Has leftover sediment after primary fermentation got yeast?

[johndavies86]

I was just wondering if after primary fermentation if the sediment at the bottom contained usable yeast for another batch? Ive read on jere about people using the same yeast but im curious as to how you would do it? Also would it still work if you used a kit?

Yes, it is where the most the yeast ends. There is also other stuff in there (trub). So reusing quickly is fine, but if you want to store it for a while in the fridge, read on washing yeast.

so the yeast I used recently I could actually store it and use it for everything I make in the future? Is it better just to stick to buying the packets?

If you follow very sanitary processes during the brewing process you can reuse the yeast. Otherwise you may be better off using the packets. $3-$6 for yeast is much better then losing a $40 batch.

There are some great posts on the forums regarding yeast reuse. Definitely check them out!

I generally use about a quarter of the cake for a similar gravity beer. Store in fridge in sanitized mason jars, use within a month and you don't need to wash it. Using a full cake is over-pitching.

General recommendation is to only re-use 5 times. Each time you use and collect the yeast, it is evolving. The way you use it will change it's characteristics, and the way you collect it selects certain properties.

With decent sanitation procedures you should be fine.

Aside from saving bucks, in few generation yeast comes in top form to ferment wort, some say that 3rd generation cells are most suited.
It is about transitioning from laboratory culture to beer fermentation culture.
