Brew Like A Professional highlights brewers who started out just like you – home brewing enthusiasts with a passion for creating their vision of the perfect beer. Eli Trinkle & Matt Wisley, Lead Brewers at Upland Brewing Co., have collaborated to bring Two of Tarts passionfruit and mango gose to the homebrew scale – a gold medal beer from Upland’s kettle soured “Tart Series.” For those who truly want to brew like the pros, this recipe is the perfect challenge.
RECIPE: Two of Tarts
10 gallon batch (37.85 liters)
Original gravity (before fruit additions): 1.042
Final gravity: 1.009
- 7.75 lb (3.52 kg) Pilsen Malt
- 2.75 lb (1.25 kg) White Wheat Malt
- 2.75 lb (1.25 kg) Flaked Red Wheat
- 1 lb (0.45 kg) Carapils
- 0.5 lb (0.23 kg) Acidulated Malt
- One 3 lb 1 oz can of Vintner’s Harvest Passionfruit Puree
- One 3 lb 1 oz can of Vintner’s Harvest Mango Puree
Hops & Spices:
- 0.42 0z (12g) German Tradition. 6% AA. Boil 60 minutes
- 1 oz (28.35g) Sea Salt. Boil 60 minutes
- 0.92 oz (26g) Freshly crushed Indian Coriander. Flame out.
Yeast & Bacteria:
Note: Wyeast 5335 Lactobacillus buchneri can be used as an alternative for kettle souring if 5223-PC is not available. Homebrewers should monitor & adjust the Brew Day procedures as needed based on the culture’s performance and taste after souring.
- FermWrap or comparable fermentation heater
- Fermentation temperature controller
- 48 hours prior to the brew day, prepare a lactobacillus starter with the following ingredients:
- 45 grams dry malt extract
- 10 grams corn sugar
- 10 grams Calcium Carbonate (CaCO3, chalk)
- 1 gram yeast nutrient
- Bring to a boil in 500 ml of water in a 1-liter Erlenmeyer flask, cover and cool to 95° F (35° C)
- Add Wyeast 5223-PC Lactobacillus brevis and seal with a stopper and airlock.
- For the next 48 hours, keep the temperature of the starter as close to 95° F (35° C) as possible.
Brew Day 1:
- Single infusion mash at 152° F (67° C).
- Collect the wort in the kettle, then bring to a boil for 5 minutes to pasteurize. Do NOT add hops.
- Cool the wort to 95-100° F (35-38° C), then draw off half the volume of wort into a sanitized carboy to set aside overnight. (You may also sour the full volume of wort, but we find that souring half the batch leads to a better balance of acidity and fuller mouthfeel in the finished beer.)
- Add 1 teaspoon of food grade lactic acid to the wort in the kettle to inhibit the development of unwanted bacteria before the Lactobacillus brevis can get to work.
- Add the Lactobacillus brevis starter to the remaining wort in the kettle. Do not agitate the starter before pitching and carefully decant to leave the calcium carbonate behind.
- Cover the kettle. Tape the FermWrap fermentation heater to the outside of the kettle.
- Tape the temperature controller probe to the outside of the kettle and tape a folded wash cloth or similar insulation over the probe. Plug the FermWrap into the temperature controller and set the controller to 95° F (35° C).
- Insulate the kettle on all sides and over the top with blankets, then let sit overnight.
Brew Day 2:
- After 15 to 24 hours the wort should reach 3.5 to 3.7 pH and be tart to the taste. At this point, add the un-soured wort from the carboy back into the kettle.
- Heat the full volume of wort and boil for a full 60 minutes. Proceed as normal with the hops and other boil additions.
- Ferment at 68° F (20° C).
- Add fruit to primary once the fermentation begins to settle down around day 4.
