Single unmalted grain wheat and rye - ideas???

[Quintus GenV]

So let's start with the grain. We grow wheat ourselves on the farm, and without our permission rye grows between the wheat. So those 2 grains are what I have to work with. I am not trying to make something using added sugar, and I don't malt the grains. So I use alpha and gluco amylase enzymes in a 100 liter pot, which I will heat with gas, load with 20kg grains and 60 liter water, which after cooking and seperating liquids from solids gives me around 50 liters at a gravity reading of 1.060-1.066 rather consistently, with the rye the yield is lower at around 1.054 using the same recipe. I don't really know if this yield is decent at all, I am just sort of getting these and rolling with it for now.

Fermenting is going well, FG of my wheat wash is around 0.098, and rye 1.02-04. I use wine yeasts, and currently trial-ling different yeasties, although my distilling prowess is probably holding back my wash's potential. I am seperating my spent grain from my liquids before fermentation, am I losing flavours I might want by doing that?

So up to know for the theoretical whisky, I am doing a stripping run, then loading my still with 60 liters at roughly 20% for my spirit run, all the different yeast batches started dripping at 81-84%, I tend to turn the reflux off when doing a spirit run, and (I charged my still with 100liters of 30% for the brandy, started coming of at 78-80%, and got my hearts between 65-70%, giving beautiful flavour.) My hearts for the grains are coming off at 74-76%, really harsh bites actually, without any real flavour. So I am a little stumped, although I know I am doing something wrong. Threw 100liters rye at 10% in the still this morning, came out at lower percentages, had my reflux spit it out between 60 and 65%, but not any real flavours coming through again.

I know that there is more flavour to be had, as my very first test batch of whisky I made, I had spitting out in the 60 range, with too much flavour actually, and now it just dissapeared, and I do not know what I am doing differently really. I can give more info, but don't really know what will be helpfull at this stage
