45 L' but doesnt say what IBU level it would bring 45L up to.

Anyone know how much to use to add 20 IBU to 60L of wort ?

1ml pipette and a pint of beer might be your best friend here!

Iirc I had this same issue with a batch of under bittered beer (800L of it) and emailed Ritchie's. They were fairly swift at getting back to me with the proper dosage to calculate the addition properly, so send them an email. Why they don't give it out on the packaging is beyond me

They were quick about replying.

10ml extract in 60L will add +10 IBU roughly.

So the whole bottle on its own will get me into my 25-30 IBU sweet spot
