Thanks for the info Scott. I decided to do the mashout on the spot and thought I recalled some people doing in in the mid 170 range - Two mistakes: deciding to do something on the spot and going off memory! Since, from what I've read, the point of the mashout seems to be to denature the enzymes and ...

Right... other things being equal, with a longer boil time, in order to reach the same final volume, you would need a higher starting volume. A higher starting volume could mean less grain needed but yes it's complicated (for one, enzymes needed for conversion are also diluted). A half gallon differ...

Hi Streamer, I finally got to trying to brew the Amarillo APA now that the temperatures have cooled down (I haven't invested in a temp controlled fermentation chamber.) This was my first time using biabacus. I've uploaded the file with some of the numbers. Summary: For my approx. 10 gal kettle, I us...

Yes Scott, good information. Based on what you're saying it makes sense to check the aa value of hops before boil (if I can find a reliable standard procedure) at various hop ages and compare that to what is listed on the package. Of course translating that to actually bittering (i.e. IBU) is depend...

This is an interesting question... I subscribed to this thread and am interested in any new info you find. After a little searching I found the ASBC method for IBU analysis and it looks like I have the resources to do it so I might be doing a little experimenting myself on my samples! It would be ni...

I think that the value in module X relates to adjusting for liquid retention by grain in the grain bag? The value that's entered in the file looks like it should only reduce your volume by about 1 L so I agree that there must be something else contributing to the low VIF and OG. The changed value fo...

I noticed that in the All Amarillo APA file the default Loss from lauter value is adjusted to 0.4 L/Kg in Module X. Steamer didn't enter this value... it is there in the original file. In Scott's file this field is blank. The changed default value in X does alter the TWN by about 1.2 L. Not sure how...
