Ritterguts Gose is still made to the traditional German recipe.

Gose (Goes-uh) is a salty, sour, beer from Goslar, Germany that is brewed with at least 50% malted wheat (although a few historical sources say that Gose was brewed with 100% wheat [1]. Gose has a low hop bitterness and aroma and gets a lemony character from the use of coriander. The straw-like colored Gose (2-6 SRM) sits at a sessionable ABV around 3-5%, made up of mostly pilsner and wheat. Gose is usually unfiltered, so some haziness is to be expected [2].

Hop Weight Use Alpha Acids
Golding (UK) 2 oz Mash 8 AAU
Yeast / Bacteria
Name Laboratory Product ID Starter Attenuation
Lactobacillus Blend (brevis, delbrueckii, and plantarum) * Omega Yeast Labs OYL-605 None N/A
Brett Sacc Trois White Labs WLP644 1 vial in 500 mL DME starter for 5-8 gallons 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 [3].

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, make sure to add the hops to the mash.
  3. Sparge as normal.
  4. Bring the wort to a boil, add salt and coriander, and then turn the heat off (no need to boil for more than a couple of minutes).
  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, chill the soured wort down to ~70°F and 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.
