infection

Hey folks, I'm brewing a Kolsch-style beer and added some orange zest and coriander to the secondary two days ago. simple question – is this appearance anything to be concerned of? And if so, is there something I can do about it now to mitigate any contamination or off flavors? I'll add a bunch...

At least two batches taste great at bottling day and develop "off flavours" after 2 week of bottle conditioning. I brewed pinapple ipa and raspberry philly sour. All tasted great from the FV. Added fruit in the end of fermentation. At bottling day both tasted fine. After 5 days in bottles i...

I have been homebrewing beer and cider for nearly 20 years without issue. Two years ago I got a little lackadaisical with a batch of cider and let the water evaporate out of the airlock. Once I realized it the cider had already turned into a nice batch of apple cider vinegar. I kept a small...

Today i noticed that some small stuff is floating inside and on my cider, is my cider contaminated?

Hi, I’ve recently started trying to home brew again ( with no success previously). I added the hops after 7 days the other day and found the walls of the fermenter to have some “dirt” on them higher than the beer level. The beer was never this high in the fermenter, it’s only 18L in a 23L...

I am a new brewer and I have finished three beers and have a fourth in primary fermentation now. All of them tasted great before I bottled and primed, but when I open them two weeks later they’re mostly flat and sour. After the first one I figured I wasn’t sanitizing carefully enough so I...

Thought I would try my hand at collecting some wild yeast from a pear off of my pear tree. Am completely new to this and to wild yeast...now am going to be "that guy" do I have an infection or is this a type of lacto that I collected? I dont smell anything funky or off, it smells tart and citrus...

So I brewed a lager about 3 weeks ago 3lb Pale 3lb Pilsner 3lb Flaked Rice Mashed at 152 for 60 minutes, then boiled for 60 minutes Typical hop additions Wyeast 2124 Bohemian Lager Yeast (1 pack) I made a 1L starter the night before, 18 hours before pitching. Went to transfer to a keg...

Beginner here on my 3rd batch. It is a Single Hop IPA kit from Craft A Brew. My OG was 1.063 and FG=1.010. Fermented 2 weeks at 68°F in a plastic Nortbern Brewer bucket w/ airlock. I never opened lid until kegging day. A. Is this a pellicle? B. I will not be brewing any sour beers, so...

Can someone help me identify the mystery substance I found in my fermenter? I was kegging a batch of stout and saw white substance in the fill line, when I opened the fermenter (after the fill) I saw the white substance pictured. Where it was adhered to the fermenter wall it was fairly thin (a...

I just transferred 6 gal to a bottling bucket and I see some white clumps floating. This is a brewers best pear cider kit. It’s been fermenting 2 weeks and looks a little like a tiny jellyfish. It tastes ok so far. Is it safe to bottle as is? Or do I need to put in some metabisulfate and keg it?

I had a buddy over and we made a batch. He's a blabbermouth so I was distracted and forgot to sanitize the kettle spigot before transferring to fermemter. I keep kettle very clean and normally run PBW through spigot after each brew. How worried should I be about infection?

Hey all, Last Sunday I brewed a pretty straightforward blonde for a family vacation in a couple of weeks. Recipe: 8 lbs Pale Malt (2 Row) US (2.0 SRM) Grain 6 82.1 % 0.63 gal 12.0 oz Cara-Pils/Dextrine (2.0 SRM) Grain 7 7.7 % 0.06 gal 8.0 oz Caramel/Crystal Malt - 10L (10.0 SRM) Grain 8...

Hey 👋 so I brewed a batch about 10 days ago and fermentation kicked off super quick. The krausen has been intense and I is a lot of true from Irish moss. The krausen was super sticky looking and started to drop 4 ish days ago. Thereis this lingering bubbly stuff on the top - I’ve given it a...

Any input welcome. This is my third batch (Tripel). No problems with the first two. But this is the first time I used some swing top bottles for part of the batch, and one of them has some very nasty looking stringy floaters traveling up and down (riding a bubble up, then dropping back down)...

I don't remember from years ago when I did my other couple of batches but I don't think I've seen this sort of stuff on the top of the beer. I racked to a secondary after 13 days. I used a carb cap, stainless cane and one of those 'sterile' filters to blow in after rinsing with bourbon and...

Okay, Community, here goes. The last two batches I have made (1 lager, 1 APA) both have come down with the same off flavor. Dull, cardboardey, faintly metallic, essentially nasty. Lagering does not help. I poured the lager into the garden after almost 6 weeks of no change, but the APA is new...

Hello Fellow Brewers! As a starter, I'm still fairly new to the brewing ins and outs as this is something I've picked up during quarantine. My buddy and I have brewed about 70 gallons+ of beer since late July, with many successes! On our most recent batch, I've noticed some particulates in the...

Hello everyone, It is my first time all-grain attempt and I think my beer is infected by lactobacillus. What is your opinion? and should I dump it or is there any possibility to get a good taste by any luck?

Hello, i recently started fermenting a brown ale and after the 8th day i took a sample using the tap on my fermenting bucket to see the specific gravity. Along with the beer a small amount of what looked like gelatinous fluff also poured into the cup, its hard to explain what this looked like...
