Should i stir primary fermentation

You should store your opened bottle of wine away from light and under room temperature, making the fridge the ideal place. Racking is an essential part to making any sound wine. It is a process that, on average, should be performed 2 to 4 times throughout the winemaking process.

Doing so in a timely manner will aid in the clarification of the wine and help to inhibit the production of unwanted off-flavors. Here are some other tips for producing wines with high alcohol levels. Pre-Start The Yeast. Make a wine yeast starter 1 to 2 days before you start the wine. Maintain Warmer Fermentation Temperatures.

Normally, we recommend 72 degrees Fahrenheit as the optimum temperature for a fermentation. Provide Plenty Of Air. Fermentation is finished when it ceases to off gas. The airlock is still and has reached equilibrium. If you brew in glass, look at the beer, the yeast ceases swimming and flocculates settles on the bottom. Pull a sample and taste it. Typically, the fermentation will need to be transferred into the secondary fermenter around the 5th day of fermentation.

But, not all fermentations are the same. Some ferment so hard and fast, that by the fifth day, the fermentation is completely done. On occasion, others will take much, much longer. Botulism is a rare food poisoning caused by toxins created by bacteria called Clostridium botulinum.

However, there have been instances of tainted wine made in prison : Some inmates have contracted botulism from batches of "pruno," where potatoes have usually been the culprit. Should i stir wine during primary fermentation? Asked by: Dr. Hilario Cormier. How long do you ferment wine for? How do you know when homemade wine is ready?

Can you double ferment wine? What happens during secondary fermentation of wine? Within 12 hours at the most, the yeast should have multiplied to begin its sugar to ethanol conversion. It does its work slowly, exhibiting a milder, gentler krausen. Lagers may take 15 — 28 days for full fermentation , requiring a well-found patience.

Off flavors include index-card, musty, used booky : sounds crazy, but this is what it brings! Another violent result of oxidation is the formation of Acetaldehyde. Acetaldehyde not only forms due to under-pitching and O2 exposure, it will also reconvert your alcohol back into itself, a rancid and villainous contaminating compound. After cold break solids falling out during cooling and cool-down, stir away! Remembering that all post-boil contact must be sanitary, if stir you must do it in a manner in which the lid keeps the fermenter mostly covered.

The stirring introduces O 2 to the wort and mixes the yeast well before its brief pre-fermentation rest. Consider this a preemptive stir allowing the greatest possible success for respiration and cell multiplication.

See my article for best handling of pre-pitch yeast: article on hydrating yeast. Rest it on the floor with a towel underneath for cushion. Pitch the yeast on brew day, fermentation picks up, there is healthy bubbling , swimming, and a krausen on the beer, even if not the most vigorous. Then, crickets …the foam dies down, a heavy slurry rests on the bottom. Taking a hydrometer reading, the gravity reads 1. The OG was 1. Lots if opinions, so I'll toss mine out.

I have had problems with H2S a few times in the past. Each time and one time was with a W. There is lots of scientific info out there that says yeast need oxygen the first several days of fermentation. One would be hard pressed to argue with that. This says to me that if the lid is snapped down per W. I would guess that W. E figures the chances of H2S are less likely than an inexperienced wine maker ruining the wine with bad sanitation practices.

So, I try to use great sanitation practices, and during primary fermentation while SG is above 1. If you don't want to stir, at least leave the lid settin on top and not snapped down. Robie: My understanding is that one way to ensure sufficient oxygen is in the must is to stir vigourously before pitching the yeast. I also use a large primary with a loose fitting lid, so there is probably some air sneaking into the bucket too. Haven't had any H2S problems; however, Winexpert uses a broader range of yeast than the other kit manufacturers.

Do you recall what yeast was used when you had the H2S problem? MontyPython Noob Vintner. Joined Jun 22, Messages 23 Reaction score 0. Making my first batch and trying to gain some insight into the whole stirring thing as well. I'm using a Vinifera Noble - Carmenere kit Using the Lavin K yeast , and there was nothing about stirring, or anything that said "leave the lid on loosely".

I was getting a pretty strong smell also on day 3. That old yeast, dirty sock, slight rotten smell. Moved it into a vented area of the basement so that it didn't stink up the whole house.

I also cleaned out the wine that crepped into the airlock. Back on topic, however I'm now 5 days into fermenting. It's still bubbling like crazy, and I haven't yet unsnapped the lid, or stirred it.

Is it too late for this? Should I pop the lid off and give it a few good stirs, and then leave the lid on loose for the remaining few days of primary? It makes sense to let some O2 in, but then I keep reading things about, "use the barrier of CO2 at the top of the plastic primary fermenter to keep the O2 from spoiling the wine". All good info, but some of it contradicts others. I appreciate your advice! Stephen, I read once that you can ask 10 different wine makers a question and get back eleven different answers.

This is not rocket science, so each of us over a period of time tend to do things by "what has always worked for us". So, if you go by your kit instructions, using the kit supplied yeast, and it doesn't say anything about snapping or not snapping the lid down during primary, you likely won't have to worry about it, one way or the other Have you been taking specific gravity readings with a hydrometer?

Here is my own personal experience: During primary, the yeast need oxygen; during secondary and thereafter , they need to be kept from oxygen. That is a scientific fact, regardless of the kit instructions. Now that's why I stir during primary. While in primary, it is not a good idea to seal the wine from any and all oxygen. I believe the foam should be stirred in on a daily basis, better if done twice a day. Also, stirring is especially necessary if you have added a grape pack.

However, if no grape pack and if you are not getting a lot of foam and your lid is not snapped down sealed , you should be getting enough circulation to be OK. I say "OK", but I will always stir it anyway. Being OK is more true if you are using a very robust yeast like EC or EC and a few other of the "Mack Truck" yeasts; they are very good at getting the job done correctly, even under not so great conditions, like having the lid sealed during primary.

I typically don't use these particular yeasts, which is part of the reason why I got H2S in the past. Now if you don't practice very good sanitation, you would be better off not opening the wine to stir, but I'll assume you are going to always sanitize your stirring spoon and do it correctly.

My advice - Don't seal the lid during primary, don't leave lid so critters can get into the wine; stir the foam down at least once a day using a well sanitized stirrer That's one of eleven! Robie, Thank you for taking the time to chime in. VERY helpful! That's what I'm kind of gathering as I continue to do research.

Heh, 11 different answers seems only to be the beginning - and that's probably why there's 's of producers out there, all of which manage to make wine, but not all of them are able to make GOOD wine. I'm actually very excited about the learning process, and want to gather enough to not make unnecessary noob mistakes, but not so much that I don't have the opportunity to figure out what works for me. Otherwise I'll just be making the same wine that anyone else with the kit is!

Following your and a few others lead, I popped the cover this evening day 5.
