    I've unsubscribed from everything but still get the daily SPAM. I guess I'll have to cancel my membership.

    Gout & Filtering Beer

    Ignoring the ad hominem: please explain in plain English how a change in hydrostatic pressure of the order of 10% can materially affect the solubility of a solid.

    Gout & Filtering Beer

    That is badly misguided. As Goatchop said above, gout is caused by the retention of purine breakdown products. In normal function the kidneys excrete the uric acid via the glomeruli but then some of it is reabsorbed. Gout is associated with a dysfunction of these reabsorbtion mechanisms. Uric...

    KegKing now at keg-king.com.au

    Probably worth referring that to Ebay. As an organisation, Ebay is very heavily buyer focussed (natch), they would probably be interested in something that explicitly threatens the utility of the feedback mechanism.

    EOI - Stainless 50gal drums

    I might also be interested for work. Ask your boss if he'll trade for wine. BTW melaleuca oil is mostly terpenes so it isn't difficult to wash out. Terpenes are insoluble in water but highly soluble in ethanol, so rinsing a couple of times with metho should see you good to go.

    Sodium metabisulfite question

    Yes. It's a standard analysis in the wine industry to heat a sample for 15 minutes after the free SO2 is measured to drive out all the bound SO2. That part which has oxidised to sulphate will remain but there will be no SO2. It probably wouldn't matter anyway, many brewing yeast produce SO2...

    Sparging question

    It should come as no surprise to find that the "least significant digits of the SG" has a name in German: it's degrees Oechsle, so an SG of 1018 is 18 oOe. Only ever seen it used by German winemakers. Yes, oOe/4 = oP is a good rough conversion up to about 15 oP. If you are good at mental...

    Sparging question

    At almost 5 oP you aren't going to be getting a lot of leaching, so pressing won't hurt and will make up for some of the lost extract. With a well designed brewhouse your last runnings should be about 2 oP and leaching does become a problem. I think this is due to a combination of osmotic...

    What strength are your final runnings?

    Wanted ; double or single wine barrel rack .

    We use metal ones to make stacking and moving barrels with a forklift easier. If you aren't moving the barrels often or you don't have a forklift you can make do with old fashioned stillage, which is very easy to construct at home. To hold two barriques you need two pieces of sleeper about...

    Sour beers

    Not necessarily an infection: hibiscus flower is very acidic by itself. I once developed a hibsicus flavoured wine as a contract job and was surprised by how much acidity the hibiscus contributed. It would be even more evident in beer with its higher pH.

    Just how DO you get that juicy IPA taste and aroma?

    True that. I happen to be doing some work on this for another application (ullaged wine tanks) and the speed at which oxygen diffuses through an inert gas "blanket" is surprisingly high. Even if you could get your "blanket" to be a metre thick it will be effective for about an hour. There's a...

    How Much Did You Brew In 2017

    I just re save each recipe every time it is used and add a sequence number. Don't forget to change the date, otherwise Beersmith defaults to the date of the previous iteration. To avoid clutter, I have folders for recipes so I can archive them once gone.

    Article on rain water tank safety

    Possums apparently. Mum is 93, lives by herself and has to be careful because her immune system isn't what it was.
