My favorite interpretation of the Berliner Weisse style is Dogfish Head's Festina Peche. DFH describes the Festina Peche as a "refreshing neo-Berliner Weisse" to be consumed during the "sweaty months." What separates Festina Peche from the traditional Berliner Weisse style is the use of peaches during fermentation. The natural peach sugars are utilized by the yeast and lactobacillus and eliminate the need to add syrup to off-set the tart/sour.
As any good homebrewer wishes to do, I set out to duplicate the recipe and add my own flair to it. Approaching brewing a Berliner Weisse is different than other beers. There are many ways to brew a Berliner Weisse. The traditional method utilizes a decoction mash and first wort hopping with a sparge directly into the fermenter with no boil. I fully admit I didn't perform the traditional method. First, a decoction mash is a pain the ass. Second, I don't trust the natural bacteria growing in my mash tun or the grain to provide me with a decent beer. It might just do it, but I sure don't want to find out. Other methods include performing a normal sparge and performing either a short boil or a long boil. Some even perform a sour mash and then boil once the desired level of sourness is reached.
Next, you need to choose your bacteria and yeast. Choosing your Lactobacillus strain can be just as difficult. Do you want a homofermentative Lactobacillus strain that will produce lactic acid and little else or a heterofermentative strain that will produce ethanol? Typically a homofermentative strain will produce a more sour, tart drink but will give little to no alcohol. Remember this from Biology?
Yeah, I don't either. You can bet I would have paid better attention if this was how it was presented! The yeast strain is rather easy to pick, a clean german ale yeast is typically used. A traditional Berliner Weisse will also use Brettanomyces Bruxellensis during secondary or at bottling.
Below is my interpretation of the Festina Peche / Berliner Weisse:

Boil Time: 10 Minutes
Ingredients:
------------
Amt Name
4 lbs 8.0 oz Pilsner (2 Row) Bel (2.0 SRM)
3 lbs White Wheat Malt (2.4 SRM)
0.75 oz Tettnang [4.50 %] - First Wort Hop
1.0 pkg Berliner Weisse Blend (White Labs #WLP630 Yeast)
1.0 pkg Lactobacillus Delbrueckii (Wyeast Labs #5335 Yeast)
Mash Schedule: Single Infusion, Batch Sparge
Total Grain Weight: 7 lbs 8.0 oz
----------------------------
Name Description Step Temp Step Time
Mash In Add 9.38 quarts of water at 159.1 F 149.0 F 90 min
Sparge: Batch sparge with 2 steps (1.74gal, 3.18gal) of 168.0 F water
Notes:
Cool wort to 100 F and pitch Lactobacillus Delbrueckii (Wyeast #5335)
Wait 2 days and pitch Berliner Weisse Blend (While Labs #WLP630)
After 2 weeks, move to secondary fermentation and rack onto 3 lbs, 1 oz of peach puree.
Secondary fermentation for 6 months and then rack off peach puree into tertiary.
Tertiary for 2 weeks or until clear.
Fermentation temperature ~68 degrees
Bottle conditioned with carbonation level of 3.2 volumes of CO2 with table sugar
Explanation of my process:
I did not perform a traditional decoction mash due to the increased time required for this process, nor did I do a no boil method due to wanting to exactly control the bugs/yeast that went into my beer. I only cooled my wort to 100 F since Lactobacillus Delbrueckii liking very warm temperatures. The wort cooled naturally to 78 degrees in 2 days when the Berliner Weisse Blend was pitched. The amount of peach puree was guess. However, I'd rather have too little peach than too much peach. We've all tasted the nastiness that is Son of a Peach, and the last thing the world needs is a replica of that crappy, extract infused beer. I skipped on adding Brettanomyces Bruxellensis during tertiary or at bottling because Festina Peche has no apparent Brett character.

Good brewing and drinking all!
