also, i've had my lacto buchneri on a starter plate at 100F for 4 days and I just took the tin foil off the top. It doesn't smell as sour as it did when I poured it in, just more like warm DME. Is this normal? I'm waiting for my ph meter to come in the mail since my strips only go down to 4.6 :(

If the pH has dropped below 4.6, you should be OK.  I don't get much of a smell from lacto.

Unless the starter smells bad and different than what the beer should smell like, I would pitch the entire starter so you don't have a long lag with the lacto and because dropping the pH of the beer quickly is particularly beneficial if you are pitching the lacto before the yeast.

I don't recall conversations regarding boil time, but I do remember conversations about copper eliminating onion flavor in beer.  I have some brass fittings in the brewery and have not noticed any onion in the one beer I made with Summit in a hop stand.

24 C (75 F) is a very high temperature for a lager yeast.

That was actually very helpful. I read all the sour and wild yeast chapters in "Home Brew Beyond the Basics" and several posts in here but sometimes you just have to ask a direct question to find the answer quicker.

-I didn't know lacto didn't create a krausen
-My ph strips only go down to 4.6 (and hard to read anyway) so I ordered a ph meter last night that goes from 0-14, hopefully that helps
-I read lacto was sensitive to IBUs so i'll find out how much I want to add and boil if necessary.

The other option beside waiting for lacto fermentation to be done, then pitch ale yeast (boiling in between if necessary), would be to create 2 worts with 2 different yeasts and mix at the end. I will contemplate the benefits of both while I await the ph meter and wait for the lacto starter to be done.

thanks again!

Just a few followups,
-5336 does not create a krausen.  Many other lactos can.
-Lacto is sensitive to IBUs, but if you boil after the lacto fermentation you can add hops to your heart's delight
-Boiling loses some of the wheat character.

While I can't speak to the 5335 in particular, it is pretty unlikely that the lacto would be dead.  120* is at or near the upper range of their activity range.  The lacto maybe "stunned"  and may take a while to get back going, but ....

Lacto 5335 does not generate CO2 so you won't see a krausen.  You can monitor the fermentation by monitoring pH.  Lacto 5335 only eats glucose IIRC so measuring gravity is not a particularly useful way to measure progress.

You say "aerate again" which suggests to me that you aerated before pitching 5335.  If so that was a mistake but you should be OK ultimately.

Boiling is optional.  Once the pH is below 4.5, there is little or nothing that can hurt you in the wort, but I wouldn't drink it until the ale yeast has finished fermentation .  If you want to develop IBUs then boiling or near boiling is necessary. 

I can't spare more time today to talk you through this.... google sour worting for more info.  Mad Fermentationist is probably a good source of info.  There may be some threads here about berliner weiss that you may find useful.  Good luck!

Pimp My System / Re: Automatic beer bottling system DIY

My thought for improving system would be to put a valve in the bottom of the roaster pan or to use a valved pot so that it wouldn't be necessary to have any siphons.

I wonder if there are any pressure regulators that are easily cleaned and sanitized, cheap and could be used instead of the roaster pan and auto-sparge to set the fill level.

Guillaume, could you post some pictures showing the roaster pan with all the connections made but without the lid, preferably with liquid flowing through the pan, please.

The website says there are issues with the app that are being investigated or corrected.

You will hit all the hotspot enzyme temperatures doing that.  I've done it.  I believe you will get a different beer than just mashing in the 150s right away.  The beer will generally tend to be thinner / more watery, more fermentable, and possibly more crystal clear with a slow rise mash like that as compared to a single infusion in the 150s.  Please feel free to run this as an experiment where you do two batches with the same grist to see what the differences are for yourself, and share results with us all if you do, that would be awesome.

+1.  There are various rests below 150* including phytase, glucan rest, protein rests, and a beta-amylase rest.  These rests are generally not beneficial or necessary for modern malts.

Worthless. What happened to wearing a f*cking bag on your back? Less chance of it getting all shaken up also. That's just me, people can spend their money on whatever worthless crap they want. As a cyclist who rides for transportation, this makes no sense to me, and just seems like a hipster/trendy thing that is way over priced. Kinda like the fat bikes you see nowadays...

The growler hangs underneath the saddle such that a rider could only sit on the nose of the saddle and pedal.  Hope the rider isn't going far.

Since my initial post, I won first prize in Spooky Brew for worse beer.  I won a can of old malt with bulging ends.

I did add Brett to my vomit beer.  For a while there was a great pineapple odor, but now it smells and tastes of parmesan cheese. When I need the carboy, I'll dump it.

A lot better than brewing over a urinal.

I use Kai's model for stir plates.
