    These valves or possibly even a needle valve are all good choices. Smaller valve if you plan to blend with CLT, bigger if you want to blend with "regular" inlet temp water.

    They are generally...

    I have found Silicone seats to hold up no better than EPDM, and technically Silicone is less resistant to Peracetic. I think the durometer value or hardness of the material tends to matter more in...

    You've got the right idea. Trub out with a small diameter hose and do it often to save on volume, and clear out better. Crash cold and fast to aid floc. Condition as long as possible. Don't bother...

    By chance do you have any links to these studies? I am interested in learning a bit more about this since my experience seems to show the CaraPils/CaraFoam malts aids in foam retention, although I...

    This...Do you use oxygen or air? What rate? Also do you use yeast nutrients? Do you crop the harvest, or just collect all the yeast?

    Personally I would not pitch a yeast with 60% viability no...

    Yes it will work as long as you respect the pressure limits. I tend to prefer it in some locations due to the pliability of the hose.

    Yes you need a properly rated tank, as most tanks are rated for one bar working pressure. You need a tank rated for 2 bar to hold the appropriate pressures. You can then lightly carb the beer with...

    I would agree with most that Viton is a perfectly acceptable material for the majority of brewery uses, but would counter the common belief that EPDM is less resistant to PAA (and other commonly used...

    I don't think it is quite that simple.

    I doubt very much they have an exclusive contract that doesn't allow them to use other carriers. That would be a huge mistake for any company. In previous...

    I think, you missed that he switched from originally using a Wit to US-05. If both are giving him the DMS character it is most likely the oats. It is usually quite easy to tell the difference between...

    I think this is great information for sure, but I am not convinced it has that much impact on the longevity of beer life. Perhaps because my boils were not too vigorous, perhaps because three of the...

    Both those methods have worked well for me at multiple facilities. The key for me was to go slow.

    What issues are you experiencing?

    Are you seeing the same rate of evaporation in the beers? Roughly 6%+ per hour or 9%+ over 1.5 hours? Does the style in question contain a higher percentage of lightly kilned malts (Pils, 2 Row)?...

    I agree with WailingGuitar. Theoretically, but not so much in practice.

    We spund both ales and lagers at about 6*P with an average FG of around 2-3*P. Add some gas when needed. Have never had...
