I created a yeast starter with Wyeast 3724.
I brewed a Saison and tried pressure fermenting at 90F = 32C with a spunding valve set at 10psi; big mistake.
Wyeast recommend fermenting at this temperature.
It started out OK but then went for a week and 2 days of no fermentation and developed a horrible taste.
Then I learned Wyeast 3724 does not like Pressure.
So I transferred the 2 corny kegs to 2 fermentation buckets i.e. no pressure
Kept the temperature at 90F = 32C controlled with a STC1000 but...

Hello, Phillip321.

I see that you have a number of questions here. The bad taste is (to me) the most important - the complex equipment you describe here and in other posts is far beyond my experience in BIAB brewing: kettle, bag, hopsack, bucket, wide-mouth glass carboy, gravity transfer hoses followed by bottles. Temperature is measured and crudely controlled, but mostly ambient after pitching. 100+ batches experience, none tossed, so far.

Wyeast 3724 is found here (the source) and an...

After about a year and a half something strange has begun with my Inkbird ITC-308. It seems that as the set temperature is lowered the probe reading drifts further from the actual temperature. I have a digital thermometer that I calibrated in both ice water and boiling, accounting for elevation and barometric pressure, and it comfirmed the issue over multiple days. I get that the 308 isn't too expensive and easily replaceable but I was just wondering if anyone else has experienced this? Also,...

I had something happen that some of you may find interesting...

Yeast Starter:
After fermentation I normally save sloppy slurry of the yeast, and if it's within a few months will repitch it in a yeast starter, then into my wort to make new beer. Someone from my homebrew get-together group had suggested, if making a bigger brew, put the bag into a smaller brew kettle after pulling it out of my main brew kettle, add some water and make more starter ... Normally have to boil it for a while to...

Thank you, Scott.
That seems to be the best answer involving flavor leftovers for this thread.
Storage of that remaining starter under wort/beer or washed is another choice discussed at that link. When preparing for the next brew, make another large starter and subdivide again. Repeat as desired. 12 generations is quite a lot, but as long as it works....
I think your homebrew group's advisor/sage may have also demonstrated how hops can suppress growth of undesired bugs, but then his starter...

Adding LME or DME to fermenter??

First post by Christin, 7 years ago

Hello this is my third batch of beer and i missed my OG by quite a bit. My target OG was 1.046 and i only achieved 1.032. I think i may have missed my target because i milled my own grain this time around. I was wondering would it be too late to add DME or LME after three days of fermenting??(my yeast was US-05) Or do you think i should leave it alone??

Looking for some guidance!

I'm a new BIAB brewer, having done some extract brewing over 20 years ago. I'm on my 3rd BIAB batch and things were going well for the first 2 days after I placed it in the fermenter. But then I was away for 2 days and came back to find the stopper and airlock had blown off and krausen on the side of the bottle (lesson learned, should have used a blow-off tube). I'm not sure how long it was like this: could have been an hour or two, but maybe up to 2 days. I cleaned...

Fast ferment test and a PP trick

First post by Mad_Scientist, 7 years ago

Recently I picked up on something new I have never done until now . I got interested in the low oxygen brewing website and picked up another (cold side tip).

Ever since I have been pressure fermenting I have been just letting it ferment all the way it would go, then at FG do the closed transfer to a serving keg thing. I lost my last double batch (yes all 10 gallons) when air was sucked in due to worn out corny keg post o-rings. So to never repeat that again, it's advised to transfer when...

Process Tweaks and Aeration

I have gotten almost all my process stuff from different posts on this board, the biabacus has been awesome and every time I think I'll tweak it I realize that it is right and I am wrong and I should have just done what it suggested. I'm pretty happy with my beers so far -- 4 of them total, all of them electric, biab, no chill. What I was hoping you guys could do is look at my process and see if there are things I could tweak out. My specific question is about aeration. I wouldn't say I'm lazy...

FFL,

Your step #7, I would leave your container out for 12-24 hours to cool down to ambient temp before putting it in the fridge. That is a big load on the fridge I would think.

This is a complicated scenario.
Yes there will be a large total BTU load to cool it, how that load is spread out (how long it will take) depends on the mass percentage it represents to already chilled mass in the unit.
So the load being spread out longer by being less of a total mass makes the load not as large for...

Hello i am new to the world of brewing and I recently bought ingredients to clone my favorite brew (Barking Squirrel Lager). Being a newbie i never realized how cold lagers have to ferment. My question is how warm can saflager w34/70 yeast ferment. The coldest spot in my house is in my crawlspace (cement floor) 17C or 62.6F(spring). Do you think this would be cold enough? Also the recipe calls for 7days primary and 30 days secondary would this change with the warmer temps? My plan was to keep...

The fermentis website has a datasheet for each yeast that offers fermentation ranges. For 34/70 they say fermentation temperature: 9-22°C (48.2-71.6°F) ideally 12-15°C (53.6-59°F) .

