Regardless of all of this speculation by all the relevant 'experts' and product assasins - the invitation is always there for anyone concerned, to come along to one of our little brew days and witness the miracle of me circulating hot caustic solution/citric acid/phosporic acid sanitiser though this same hosing, and then do a brew with it - all with no taint. One happening this Sunday actually.
Simpy put, I won't be changing the hosing on my brewery any time soon, as I haven't been shown anything conclusive at all, and feel that everything mentioned is pure speculation, and drawing longshot conclusions based on VERY precarious logic - not FACT. FACT is what I can show with new piece after new piece after new piece of hose. Fact is that Foles was clearly having an issue with something to do with his brewing. Fact is that the issues stopped at the same time he replaced the hose. SPECULATION is saying that the hose was responsible or in fact had anything at all to do with it - FACT would be being able to prove it conclusively.
The same faults quoted "Phenolic - mouth coating" can also be very quickly attributed to infection which brings me to my next point - Foles is/has been using (and I quote - post 79) "I mentioned it in a previous post - sodium percarbonate (if my memory serves me correctly) and tap water. " to sanitise the hose. Sodium percarbonate is NOT a sanitiser. It is a cleaner. It is also not 'no rinse', and will taint a brew with an alkaline mouth coating contaminated taste if not VERY well rinsed of brewing equipment - and that is a FACT. It may also have nothing whatsoever to do with that. It may have something to do with atmosphere, airborne contamination from the shed roof or the neighbours trees or whatever.
It may be that there was an issue with this particular piece of hosing. It may also be just as likely that it has nothing to do with the hose at all (more likely based on the fact that I am using hosing cut from the same roll). It is also possible that the change in hosing has nothing at all to do with it, and Foles has just been lucky lately and very unlucky before. Who knows. Again, speculation.
Overall I am glad the issue seems to have gone away Foles. If I really thought there was an issue with the hose, it would be removed from sale - simple as that, but I believe that there are too many other possibile causes for it to have deserved to have been called into question in this fashion. Hope the issue doesn't surface again.
