Recipe: Quick (Kettle) Soured Berliner Weisse January 10, 2016 16:24

Like most of you, we're homebrewers too! We've decided to start a series that documents the recipes and process for some of the beers that we brew. We've decided to start with one that has received great feedback from our local beer community - it's a quick soured Berliner Weisse.

Many people who haven't brewed a sour beer are intimidated by the thought.  A "Kettle Soured" Berliner Weisse eliminates most of the "intimidating" aspects of brewing a sour beer:

  • A kettle soured Berliner Weisse eliminates the "wild yeast" aspect.
    • You boil the beer after it's been soured, so your kegged/bottled beer is no different than the Stout, Porter, IPA, etc., that you currently brew. The boil kills off the souring bacteria eliminating its presence post-boil, but leaves the sour bite behind!
  • A kettle soured Berliner Weisse can soured in as little as 24 hours.
    • A lot of "sour beers" take 1+ years before they are "ready". Following the recipe/process below, your beer will generally be soured in 24 hours, and ready to drink in about the same time as your standard ale.

Recipe Stats:

  • Original Gravity:1.031
  • 4.5 IBU
  • 2.8% ABV

Water Profile:

  • We generally use reverse osmosis water when brewing, so we build the water from scratch. The following profile was used for this recipe:
    • Ca: 52.5 ppm
    • Mg: 9.9 ppm
    • Na: 13.3 ppm
    • SO4: 66.9 ppm
    • Cl: 84.8 ppm
    • HCO3: 14.4 ppm


  • 56.8% Pilsen Malt
  • 40.3% Wheat Malt
  • 2.9% Acid Malt

Mash Profile:

  • Mash @ 150°F for 60 minutes
  • Chill wort to ~110-115°F and begin souring process

Souring Process:

  • During the souring process, you want to hold your wort in the 110-115°F range. We have an electric brewing setup, and use the heating element in the kettle to accomplish this.
    • If using a carboy, you can use a FermWrap plugged into a temperature controller. We've also heard of people using household heating blankets to maintain the temperature.
  • Add unmilled malt to wort. We use a ratio of .5lb Acid Malt & .5lb 2 Row per 5 gallons of wort. You can bag this in a mesh bag, or let it float loose if you have a way to filter it out before the boil.
  • Run CO2 through wort to purge O2 from wort & vessel. You want to eliminate as much O2 during the souring phase as possible.
  • Hold the wort with the unmilled malt at 110-115°F until desired pH/sourness has been reached. Most information you read will suggest something in the range of pH 3.2-3.6; the lower you go, the more sour it will be and the more stressful for the yeast.
    • Expect to hold at this temperature for 24 hours or more to reach the desired pH. If you do not have a pH meter, we'd suggest starting the boil after 24 hours.
      • We use a pH meter from Omega - it's linked at the bottom of this post.
      • We normally boil when a pH of 3.2-3.3 has been reached.


    • Once you've reached your desired pH, remove and discard the grain, then boil the wort for 15 minutes.
    • Add 4.5 IBU of Spalt Select @ 10 minutes.
    • Chill wort to 68°F and add yeast.


    • Ferment with US-05 @ 68°F for 7 days.


    Getting started with BIAB (Brew In A Bag) Brewing July 22, 2015 21:37



    Want to start brewing with minimal investment? Are you already brewing using extract and want to move to all grain? Already brewing using the all grain method and looking for a quicker, easier method that requires less space and less cleaning? If your answer to any of the above questions is "Yes!", then BIAB is the method for you!

    Here's a quick list of what you will want for equipment if you're looking to get started in BIAB. Keep in mind, this is a general list and preference may vary from person to person.


    The most common batch size for homebrewers is 5 gallons, and this is because it's the perfect size to fill one cornelius keg (19 liters). If you're aiming for a 5 gallon batch, we suggest brewing with a 15 gallon pot. The 15 gallon pot will give you plenty of room for high gravity brews, and will also allow you to brew the odd 10 gallon batch if you want. If a 15 gallon pot just isn't feasible, a 10 gallon pot will work, but can limit you when it comes to higher gravity beers and will prevent you from brewing larger batches.

    You can generally find a suitable pot at your local homebrew shop, or at a restaurant supply store. Here in Canada,  a 15 gallon stainless steel pot can be purchased for $115CAD.

    Heat Source:

    Depending on your batch size, you may be able to use your stove as a heat source. Our suggestion is for anything 5 gallons or larger, that you use a dedicated heat source. A "turkey fryer" style propane burner is a high powered, low cost heat source for brewing. Some people prefer electric, and here in North America, hot water heater elements are a widely used method to heat wort for homebrewing.

    In Canada, a turkey fryer can be purchased as cheap as $60CAD at most hardware stores.

    BIAB Bag:

    You get that from us ;) We offer a few different styles. One is designed specifically for square coolers - this is a hybrid BIAB method that is outside of the scope of this discussion. The other two bags (classic & premium) are basically the same, except the premium bag includes a ring of webbing with a velcro strap around the top. The webbing and strap are designed to secure the bag in place while it's in your pot.

    Our bags are $34.99 and $39.99CAD, with free shipping world-wide!

    Chiller (Optional):

    The chiller is designed to chill the wort (unfermented liquid) after you're finished boiling. Using a chiller is fairly standard procedure, however, some people feel the chiller is an unnecessary piece of equipment. If you do a quick search for "homebrew no chill method" you'll find a lot of information on this topic.

    A standard immersion chiller can be found for about $85CAD, but as mentioned, this item may be considered optional.


    You'll still need your other equipment - buckets, carboys, transferring lines etc., but you can get by with just a couple of food grade buckets, and some siphon hose to transfer the liquid. 

    As you can see, getting started with brewing using the BIAB method is easy and inexpensive. The necessary equipment can be found new for as low as $210CAD.
