Secondary Fermentation

Hey guys,

I have been brewing for about 8 months now, and gone through about 9 batches of beer.  I started out with extract brewing and moved my way up to all-grain (so far only 1 brew I wasnt blown away by!).  I am now fermenting a batch of “sour beer” or Berliner Weiss from a recipe I found in the March/April issue of Zymurgy magazine.

Anyway, this is my first time attempting a sour beer and I just have one main question at this point.  Do I need to transfer this beer into a secondary fermenter and let it sit for a few months?  I do not quite understand the reason behind having a beer sit in a fermenter after it is done fermenting (which the process of fermentation has yet to take more than 2 weeks in my limited experience).

What is the benefit of putting a beer into a secondary fermenter and letting it sit for several months?  Why is this process so important to sour beers?  And should I be incorporating this habit into my other brews?

Im sorry for such a novice question, but I just cant seem to find the answer in any of my books.

Usually if you use a yeast or a sour bug strain along with a “regular” mash, it will take months for the bugs to sour the beer. If you did a sour mash procedure and are just using a regular strain of yeast, there would be no need to age in secondary being that you developed the flavor profile using a sour mash procedure.

beveragebob, plugged your city into the AR calculator: Las Cruces, NM = [1430.4, 248.7] Apparent Rennerian  The longitude figure needed has a - value.

I am using a sour mash procedure and regular strain of yeast.  So then in my case there is no benefit of letting this beer sit in a secondary fermenter?  Because the souring method happened before the boil, it will not sour any more than it is already.

you got it.

Thanks MB, I’ll change it here pretty soon.
