Hi there,
This is my second post. I am about to launch myself into AG via BIAB. For my first attempt I want to do NRB's All Amarillo APA. I have checked out the calculator and cannot see how I can enter the fact that my Urn is 40 litres, not the 70 litres quoted. The diameter of my urn is 33 cm. I will be using 6.5 kg of grain (just evened out the recipe) and want to know how much water I need for the mash. XL terrifies me but I guess I will have to come to terms with it. Hope somebody can steer me in the right direction.

Hi Bob,
You don't need to put in the urn capacity, the important thing is the diameter as that is part of the evaporation calculation. Once you have put in the needed figures i.e brew length, gravity etc, then you just need to look at the approx. mash volume and if that is below you urns capacity then your good to go.
BTW NRB's AAPA is a top beer and you should enjoy it
Hope this helps, and good luck with your first Biab, I'm sure you wont be dissapointed.
