I was wondering if someone would be able to answer my question regarding the stage in partial mash brewing that the brewer “tops off to desired boil volume” (to quote NB PM instructions).
For as well explained as NB’s instructions are, I think this instruction which is simply stated is perhaps more complex, and for me, something I might be getting wrong.
Doesn’t the amount of water in your boil greatly affect whether or not your OG will be on target? For me, I think a common problem I have is topping off either too much or not enough, seldomly I hit my target OG AND have a perfect 5 gal. Lately, I’ve prioritized hitting my target OG, but in doing so have sacrificed a full 5 gal carboy.
I’d love a advice on this stage. How does one figure out their ‘desired boil volume.’ Is it better to have a lower boil volume and top off with more h20 at the end? Or, better to have a higher boil volume and top off with less?
Thanks in advance,