Hi, I know this was discussed in this post

But that was 4 years ago, I was wondering if anyone had looked into it since then.

Too much sediment?

First post by Ben85, 8 years ago

First post

Hi all
I did my first biab last Friday, using no chill to cool and started fermentation on Saturday night. Looking at the fermenter today and there seems to be a huge amount of cloudiness/sediment at the bottom. It's not overly visible on the picture, but it goes up just past the 5ltr mark and covers the tap. Is this normal at this stage of fermentation? Will it settle down or do i need to transfer to a secondary fermenter and try to lose of the sediment?

Did you transfer everything from the kettle or did you rack the wort off of the sediment in the kettle?

Air temp vs liquor temp

Bought a fermentation fridge and hooked up with temperature controller and heat belt (fridge is off for winter). Thermometer is taped to fermenter with polystyrene over it to try and measure temperature of liquor rather than air around it in the fridge.

Hello everyone, I've found this on secondary while I transferring to my bottling bucket.

Notice the white spots on the krausen collar and the little oil stains on beer.

I tasted the beer 3 days prior to bottling and it tasted and smelled great.

For the record, this batch of IPA had 100 grams of pellet hops used in dry hopping for about 10 days.

Should I worry?

About 6 months back I did 2 BIABs and a kit. The BIAB's were no chilled in cubes and the kit was pitched straight away in a regular plastic fermented. A few weeks later I pitched the BIAB's in the cubes with the caps on then backed off slightly.

The brews were in a humid room with a clothes dryer that gets used semi-frequently. Temps over the time have probably ranged from 15c to 35c.

The kit in the fermenter was tossed as it formed a layer of mould on top. I had it covered with plastic...

Todd,
That would be a good idea except someone might intercept this communication and use it in court...I'm thinking manslaughter at a minimum :)

On the positive side I believe botulism will do the job regardless of the quantity ingested. And I'm still going. I think 72 hours is the telling time, though.

I'm still so surprised that the samples tasted so good. I guess the co2 protective layer, the hops and the yeast doing their thing kept everything (apparently) okey dokey.

Hello,

I will do a 3 gallon batch of Hefeweizen for my next brew and I wonder if I can pitch the whole Wyeast 3068 pack without making a starter? According to their webpage, the Activator yeasts are designed to be used without any starter for beers under 60 OG (mine is 48) for 5 gallon batches, so I am afraid that I will overpitch. However according to mr malty I should be OK.

What do you think? Maybe I should not use the Activator nutrient?

If using half the vial, can I save the rest in the...

Transfering wort to fermenter : with or without trub ?

• 1

First post by clamsy, 10 years ago

First post

Hi all,

After my first home brewing day Friday, here is my first post on biabrewer.info :)

I've made a search on the forum and couldn't find any post comparing the two methods : some biab brewers transfer all the wort to the fermenter, with the trub, others rack it and try to leave all the trub in the pot, and I think some people transfer all the wort through the bag or some other filter.

So what are the pros and cons of keeping the trub ? Is there a risk of having off-flavours ?

Last post

---

You would maybe recover some wort from the hops but I would be surprised if it had any noticeable difference on the flavour, aroma or bitterness of a beer.

My understanding is that most of the volatiles are absorbed into the wort fairly quickly so squeezing wouldn't increase this.

And while efficiency is good it isn't the most important element of brewing. Being able to predict your efficiency for a particular grain bill helps you brew what you set out to but in terms of cost you might be...

ShorePoints, I use 68F for the 2.0 Volumes needed for my Ales, then after 10 days the Bottles go to 50F-55F for Drinking.

Hi!

For my first brew I ended up with a gravity reading of 1.018 after one week of fermentation, and when I checked again after two weeks it was still 1.018. Since I was doing a small batch I only added half of yeast package (I made 10 liters). The beer had an OG of 1.052 and the yeast I used was Mangroove Jack's M79. It's worth mentioning that I didn't re-hydrate the yeast before I pitched it and it stopped bubbling after 3 days. Also the temperature fluctuated in the room, maybe in the...

Transfer via funnel?

First post

I used to ferment in a plastic bucket but for awhile I have preferred a glass carboy. I have used a funnel to transfer the cooled wort from the brew pot to the carboy and I pass it through a mesh strainer to catch some of the trub.

I have seen a lot of people talk about using a siphon to transfer the wort. I have heard about risks from aerating wort that is still too warm but are there other issues I should be concerned about?

I should note that my beers have had good flavor and I haven't...

Yep, the Silicon Hose is great, just use gloves to control it.

Hot Side Aeration is a Myth!, You will collect MUCH more air into Hot Wort than Cold(which is what we need).

The time it takes for the Wort to Cool, will not Oxidize the wort, Unless you cooling over 2 weeks, and continuously bubbling air into the Wort.

The wort did ferment a day after cranking up the temperature and it stopped at 1.02. I've dry hopped it and am hoping to get it out of the fermenter this week to make room for something new.
