I would spirit run too.
You cannot win if you do not play..

Your persistent haze is from fusel oils, that came across because you collected longer than you should have. The collection probably looked OK, but when you added water to lower the ABV%, it turned cloudy.

This situation has confused many a distiller, including many on this site. It has also been asked and answered many a time on this site @EasyD.

It may not come out the best, but add plenty of water and rerun. Look at Anavrin's posted charts under "Cachaca Rum"/Recipes and get an understanding how toward the end of a run it can all go pearshaped very quickly as temp climbs and quality drops.

I accept that it may be fusel oils, but I haven't added any water..

I'm pushing a spirit run through now just to see what happens - foreshots were clear and heads are too. I'll update this post over the next couple of hours.

Update 1

3 x 100ml jars of potential heads
500ml taken as hearts
3 x 100ml jars of hearts / tails for cuts - currently down to 55% ABV

no perceptible haze in any of the above

Update 2

3 x 100ml jars additional to the above, last jar down to 30% ABV.

The second to last jar has a perceptible haze in it, and the last is clearly discoloured.

Conclusion

An interesting experiment - I'll let it all air overnight and make careful cuts tomorrow.

This was a lot of work and worry for not a great yield, and I have to say that IMHO Mash's Wonderful Wheat Wash is several steps above FFV. I have enough wheat bran left to have another go at some point, but I think my next recipe will be the dreaded kale!

Cheers, and thanks for all the advice
