Question: What Is Secondary Fermentation Beer?

Secondary fermentation is a period of aging that occurs after siphoning or transferring your fermented beer to a secondary vessel after primary fermentation is complete. It is almost always used for higher gravity and highly hopped beers that need time to age before reaching their peak flavor and aroma.

Should I secondary ferment beer?

After two or three weeks, yeast starts to break down and contribute off flavors to your beer. Most homebrewers don’t ferment their beer long enough to cause any noticeably problems, but for those who choose to do a longer fermentation, racking the beer into a secondary fermenter or carboy is highly recommended.

What is a secondary fermenter beer?

Secondary fermentation is the process of taking your “finished” beer from your fermentation bucket, and transferring it to another container, usually a glass carboy, for a period of aging typically ranging from two days to several months. There are pros and cons to doing a secondary fermentation for your beer.

What is the purpose of secondary fermentation?

So, why would you want to take this extra step? The main purpose of the secondary vessel is to facilitate the settling of the yeast and to allow the beer to age. By transferring into a secondary fermenter, you’re removing the beer from the layer of sediment that accumulated during primary fermentation.

Does beer still ferment in secondary?

Whatever you call it, secondary is simply the vessel to which beer is racked away from the yeast and trub that remain after primary fermentation is complete.

Do you need an airlock for secondary fermentation?

You absolutely do not need an airlock for secondary, assuming you wait til fermentation is done. I’ve sealed a carboy with a stopper many times for a secondary, although these days I usually use foil.

When should I secondary ferment?

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.

How long do you leave beer in secondary fermenter?

The duration of a secondary fermentation or conditioning phase can vary from as little as a week to over 6 months. Actual time will vary and you should let your taste buds and nose determine when a beer is ready for bottling. During extended secondaries, you should make sure your airlock does not dry out.

How long is too long in secondary fermenter?

Beer can be left in secondary fermenters for up to 3 – 4 weeks for ales and up to 4 – 8 weeks for lagers and Belgians. Temperature is a factor. Keep ales at or below 64˚F (17°C), and lagers at 45˚F (7°C) or below. In most beers, 1 – 2 weeks is fine for secondary.

How do you know when secondary fermentation is complete?

The only way to be sure that fermentation has completed is by measuring the specific gravity. Ten days after pitching the yeast, you should take a sample of beer from the fermenter and measure the gravity. You then take another reading two days later, if both readings are the same fermentation has stopped.

Can I skip secondary fermentation?

A secondary fermentation in a carboy can be done without detriment to the beer if done properly. The main concern is the introduction of oxygen and contamination. With proper transfer techniques these can be mitigated.

When should I switch from primary to secondary beer?

You move to secondary after primary fermentation is done. This is usually determined by taking specific gravity readings and once they’ve been the same for 3 days primary fermentation is considered complete (~2+ weeks).

How long does secondary fermentation take?

Unlike the typical four to seven days the primary fermentation takes, the secondary fermentation will usually last anywhere from one to two weeks depending on the amount of nutrient and sugars still available. So as you can start to see, the secondary fermentation is much slower with less activity at any given time.

Can you leave beer in fermenter too long?

Beer, we always recommend that you bottle your beer no later than 24 days in the fermenter. You can go longer but the longer your beer sits the more chance you have to get an infection and get off-flavors in your beer.

When should I stop fermenting my beer?

Roughly one to two weeks from brew day, fermentation ends. Bubbles coming through the airlock become very slow or stop entirely, the specific gravity is stable and the cap of foam starts to subside.

Can you secondary ferment in a bucket?

If you really want to do a secondary without buying more equipment, you could use your bottling bucket as the primary fermenter, rack it into the fermentation bucket when it is time to do a secondary, and then back to the bottling bucket when you want to bottle.
