What kind of contamination is this and is the beer ruined?

This is my first all-grain batch and unfortunately it has developed some kind of growth. It didn't smell like death, actually smelled pretty good, and the samples I have been taking have all tasted good, so I went ahead and bottled it. Just curious what it could be and if I will be looking at a loss with this one.

Half the amount of dry spray malt added to a kit

I have just realised that I have only added half of the required amount of spray malt to my beer kit on day 7 of fermentation. Can I just stir in another bag of spray malt after racking it off the yeast cake and continue to brew it in the beer bucket with airlock. Would I still add sugar again before putting it into the pressure barrel.

Can I add more yeast during primary fermentation?

I've got a brew that's been on primary fermentation for 10 days and still haven't seen any activity in the airlock (again). Gravity has dropped from 1.040 to 1.014, but I'd still like to raise the alcohol content a little and am worried the beer will come out flat (much like my previous attempt). I believe the problem is that it's too damn hot here and the yeast have been killed off, despite keeping the fermenter under an aircon vent …

I have Youngs Elderberry kit

I am on day 3 and instructions state "top up 4.54 litres tepid water". Does this mean top up TO 4.54 litres? Should I leave space in the demijohn and how much space? It's still got 7 to 20 days to ferment yet! Terrible instructions as very vague and badly worded. Thanks JY Newbie! I did that and it bubbled up into the airlock! I had to take some liquid out again! Maybe I've just got a lively must going! …

Best way to avoid stirring up trub while bottling/kegging from the primary?

Since I started brewing I've ALWAYS transferred to a secondary after about 2 weeks. This was how I learned and what many recipes say to do so I always did it. And I felt that this was a fantastic way to really remove that yeast cake and trub at the bottom out of your fermenter, ultimately providing less of a risk to stir it up and have it in your bottles or keg. Many discussions here and entries in books …

How to strain wort before primary fermentation

I recently made a big beer (Dogfish Head 90 minute clone) with an OG around 1.11. I had never tried to strain wort before moving to a primary fermenter, but thought it would be a good idea since this had so many hops. So, I used the basic muslin bag and bungee cord method of putting the bag over my fermenting bucket and using the bungee cord to secure it. This seemed to work fine until I tried to remove …

Stalled fermentation

I've started brewing an Oktoberfest. It has been in primary for a little less than a week. The first 24 hours was good, super active. After about a day, it got pretty warm here, and the thermometer strip on my carboy read 80°. After that, my fermentation came to a screeching halt. I figured the warmer temp might have just sped up the fermentation process, but when I took a gravity reading, it said 1.022, my OG was 1.042. So …

Cider not fermenting

My first cider attempt. It's day three and see no activity in the airlock. So this is what I did. I juiced 20kg of apples and got just over 3 gallons of juice. I took a gravity reading of 1.050 at this point. I wanted to stick to a more organic method so I pasteurised the juice at 180/185°C for 45 minutes, at this point I added 13.5oz of brown sugar as I wanted to raise the specific gravity to …

Will my session beer be OK for 5-6 weeks in primary?

I am looking to finish off my leftover ingredients and can just about make a pale ale with OG ~1.04 or so. I'd like to get it started tomorrow, but I probably won't be able to rack it until the first or second week in January. Will it be OK in the primary for 5-6 weeks or should I wait until after the New Year to do it?

Bubbles restart after 1 month?

i've done 4 batches one month ago, one per day, day after day. My batches now are of 60L, and I use 2 30L fermenters for each batch. 2 of the 4 batches are the "same recipe", so I have 4 fermenters in "same conditions". So, bubbles stopped a long ago, there's no activity on any fermenter, beside 1 of them. What could be happening to it to restart to bubble? It can be a sign of too much time …

Primary Fermentation Increased

So I brewed an IPA about 2 weeks ago. I used a glass carboy for fermentation and for the first 2 days it was heavy bubbles then for the next week and a half there were a few tiny bubbles. I checked today and the bubbles have increased greatly. Why is this?

What prevents contamination during primary fermentation?

I'm about to start my first beer and I've been doing lots of research.. but a question I haven't seen answered is why isn't there more contamination during primary fermentation. For secondary the carboy, bung and co2 release seem like a closed system without the possibility for contamination. But during primary, it's a garbage pail with a lid. What's preventing undesirables from getting in the brew?
