Tertiary fermentation in bottles?

Post by Stonch » Wed May 02, 2007 10:01 am

So far all of our brewing plans have assumed two stages of fermentation - primary in a bucket and secondary in a pressure barrel.

Does anyone here put their kit beer through three stages of fermentation - i.e. a week in primary, a week in secondary then transferred to primed bottles for a third stage and conditioning?

It all depends on what I am brewing.

Currently I have a beer that I racked to secondary about 10 days ago. This was racked on top of cherries. In the next few days (well, whenever I actually have any time - seems a rare commodity theses days) I will be transferring to bottles. This could be considered Tertiary fermentation.

Personally, if I am transferring to a vessel and priming that vessel I don't consider it a stage of fermentation, rather the maturing stage.....

Some people (mainly the Americans) will have numerous fermentation stages, particularly for the bigger beers. I think that the main reason for this is to get it off the yeast cake.

I personally don't see any reason for anything other than primary - unless there is a specific reason (such as adding extra ingredients).

Of course, if you are making something like a mead, then since this is going to be fermenting over a number of months then you want to get it off the yeast so transferring a few times is a good idea.

Thanks pal.

So you're making a fruit beer. What kind of beer is it? An English-style ale? Have you done this before? I'd be interested to know what can be achieved.

It was a very basic beer. I think I had 4kg of marris and 250g of crystal. Can't quite remember the hops I used but around 50 IBU (iirc).

After this had fermented down to 1.007 I added 1.5kg of cherries to a secondary fermenter (the cherries had been fresh little under a year ago - I had removed the stones and frozen).

The beer has a great taste and nice red colour, unfortunately there is little to no taste or aroma from the cherries themselves. I had wanted subtle but I also wanted detectable. It is likely the source of the cherries rather than the amount.

Still, it has increased the ABV and hasn't ruined the flavour. I look forward to bottling this one and serving it to a few mates during a summer BBQ :D

Another option to adding fruit is to add fruit extract. I would probably do this next time.
