    Zip code is 54601, in La Crosse, WI. I'm willing to travel anywhere within a 200 mile (day trip, basically) radius to meet if you can't come to me.

    Wisconsin 15 Gallon Stout Kettles HERMS single tier system

    I'm downsizing my brewing setup to focus more on microbiology research and am looking to sell my barely used 15 gallon tri-clamp system from Stout Kettles. The system was only used a handful of times before I got a job as a professional brewer and stopped having time to brew at home. There's no...

    Wisconsin 2 Inline Stainless Chugger Pumps : $100 each

    These items have been Sold If anyone is in the market for an inline stainless chugger pump or two I have two like-new units posted to ebay. These pumps have only been used a handful of times and were disassembled, cleaned, inspected, and reassembled before being put into storage. All seals and...

    Slanting yeast

    Standard antibiotics can be used, provided you can legally acquire them, to inhibit bacterial contamination without otherwise inhibiting the desired yeast. With proper aseptic transfer techniques they're not necessary, but if you have the resources to use them there's no reason you couldn't.

    Delayed fermentation question

    Yes, and yes. You're likely thermal shocking your yeast and killing enough off to delay your fermentation. Do you, by chance, notice any slight savory or meaty flavor in your beer if you age them a couple months? You always want to try and have your slurry or starter at the same temperature...

    Yeast Left in White Labs New packaging

    That has nothing to do with transfer contamination, which is the issue of impact when discussing multiple retransfers to capture 100% of available yeast as was recommended.

    Yeast Left in White Labs New packaging

    Your containers may be sanitary, but is your breath or the air you're surrounded by? Is there any dust in the air to get into those vessels or that liquid stream? Are you positive that there are no mold spores anywhere nearby? All it takes is one errant spec of dust, spore, or breath droplet to...

    Is 5.4 to 5.6 too high a target pH? Questions...

    It's worth noting that the American Society of Brewing Chemists (ASBC), the standards body for pretty much all brewing-related testing, states that all pH measurements must be done at room temperature (RT), and all pH values given in any paper submitted to them must be RT values unless otherwise...

    Yeast Left in White Labs New packaging

    Unless you're doing this aseptically that's as sure fire a way to get an infected starter as I can imagine. The little bit of yeast that remains in the pack isn't worth trying to get if doing so causes an infected batch.

    Wisconsin 15 Gallon Stout Kettles HERMS single tier system

    The sparge arm, as it's set up, could potentially clog since there's no exit path other than the drilled sparging holes. Given the easy of swapping out tri-clamp fittings during the recirculation and sparging processes I find it's easier to swap between the sparge arm and a 90* elbow/tubing...

    Too late to oxygenate?

    The manufacturer claims that there is a a high enough sterol level in the cells they produce and dry to make additional aeration/oxygenation during the first use batch unnecessary. I'm sure they have data to support this view but, as a microbiologist, I find that claim suspect. Those sterols...

    How many yeast cells do I have?

    Overpitching can lead to a depressed ester production rate. If you're brewing a clean beer that's not a bad thing, but if you're brewing something like a Belgian that relies on yeast esters as a core flavor component it can definitely be picked out. The beer would, very likely, end up tasting...

    Is 5.4 to 5.6 too high a target pH? Questions...

    This is absolutely true. Most professional grade (not to mention consumer grade) pH meters are most accurate, even with ATC, at roughly room temperature. Not crash cooling your sample down to room temperature before testing it is simply bad protocol, and I'm surprised to see anyone advocating...

    Magnesium additions in yeast propagation

    mabrungard is right, it's best to keep your Mg^2+ ion levels below the 30-40 ppm flavor threshold since the yeast only really needs 10-20 ppm anyway. Any higher than that and you'll notice a distinctively unpleasant chalky tartness, and if you go too high (125+ ppm) you'll basically be making...

    Calculated Yeast Count vs. mL slurry from starter

    True enough. I tend to get into the gritty technical side of things when brewing due to my microbio degree and old career in the industry, but that's definitely overkill for 99% of homebrewers. Though, now that you mention it, I wouldn't be surprised if my old microbiology major advisor had a...

    Wisconsin 15 Gallon Stout Kettles HERMS single tier system

    Edit: Thank you to everyone who has expressed an interest in the various components of the system I posted for sale. Now that the stand has sold I will be parting out the system. Once this post ages out of the front page I will post a new ad for the individual kettles, pumps, and valves.

    Calculated Yeast Count vs. mL slurry from starter

    There's no need to get snippy. The protocol stated in the OP was for the starter, not for how they determined yeast cell count. If you don't have a protocol in place to confirm your own cell counts in your starter you're relying on estimations only, and all you'll ever get is a guess...
