    NEIPA recipe thoughts?

    I think the most important question now is: What yeast? Similarly, one of the trademarks of a NEIPA is juiciness, and I don't think you have a the right hopbill for this style I would not dryhop with simcoe and would replace with El Dorado or Mighty Axe Julius (to the tune of about 1.5 ounces...

    I have spread zero false information and please do not call me a liar. That is markedly impolite. No one said anything about recurrent contamination. It isn't an infection, so it doesn't belong in this thread. As far as sources: As a former university lecturer of physics, I have access to...

    I guess we didn't beat the dead horse so we shall continue. the FLO11 gene is proven to be responsible for biofilm production. That said, FLO11 is present in Saccharomyces cerevisiae var. diastaticus and OYL033 Jovaru Lithuanian Farmhouse contains the STA1 gene that makes it a Saccharomyces...

    I think it would be helpful to all of us if you could post a picture or two. From how it sounds, we are all in agreement that what you have going on is normal. Quick questions: When did you bottle? How long has it been under refrigeration? What was your final gravity before priming? What style...

    while this has been fun and all in the name of actual science...I believe it should end here. That said: you have been provided a lot of information on biofilm and pellicle, as well as some classifications that you may not have known before. All in a good days work. it is my intent to encourage...

    so it was easy to find without doing any research that WLP700 for mead and cider (but often used in port wine beer) creates a biofilm. Now I’m not saying that my pellicle was not from the yeast, I’m just giving you a quick example with very little research of a S. Cerevisiae strain of brewers...

    Edit...near impossible unless you have a fruit orchard nearby, but then you wouldn’t be introducing a strain of Brett that produces acetic acid would you?

    I know you have a hard-on to belittle people and claim superiority, but it took me all of two seconds to locate a scientific journal that cites typical ale yeast (S. cerevisiae) producing biofilm https://academic.oup.com/femspd/article/65/2/169/681089 I suppose I will go further: It certainly...

    you are confusing my comment as to say that a pellicle didn’t form. These biofilms are always considered “pellicle” as a pellicle is simply a biofilm that forms at the liquid-air interface. Point being, the microorganisms in “brewers yeast” can form biofilms at the liquid-air interface without...

    interestingly enough, a biofilm atop wort can be comprised of many different things and is by no means automatically indicative of wild bacteria or yeast. It could be dead yeast cells, proteins, lipids, sugars, or combinations of all. *this is not my verbiage and is from a PhD in microbiology

    Update: day two of the film and I am confident it was acetobacter. Very strong vinegar smell in the headspace. Racked from under, picked up a bit of yeast from the bottom, left one gallon, primed, and prepared for bottle. Gravity was near terminal for a NEIPA. Tasted, smelled and tested pH prior...

    the hop bill left a ton of sediment under my beer in the primary that I just didn’t want there...but understood

    it’s actually a bad picture unfortunately. The white dots are actually from the flash and appear to be nucleation sites. Removed the 2nd hop bag yesterday and it looks like this today. on this batch, I had to rack because o had to get the beer off of the hops from boil, hop stand and...

    The surface of my NEIPA. It’s been dry hopped twice with 5.5 ounces total in the secondary. Find it hard to believe it’s infected. thoughts? by the way: smells like orange juice, looks like fresh grapefruit juice...getting ready to bottle anyway

    New hop varieties

    I harvested around 7 pounds wet last year, this year in late February I already had around 30-50 shoots starting to emerge. that said, I brewed two beers with my Petoskey from year one harvest...a roasted hatch chile session IPA that performed extremely well at competition and the same base IPA...

    Early season shoot woes

    But you did absolutely nothing to actually address my question. I appreciate the information, but let’s be realistic: I was asking if I should have any concerns about weather between now and the start of the growing season, not “oh no, I don’t know what to do with the shoots I’m already going to...

    My Hop Is Dying?

    The fact that nobody pointed out how much mold is on his coconut coir and how wet it is, is more troubling than anyone commenting on the plant. These plants are severely over-watered

    Early season shoot woes

    I just cleared my hopyard and realized that all 13 plants 2nd year plants have TONS of shoots thanks to our weather in West Virginia (extreme Eastern WV grow zone 6). I have some plants with 20-40 shoots...which seems insane to me. Any recommendations on what to do between now and a nice healthy...

    $900 for a hop trellis + 6 plants?

    The system really is legit. Its overpriced but good technology. I recommend building a similar setup with 4 6x6's and four 1/2 inch metal plates. You can drill holes in the plates and in the wood and make a similar rotating system. The benefit of the Ibex is that they send you all of the...

    Burner for 30 gallon kettles

    I am trying to find an adequate propane burner for my 30 gallon vessels. one is edelmetall and is 19.7" in diameter, the other is spike and is also 19.7" only one caveat, it must be standalone, tabletop style for my setup. any help would be awesome!
