    Effect of boiling on pH of kettle soured Berlinner Weiss

    After further research I'm not going to even boil it, just bring it up to 170 for 10 min w/ 5 ibus of Saaz and call it good. The twang will be mild, but should please a bigger crowd. I'm planning on adding apricot puree to half (post- ferment) and WLP 670 to the other (pre-fermentation).

    Effect of boiling on pH of kettle soured Berlinner Weiss

    I'm attempting my first kettle sour Berliner Weisse using WLP 677. After 4 days my pH is sitting at 3.88. I'm looking for a final pH of 3.5 - 3.6. I'm planning on a 90 min. boil which should bring my volume from 15 gal. down to 12.0. Does anyone know how this will affect the pH? I'm...

    eBIAB Rye IPA scorched for the THIRD time!

    I'm feeling pretty confident that the the beta glucan from the rye created the gooey mess on the false bottom and the element. I'm also confident that the recirculation kept the element surface temp down which kept the goo from baking onto it. I also think moving the wort out of the bottom and...

    eBIAB Rye IPA scorched for the THIRD time!

    Here's an update for anyone interested. I went back to the original rye IPA recipe that resulted in my first scorched batch (including 1 lb of flaked rye-goin' full parameters!) I decided to do a separate protein rest with the rye in a smaller kettle at 122F for 20 min. I then added this to...

    eBIAB Rye IPA scorched for the THIRD time!

    Good point. I was thinking about that during the zd batch. I'll have to be more cautious this time around.

    eBIAB Rye IPA scorched for the THIRD time!

    OK, I was a little timid about rebrewing the same recipe right off the bat, so I went with a Zombie Dust clone. I heated my water to 157 and then mashed at 149. I then recirculated into the grain bag while raising the temp to 168 for mash out. I can see how the problem may have started with...

    eBIAB Rye IPA scorched for the THIRD time!

    The false bottom comes out when the bag comes out. I'm going to try it one more time w/ recirculation this coming weekend. I'm assuming it is a slow recirc. Details on that? When done mashing I will transfer to a second kettle for boil just to see the condition of the element. I'll report...

    eBIAB Rye IPA scorched for the THIRD time!

    Just checked out the perforated pizza pan I use to keep the element from melting the bag and it has a thick layer of light colored goo on the underside. Now I'm wondering if "stuff" is settling on the element during the mash that gets cooked when I mash out. But then why is it taking over an...

    eBIAB Rye IPA scorched for the THIRD time!

    I soak and scrub down the kettle and element w/hot PBW and recirculate 160 degree PBW through everything else for 20 min. The kettle starts very clean. I find no evidence of any leaks in my bag and when I empty my kettle there are no residual grains at the bottom. The element is fairly...

    eBIAB Rye IPA scorched for the THIRD time!

    No changes I can think of, other than doing the rest on the 2nd attempt. Mash pH was dead on 5.2 (w/ phosphoric). I use a perforated pizza pan to separate my bag from the element (learned the hard way). Curious why this is an issue w/ ebiab. I've done plenty of hefeweisens w/ 10# of wheat...

    eBIAB Rye IPA scorched for the THIRD time!

    I normally run 90-100% w/ no problems. I'm making 12 gallon batches. Perhaps ramping it down to 60-65% on the back half of the boil? I haven't notice the smell until after the first hour.

    eBIAB Rye IPA scorched for the THIRD time!

    Never had a scorched batch before with 50+ biab batches. Suddenly, well into the boil a burnt smell started. Tasted terrible. Had to pitch it. Element was a crusty and a pita to clean. Tried it again, following advice to do a 120 degree protein rest, mashed at 150, mashed out at 168 and...

    Wiring up my "new" walk-in

    Just found the 220v sticker on the compressor. So, that accounts for the red wire. Blue wire attaches to the coil on back of the compressor.

    Wiring up my "new" walk-in

    Here's a few pics. I don't know any electricians, and I have lots of brew to share so that may have to be my next project. On-line searching brings up nothing for the model # and the company still has a website, but I doubt they will offer wiring info to a customer. Can't hurt to try, so I...

    Wiring up my "new" walk-in

    Picked up a 6x6 walk-in from a retired florist and wanting to wire it up. Problem is there are five wires that need to be hooked up to my shop circuit. It is a 120v unit and the wires are as follows: Black - hot White - neutral Green - ground Red - ? Blue - ? The red runs to the coil...

    3bbl Electric Control Panel, power concerns.

    Thanks for the response. Are you running PIDs for your set up(single or two)? I built a control panel for my 10 gallon system with 1 PID and a switch to move from HLT to BK, but after building it I realized I could have just swapped plugs and utilized the auto/manual on the PID(which I have to...

    3bbl Electric Control Panel, power concerns.

    I would be very interested in seeing the final drawings for your set up as well. I am setting up a 2 1/2 bbl electric system, but am going to go with three 5,500w elements. in the hlt and bk. If I'm not doing back to back batches is there a way I could set up my panel with just three outputs...

    Contactors for e-brew heating elements.

    Also looking for 3 of these for my 5500w elements. Any more coming?

    Manifold pipe diameter?

    Hey, I'm in the process of designing a copper manifold for my mash/lauter tun. It is a 275 gallon dairy tank with a motorized stirrer. What I'd like to know is what size pipe would be recommended at this volume? I'll be sparging at ~2.8 gal/min. Should I use the same pipe size throughout or...

    Suggestions on 2 1/2 bbl e-build

    $200 a piece off craigslist. When I called on them one was already spoken for, but the guy never showed. They were pretty nasty, but have cleaned up very well.
