Ok thanks... That's another thing I need to dial in... My water volumes. The spreadsheet has been high which leads to lower o.g and waste. But I still love this thing. Thanks
I'm using BeerSmith instead of their spreadsheet. When I looked at the sheet a few months back it had some obvious errors. For example, the Loss to Boil field was set to a fixed value of 3 instead of a calculation. I also found that the sheet, when working, did give me too-high water volumes as you found.
If you want to keep using their sheet, try adjusting the grain absorption rate. I think their suggested value of 0.1 gal/lb is too high. I found through
using the equipment that a more accurate value for me was .062 gal/lb. That includes mashing the grain bed with a pot lid to help it drain. YMMV!
I did get BeerSmith to play nice with my Nano Home. I had to enter these values.
BIAB Grain Absorb: 0.4960 fl oz/oz (
Converted from .062 gal/lb. I determined this value by seeing what ACTUALLY happened in my first brew day. BeerSmith and CBS default values both gave me too much final volume.)
Mash profile: check "BIAB Mash with Full Boil" so that sparge settings are turned off.
Finally, in the Equipment Profile I had to set the hourly boil-off rate. For me, that is 1.34 gal/hr. I determined that with a test run with water, using a 7 gal starting volume and element power of 65%. Once it warms up here I expect I will need to change this value.
Things are starting to click over here. My last 3 brews have been my best to date. Part of that is a better understanding of water chemistry and better kegging practices, but the Nano Home ain't hurting.
