Berliner Weissbier

Berliner Weisse is a top-fermented, bottle conditioned wheat beer made with both traditional warm-fermenting yeasts and Lactobacillus culture. They have a rapidly vanishing head and a clear, pale golden straw-coloured appearance. The taste is refreshing, tart, sour and acidic, with a lemony-citric fruit sharpness and almost no hop bitterness.

Served in wide bulbous stemmed glasses, tourists in Berlin will often order on as a "Berliner Weisse mit Schuss: Himbeere" or "Berliner Weisse mit Schuss: Waldmeister". These are syrups that are added to make the sourness more palatable. Himbeere is raspberry (red) and Waldmeister is woodruff (green).

Typical average alcohol by volume (abv) range: 2.0-5.0%

General Best Practices

• Don't sour mash. Its too risky for off flavors
• Limit CO2 and do not aerate before pitching
• Pitch Lactobacillus between 90F and 120F depending on your Lactobacillus strain or blend for ~ 1-4 days (for more details see the Sour Worting page).
• Create a 1 liter Lacto starter for each 5 gallons at least 2 days in advance of brew day.
• Pitch Brettanomyces after cooling down after Lactobacillus fermentation phase

Fermentables

Malt	Weight	%
Floor-Malted Bohemian Wheat (DE)	3 lbs	30
Floor-Malted Bohemian Pilsner (DE)	7 lbs	70

Extract Version *	Weight	%
Briess CBW® Bavarian Wheat Dried Malt Extract (or similar)	3 lbs	50
Briess CBW® Pilsen Wheat Dried Malt Extract (or similar)	3 lbs	50

* Note about the extract version: Devin Bell has also used 70% wheat DME to 30% pilsner DME and 100% wheat DME with good results. Briess CBW® Bavarian Wheat DME is 65% wheat and 35% barley.

Hops

No hops if possible. If hops have to be used for legal reasons (for commercial breweries, for example):

Hop	Weight	Time	Use	Alpha Acids
Golding (UK)	2 oz	10 min	Mash	8 AAU

Yeast / Bacteria

Name	Laboratory	Product ID	Attenuation
Lactobacillus Blend (brevis, delbrueckii, and plantarum) *	Omega Yeast Labs	OYL-605	N/A
Brett Sacc Trois	White Labs	WLP644	87.5

* If OYL-605 is not available, substitute it with a probiotic culture such as Goodbelly Mango or Swansons Plantarum. See Culturing From Probiotics .

Steps

1. 1-2 days before brewing make a 1 liter starter of 1.040 wort, and add your vial of WLP644. Let it sit at room temperature until use. Also make 1 liter of 1.040 wort, and pour OYL-605 into the starter. Incubate 24-48 hours at room temperature to increase the cell count.
2. Mash in at 145°f for 60 minutes; if hops have to be used, then make sure to add the hops to the mash.
3. Sparge as normal.
4. Bring the wort to a boil and then turn the heat off.
5. Adjust PH ~4.2 to limit growth Clostridium butyricum and other potential off-flavor bacteria. Not necessary, but this is a best practice suggestion. See How to Pre-Acidify for instructions.
6. Chill the wort down to 95°f, and transfer to a CO2 purged carboy or keg. Add the 1 liter of OYL-605 Lactobacillus Blend starter. Allow it to sour for 24 hours. No external heating is required.
7. After the souring phase, pitch WLP644 Trois (boiling to kill the Lactobacillus before adding the WLP644 Trois is optional; see kettle souring). You can aerate if you feel necessary. After 2 weeks a stable gravity should be reached.
8. Rack or transfer off as normal to bottles or a keg.
