There are characteristics of grain that vary with each crop and where it was grown, etc., as well as variations that are caused by how it was malted. That information can generally be obtained from a Malt Analysis sheet that sometimes accompanies the grain (at least for very large orders such as for commercial breweries). BTP presumably uses that information (at least some of it) for it calculations.

The BTP grain database contains information about most popular grains from many suppliers, but users also have the ability to 'add' new grains, and to 'edit' existing grains (or new ones) to make changes in that information. That information should ideally come from the analysis sheet provided by the maltster, but might be obtained from a website, etc. Eventually I hope we can obtain a list of the absolutely essential fields needed by BTP for its calculations.

The following fields appear on the Grain Editor panel, with the following meanings/purposes (some technical information was obtained from this Article by Greg Noonan).

Name
self-explanatory
Origin
country or region where grown
Supplier
manufacturer or grower
Description
comments on distinctive characteristics of the ingredient
Grouping
drop-down menu for you to indentify the type of grain/malt
DBFG
Dry Basis Fine Grind
this is a value which represents the maximum amount of yield which can be extracted, under laboratory conditions, from the grain
measured as a percentage of the weight of the grain
below 78% DBFG extract is considered substandard
DBCG
Dry Basis COARSE Grind
More closely approximates the typical crush achieved in breweries, and therefore gives a better indication than DBFG of the extract potential of the grain
FG-CG
Fine Grind Coarse Grind Difference
(DBFG - DBCG) ÷ DBFG
HWE
Hot Water Extract
AICG
As-Is Coarse Grind or Extract As Is
this is the extract yield including moisture content
Moisture
the amount of water that was present in the malt at time of analysis
Potential Extract
potential Original Gravity one pound in one gallon
HCU
color measured in degrees EBC or SRM (Lovibond)
Protein
TN
Total Nitrogen
TSN
Total Soluable Nitrogen
SNR
Soluable Nitrogen Ratio
DP
Diastatic Power
Cost/Unit
unit cost of the ingredient
