BBXSWL – Sour Weapon L (Lactobacillus plantarum Blend) – the second member of our Sour Weapon™ family

Availability: Limited

Source: Traditional Norwegian Kveik brewers.

The new De Lacto Standard! Our first official Lactobacillus culture, and it’s a beast. We’ve tested countless LAB cultures over the years, and this blend of Lactobacillus plantarum is the most brutally effective Lactic Acid producer we’ve found!

If you’re looking to drop the pH of wort as quickly and low as possible, Sour Weapon L is your go to Lacto blend. At 98F, we’ve had trial batches drop the pH of wort to 3.0 after just 24 hours. When pitched at 84F, pH should reach 3.5 in 24 hours.

This is the ideal bacteria blend to use for acidifying wort for quick/kettle sours, and is also very effective when co-pitched with a yeast strain. As with any Lactobacillus culture, we recommend only using in wort with zero IBUs as even small amounts of hops may prevent significant souring.

Product Category: Dusty Bottoms Collection™

The Dusty Bottoms Collection™ is our ode to unique and hard to find cultures sourced from commercial fermentations. As much as we love local yeast, there are just some flavors and aromas that can’t be reproduced by plucking yeast out of thin air.

Many of these cultures have been used for generations to make some of the most consistently wonderful beverages in the world. Whether it’s brewer’s yeast, Brettanomyces, or Lactobacillus…these aren’t Local Yeast by our definition, but certainly were local at one time.

  1. Nick yuill

    This is a great lacto culture, fast, multi dimentional sour. I have used this in a mix culture with sacch, funk weapon 2 and 3, along with other bretts and have been able to make diverse wild, farmhouse, and sour ales. Flavors of lemonaid and citrusy, balance well without getting too sour with no hops in boil and with raw ales.

  2. Joshua Jackson

    This is one of the best, most consistent lacto cultures available to Homebrewers. This (especially combined with Sour Weapon P) provides a clean, fast sour with very little additional input needed. While I generally follow Jeff’s instructions pretty clearly, with my last beer made with these cultures (a Cranberry Raspberry berliner weisse) I pitched at 90 and let it free fall to around 85 – 82 and still saw the pH drop to roughly 3.47 in 36 hours (on top of that the beer scored a 41 at 2019 NHC). Another great culture from a great company!
