    Sterilizing that head space

    the the Yes that would certainly sanitize it. But I'm thinking more about the complete removal of oxygen. The initial responders have got me curious about that.

    Sterilizing that head space

    One more question. Both of you are using gas to push through the entire liquid content of a keg. I'm not. I am just pouring starsan from my five gallon bucket, into the top of my serving keg , using gravity. My method uses much less gas. I just use gravity. Is there some advantage to...

    Sterilizing that head space

    Both are nice solutions, thx If you are filling the receiving keg from a designated supply keg, I imagine the supply keg would have to have a little bit more capacity than the receiving keg. Either a bigger keg, or prefill some starsan into the receiving keg before you start?

    Sterilizing that head space

    I"m sure many folk aleady do this, but today's discovery was fun, so thought I'd share. I've started sterilizing my small kegs by filling them with starsan and pushing it all through with co2. Using fermentation gas when I can, otherwise with bottle gas. But I know that when I fill the keg...

    Is there a way to remove a hop bong without exposing wort to air?

    Yeah, @Whisky River I agree. I could buy a second butterly valve. But I would also have to buy another corny lid that flares up to a TC fitting under it. I think I'll just stay the way I am. I just brew in series anyway, not in parallel. I brew around the first of the month and...

    Is there a way to remove a hop bong without exposing wort to air?

    Good morning all I have just started using a hop bong. Photo below. It appears that I have to keep the bottom half of the device attached to the keg, all the way through to the closed transfer. I pitch the yeast into my corny keg, attach the hop bong and close the butterfly valve. I can...

    When to dry hop

    Wild idea, that perhaps adding hop pellets at yeast pitch can DECREASE risk of infection. Adding hop pellets means you are adding a pile of anti-microbial agents, just at the time that the vulnerable wort needs protection the most.

    When to dry hop

    That point seems true. The idea that even at yeast pitch, the introduction of pellets doesn't seem to cause infection. While unsanitized items can cause infection. I have dry hopped at yeast pitch. I had no choice, as my hop bong was tied up with another batch. I'm now doing cold side...

    Refractometer and hydrometer not agreeing

    Sigh. Nothing is perfect. I can see why people just stick with a hydrometer. It does work and is simple. There was a post earlier about an easier to read hydrometer. That certainly is worry free. https://fhsteinbart.com/product/specific-gravity-range-precision-hydrometer-1000-1070-sg/

    When to dry hop

    Me too. It makes sense that if you want to take advantage of yeast biotransformation, and you own a hop bong, no point dry hopping at yeast pitch. For a couple days from pitch time there will be no benefit. And there is a risk of infection. IF you have a hop bong, better to wait a bit...

    Refractometer and hydrometer not agreeing

    Yes, it makes sense that in full krausen, yeast and foam and hop debris could pile onto the Pill and affect accuracy. But wouldn't this mainly be a problem only in mid fermentation, meaning full krausen, and not near the start or finish? Since it's the start and finish I care about, a mid...

    Refractometer and hydrometer not agreeing

    Thanks for that. My eyesight is fine but maybe I'll try that photograph tip.
  13. kohalajohn

    When to dry hop

    Yes, the best judge is yourself. I should try splitting a batch and in one, add hops at yeast pitch and in another add them later in full krausen. See if I can tell/prefer one over the other.

    Refractometer and hydrometer not agreeing

    FH Steinbert makes a much better hygrometer, I'm sure. But after shipping to Canada, it's actually cheaper to buy a Pill. I see it like bbq thermometers. In the old days I'd check the doneness of a roast from time to time. But the time I poked in the thermometer would be before or after...

    Refractometer and hydrometer not agreeing

    I don't think it's "very bad eyesight". Everyone says that, so that means they are just damn hard to read. You shouldn't have to take photos. That's a problem of the tool, not of you. The refractometer is easy to read, but is never accurate out of the box, and needs to be calibrated...

    How are You Measuring Fermentation Temperature?

    The car anology shows the issues with varous measurement systems. My 911 had temperature readouts for both water and for oil. When I started it up, the water temp would rise up fast. The oil temp would lag behind, and quite noticeably.

    If entering the world of the Pill would make my lfe more complicated, I don't want it. I'm not the guy who happily builds raspberry pi control modules and such like that.

    Refractometer and hydrometer not agreeing

    That is helpful, thanks. I'm with @bike2brew in that at my age, it is difficult to exactly see where the hydrometer is floating. And while all the subsequent info abut calibrating refractometers is helpful, it's a bit of a thing. You know, I always thought the kegland Pill tilt system was a...

    Pre fermentation. OG. Where would I find out more about "wort correction factor"

    Refractometer and hydrometer not agreeing

    So, my hydrometer says 1052 and my refractometer says 1048. I have been careful with my hydrometer readings. Spin the pipe, watch closely, ensure the surface tension is not messing up the view. And I have carefully calibrated my refractometer. Cleaning it, adding room temp water...
