    Could also be some form of wild yeast - forgot that some of these also form a film (pellicle)

    You may get abnormal flavours (possibly acetic acid but depends on yeast type and conditions) and...

    In the UK, being temperate, there is no problem with outdoor fermenters with a bungalow working space below. HOWEVER, the breweries I have seen in Finland, where there are extremes of cold, rather...

    If you are meaning one of the ones without a pressurised tank above the filler tubes, then you are wasting your money - you won't be able to fill fully carbonated beer reliably.

    Agree with Tim's comment, BUT, in the experience of a few guys I know who have this facility, they dislike using it for a couple of reasons

    Firstly, the systems are not fitted with effective...

    If your system is big enough and correctly set up, it shouldn't matter where in the system you fit it as the header and return systems should have sufficient flow and pressure differential...

    If hot (ca. 65 deg C) formulated caustic at about 2% w/v doesn't work too well, add some hydrogen peroxide to the recirculating caustic. Unfortunately, I can't advise how much per litre / gallon...

    One brewery I worked at put ten batches into the same FV one after the other, over 20 hours, but with differing levels of oxygen - some at the end didn't get any - I can't remember the exact levels...

    Water at sparge temperatures will pick up negligible amounts of oxygen so tradition spray arms are not a problem. Any cold water addition to control the temperature will introduce more oxygen than...

    A four roll mill only really makes sense if it is fitted with sieves to separate out the parts you don't want to send through the second set of rollers. 2k doesn't sound anything like enough to...

    I think beating the living daylights out of the mash with one of those mixers would be a disaster, as already noted. Try a grist to liquor ratio of about 2.25 to 2.5 to 1. Stir just enough to wet...

    Small diameter brewery hose - flex-rite, purple snake or equivalent quality with manufacture supplied swaged ends. These will cope with PAA or steam, or 85 deg C hot water for sanitisation. I think...

    The pipe shown looks incredibly oversized (diameter) for a sparge arm. Is that really the sparge arm?

    Agree with the other comments, but you also need to change any remaining hoses to the same size - no more than one inch. 1.5 inch pipework and hoses are unhygienically large for anything...

    Not sure how you intended to clean the keg - presumably by taking the spear out. But that leaves two major problems - ensuring you have jetted every internal surface of the main keg shell, and...

    Looking at the video, the foam seems pretty consistent, BUT, I would be VERY concerned about oxygen pickup in beer since he is putting the ends on without undercover gassing / bubble breakers / inert...

    If you are only brewing 3 - 5 US brls, then hydrostatic pressure is irrelevant unless you want to deliberately ferment under pressure to help suppress esters. In which case I would ferment a degree...

    Funny you should ask that. A virtually identical question was raised on the brewery engineering forum on LinkedIn. So, hopefully, John Cluett, who wrote these responses, will not mind me copying...

    I second the use of a refractometer. Brix and plato are so close that for runoff purposes from the mash you might not even have to bother consulting one of the conversion charts until perhaps you...

    So the Murphys tablets are recommended at 1 tablet (1.75 grams) per 1400 litres which gives an SO2 content of 0.785ppm

    BSG tablets - 0.5 gram gives 30 ppm in 3.78 litres

    So if my brain isn't...

    The sulphury stench is infection growing on residual organic material left in the PHE. Simple as that. It needs cleaning properly. Start off back rinsing and then cleaning at 150%, or possibly...
