Equipment

Attachment 22030
This requires the same basic equipment used for extract brewing with the following changes/additions:

10-gallon (or larger) brew kettle: The no-sparge BIAB method requires a brew kettle large enough to hold all of your boil water, sparge water, and all of the grain required for your recipe. No other pots or containers are used during this process so the brew kettle must be large enough to hold all of the water and grains at the same time.

An accurate thermometer: This is important so you can take accurate readings of your mash temps. Make sure to check the accuracy/calibration of your thermometer so you know it's giving you reliable temperature readings.

Digital thermometer with a wire probe: (OPTIONAL) used to monitor the mash temperature while the mash kettle is sealed.

Mesh voile cloth or other mesh bag: to line the inside of the brewing kettle. I used a large paint strainer bag from the hardware store. Another option is to use a bag made from voile cloth available at most fabric stores. The bag needs to be big enough to hold all of the grain that you intend to use without being too taught since this will make stirring easier.

Binder clips: Used to secure the mesh cloth/bag to the brew kettle or basket.

Attachment 22031
A simple overhead pulley system with a hook or carabiner attached: It should be able to support at least 50-pounds of weight since it will be supporting the weight of the grains and the water absorbed by the grains. I got all of these parts for less than twenty dollars at the hardware store. This should be attached to the ceiling or other overhead structure (directly over the brew kettle) in a secure fashion.

Attachment 22032
** OPTIONAL ** Turkey frying basket: I use a 44-quart Bayou Classic model B144 perforated basket. Shop around for these because prices vary from place to place. I paid something like thirty dollars for it on sale at sears.com. Measure your kettle and get a basket as large as possible that will fit. It needs to be large enough to hold all the grain for your recipe. I can fit up to 21-pounds of grain and 8.5 gallons of water into my kettle/basket with the equipment listed here.

I decided to use a steel basket with my BIAB process because I was concerned about the possibility of grain bag disasters from burns or tears. My family & friends like big IPAs so I needed something that could support up to 20+ pounds of grain PLUS the weight of the absorbed water without tearing. The basket provides much more support and peace of mind when lifting heavy, hot grains from the brew kettle. The basket handle provides a convenient and secure attachment point when using a pulley and it also saves my back since I don't have to stand there holding the grain bag over the kettle while it drains.

STEP 1: Prepare equipment

Check valves on brew kettle, are they closed? Are all bits and pieces in place and watertight?

Attach mesh bag to inside of steel basket using binder clips.

Test basket/pulley/kettle placement so basket lifts smoothly in and out of kettle. To avoid messes, the basket shouldn't pull on the kettle or swing to the side when lifted from the kettle.

STEP 2: Heat water

Mash temperature for this batch is 152-degrees F.
Strike temperature is 160-degrees F.

Attachment 22034

Add 7.5 gallons of water to boil kettle and heat to the required strike temperature

While heating the water, lower basket into kettle so it heats up as well

STEP 3: Mash-in

Attachment 22035

Once you have reached your target strike temperature, turn off the heat and slowly add your grains while stirring the mash. If possible have someone help with this so one can pour grains while the other stirs. Stir well so there are no grain balls or clumps.

Attachment 22036

Once all the grain has been added and stirred, you should be at or near the required mash temperature.

If your mash temperature is too high, add cold water to lower the temperature. If it's too low, add hot water or heat to raise the temperature. It may take some practice to hit your mash temperature and hold it. This can change based on many factors such as the weather, your equipment, etc.

Here in Florida I am able to maintain a constant mash temperature for at least an hour during the warmer months, but when it’s very cold outside it is a bit trickier. Wrapping the mash kettle with a towel or blanket or sleeping bag will help maintain a constant mash temperature.

Hitting your mash numbers consistently is an art that takes practice. After a few batches, you'll get the hang of it.

Attachment 22037

Cover the kettle and monitor with your thermometer and maintain the required mash temperature.

Once the mash is completed remove cover and stir gently.

STEP 4: Mash-out

The mash-out step is important when doing no-sparge BIAB because it helps improve brewhouse efficiency by making the grain bed more fluid. This helps you get the most amount of sugars/wort possible when draining the grain in the following steps.

Attachment 22038

Fire up the burner and stir the mash while bringing the temperature up to the required mash-out temperature of 170-degrees F.

Once mash reaches 170-degrees, cut the heat, cover, and let sit at 170-degrees for 10-minutes.

After 10-minutes at 170-degrees, mash-out is complete.

STEP 5: Lift, Drain, Squeeze Grains

Attachment 22040

Attach your pulley to the basket and slowly lift the grain basket from the kettle and secure rope/pulley so that it allows the basket to hang directly above the kettle while draining.

*OPTIONAL STEP* Wort will continue draining from the grains for up to 30-minutes so I like to leave the basket suspended above the kettle for at least 30-minutes to get as much wort as possible from the grains. This step is not mandatory if you already have enough wort in your kettle.

Attachment 22041

After draining, use a flat lid from a small saucepan (or something similar) to press down on the grains to squeeze as much wort as possible from them. You don't have to go crazy here, just press the grains down firmly, but carefully, with the lid.

Attachment 22042

Remove the basket from the pulley and dispose of the spent grains.
