Hi Grant,
I perfectly understand, I was diagnosed 5 years ago with Coeliac disease. I have 3 immediate family members in Oz also with the condition. Because of the different healthcare systems there are large differences in the way the condition is treated. For example once diagnosed in the UK you are kept under constant supervision by a gastrointrologist and dietitian. Initially reviewed 6 monthly and once stable annually, full sets of bloods etc. You are also able to access 1000's of gluten free 'staples' on prescription via your GP. Sadly beer is not considered to be a 'staple'
Back to the issue of sensitivity. Before the tightening of the international CODEX gluten standard (last year I think) I wasn't able to tolerate many so called Gluten free products, esp. the ones with CODEX wheat starch. Since the change I've been fine. This could be down to the new standard, but could also be down to other factors such as there seems to be a biological memory for other compounds associated with the offending proteins.
One significant difference seems to be the level of funding for good scientific research into the condition, recent research over here as found that many people with coeliac disease benefit from up to 50grms of GF Oats a day. Whilst I find this a bit much for me, I now use up to 10% GF oats in some beers. I have not had a problem with this. I don't know if GF oats are available in Oz.
As I said before, it's entirely down to what works for you.
CODEX standard is a international standard. Labeling laws are local although the EU of which UK is part, have unified labeling laws. 'Strict' may well just equate to 'we haven't done the research yet so lets be conservative in our approach'. For example I don't understand why the 65DE doesn't comply if it is entirely comprised of Sorghum.
Looking forward to having a go with this Briess stuff though, I might have to get some from the States though as it doesn't seem to be imported into the UK at the moment.
Hope you all had a good extra day off. Strangely no Queen's birthday here.
Cheers
Jay
