Congress at Home: Basic Malt Evaluation for Homebrewers

Are you looking for simple tools to assess the quality of new malts for your homebrew? If so, this article is for you! Homebrewers can use the “Congress at Home” mash technique to evaluate the quality of their malt at home using common kitchen items. This method is quick and easy and can give you a good indication of how your malt will turn out when used in a beer. Let’s take a look at how to use this handy technique.

What is the Congress at Home Mash Technique?

The Congress at Home mash technique was popularized at the National Homebrewer’s Conference in 1993. This method of malt evaluation is simple, requiring only common kitchen items and a thermometer. The Congress at Home mash technique boils down to performing what is essentially a mini-mash at home in order to assess the quality of your malt.

Preparing for the Congress at Home Mash

As noted, the Congress at Home mash technique only requires a few common kitchen items as well as a thermometer. Here’s what you will need:

• 2-quart saucepan
• Mesh strainer
• A thermometer
• 1 lb of malt

Be sure to gather all the necessary items before beginning your evaluation. You will also need 1.5 quarts of distilled water.

Performing the Congress at Home Evaluation

Now that you have the necessary items and ingredients, you can begin the Congress at Home evaluation of your malt. Here are the steps involved in this mini-mash at home:

1. Bring 1.5 quarts of distilled water to a boil in your saucepan.
2. Add 1lb of your malt to the boiling water and stir in order to moisten all the malt.
3. Allow the malt to dry in the pan for 5 minutes.
4. Place a mesh strainer over a large bowl and pour the malt/water mixture into the strainer, allowing the liquid to collect in the bowl below.
5. Discard the grains in the strainer, and pour the liquid back into the saucepan.
6. Bring the liquid back to a boil, and then remove from the heat. Note the temperature of the liquid. It should be approximately 160°F (or 72°C).
7. If the temperature is not 160°F (72°C), continue to boil until you reach the desired temperature.

Once you have completed the above steps, you are ready to begin evaluating your malt. The fluid in the bowl should be a light amber-colored liquid — this is the sugar-extract that was drawn out of the malt. Using a clean spoon, you can taste this liquid. The liquid should have a sweet, malty flavor and should not taste bitter or sour.

Evaluating Your Malt

Now that you have tasted the liquid, you can make your final evaluation. Here are the indicators of quality you are looking for:

• Malt Should be Sweet: If the liquid has a strong sweet flavor, this indicates that there is a healthy index of sugar present in the malt.
• No Bitter or Sour Tastes: If you detect any bitterness or sourness in the liquid, this indicates your malt has undergone either a premature or extensive breakdown of complex sugars — both of which can negatively impact the flavor of your final beer.
• Light Amber Color: A light amber color is a good sign that the malt has a healthy quantity of unfermentable sugars, which will help to improve the body and mouthfeel of your beer.

If your malt passes all these tests, it’s a good sign that you are on the right track to making a great beer. If you detect any unpleasant tastes or colors, it might be worth trying another malt before brewing your beer — it could make all the difference!

Conclusion

Congratulations! Now that you’ve completed the Congress at Home malt evaluation, you can
