I have never ever commented when a brewstore owner made a moronic comment but here it.
1. I am not going into competition with anyone nor trying to make competition of any kind.
2. I am not going to mail anyone. It is for pickup. As a favour to brewers around me. I am getting the 125kg lot because it will be used for pets and garden. As mentioned, I am getting it for my chooks and guinea pigs so will be buying it anyway.
3. I am not going to vac bag. Waste of money. It doesn't go off, absorb moisture and will be opened constantly, in addition to never neing vac bagged in the first place so it would be useless.
4. There is no chemical residue to be concerned with.
5. It is not a profit making venture. It covers my costs only +/- a tad
6. I live in Melbourne so try getting it here for $1.50/kg. LHBS is more than a dollar and requires driving a considerable distance.
7. It is hardly a difficult endeavor to undercut the LHBS, irrespective of the reason for it. There are numerous products, such as rice hulls, that are ridiculously overpriced.
8. Your skill at cracking beer etc is not applicable to everyone. A bit of husk chucked in for less than a dollar a kg can make the day so much better for the average brewer.
9. I have someone buying 20kg already so it cannot be that bad a deal. It is cheaper than buying the common 15kg bags (they were priced from the suppliers at $16-18).......if you can be stuffed spending an hour driving to collect a bag...great time and $ saver.
See....not such a bad option.
Mate I retail a 5Kg bag for $5 so $1/Kg, that includes the time to weigh them out and a 35cent food grade barrier/vacuum bag; can land 4 bags anywhere from Port Macquarie to Wollongong for $10, call it (for 20Kg) $1.50/Kg delivered
If you want to go into competition with home brew shops you might have to sharpen the pencil a bit!
Mind you $7/Kg is a bit on the getting screwed side of the line and I can understand you amping up.
The "normal" rate is about 10% of grist, having said that personally I have never needed them even in a 100% wheat (made just to prove a point), it largely comes down to how well your grain is cracked, it is possible to reduce wheat to a very even nearly flour free kibble that will drain easily.
I do find Rice hulls can throw some flavour (sort of straw and some colour surprisingly enough straw colour) so soaking and rinsing them is a good idea, unless you are concerned about removing any chemical residue that might be on the hulls, just soak them in hot (80+oC) water, strain them out and stir them into the mash near the end.
