![]() Taking all of these factors into account how quickly can you bottle or keg from primary fermentation. This is after you’ve reached the final gravity. The rate of flocculation depends on the yeast strain, it can take anywhere between 3-4 days if you have a highly flocculant yeast strain to 1 – 2 weeks for a low flocculant yeast strain. Waiting for the yeast to flocculate (settle out) to the bottom of the fermenter avoids this issue. This means that when you bottle the beer you’ll have a large buildup of yeast sediment in the bottom of the bottles.Įvery time you pour a beer it will rouse the yeast and you end up with murky, cloudy beer. The other concern about bottling the beer too soon after primary fermentation is that a lot of yeast will still be up in suspension. The beer needs to be in contact with the yeast for this cleanup to happen, racking the beer off the yeast will leave these undesirable compounds in the beer after bottling. This is just one example of the conditioning phase of fermentation. In the next phase of fermentation, these byproducts are cleaned up by the yeast.Ī diacetyl rest, where the compound diacetyl is removed can take several days after the initial burst of yeast activity. It would be wrong to take the beer out of primary at this point though as there is still important processes being carried out by the yeast.īyproducts created by the yeast during fermentation are still in the beer and they are undesirable in terms of flavour. This burst of activity can be over in as little as three days if the beer is a low ABV, stronger beers will take longer and can take up to a week or more. After the activity in the primary fermenter has died down, take readings on consecutive days and when the gravity of the beer is stationary (i.e stops falling) you know the yeast have fermented all the available sugars. It is easy enough to see when this has happened by using a hydrometer. ![]() The main goal of fermentation is for the yeast to turn fermentable sugars to alcohol. If you do want to get a beer out of primary and into bottles in a quick turnaround, what is the timeframe? Of course, there is no easy answer, there are however some ways to estimate it. This works best for me and is what I recommend under most circumstances. I almost always ferment my beers for 3 weeks in the primary fermenter. Whereas giving time for the beer to condition in the fermenter, means a shorter time after bottling until the beer is at it’s best for drinking. I am of the opinion that, the less time you condition in the fermenter, the longer the conditioning time in the bottle. I’m not saying the beer will be bad, it just won’t be as good as it could be. Take my advice, the more you rush a beer, generally, the quality will diminish. It is an exciting process and sometimes the patience required to go from brewday to trying the beer is hard to find. I have written about how long it takes to brew beer before. How Quickly Can I Move Beer From The Primary Fermenter?įirst of all, I understand the desire to get a beer done as soon as possible. How Long Can You Leave Beer In The Primary Fermenter For?.How Quickly Can I Move Beer From The Primary Fermenter?.Let’s start by looking at the first point of, “how quickly you can move a beer from the primary fermenter to bottles/keg?” The two points can have different answers depending on a whole load of variables. How long can I leave it in primary without affecting flavour before bottling How quickly can I ferment my beer then get it into bottles ![]() It seems the two sides of the coin are either I guess the confusion arises with regards to the period of time in the primary fermenter because of a couple of factors. If you aren’t using a secondary vessel to ferment in, the question then becomes a case of how long is enough and how long is too much time in primary? I’ve even talked about it myself, with a couple of exceptions like extended maturation times and adding fruit or wood to a beer, I don’t bother with secondary vessels and neither should you. The general consensus among home brewers is that racking a beer to a secondary fermenter is often unnecessary. That is what we are going to cover in this article. I’ve been asked this question a couple of times now, “How long should primary fermentation take?” or “How long can I leave the beer in primary for?”.
