Homebrew Conversions: Grains and Extracts

Andy and I set out to find some gifts we think most, drug if not all, brewers could benefit from having. Here is our list of the top ten things we think you should have to make brewing more enjoyable and successful.

1. Refractometer

A refractometer allows you to read the specific gravity of a liquid without needing to take a large sample from your fermenter, as you would if you were using a hydrometer. This device requires just a drop of solution and a light source so you can read the gradations. In addition, the automatic temperature compensation (ATC) means that you do not have to do any computation to offset the temperature.

2. The Brew Hauler

The Brew Hauler is a carboy carrier that makes a glass or plastic carboy easy and safe to carry. The webbing is tough and strong and the buckle makes the carrier easy to load and unload. I do not (yet) have one of these but my friend Jason does. It is much easier to move carboys around with these, rather than using one hand to steady the neck and the other to cradle the bottom. That is an accident waiting to happen. This device can save you some time and energy and possibly help you avoid a trip to the hospital.

3. Carboy Cleaner

This bottle and carboy cleaner is ideal for getting that stuck-on schmutz knocked off the inside of the glass and get all the junk removed before you need the container again. I used to discard bottles that had not been rinsed well enough and had some remaining junk dried to the side. Of course, now I keg my brew, but the fact remains that without using some sort of device like this, quality cleaning is tough to ensure.

4. Carboy Sprayer

To go along with the cleaner above, you can hook up this sprayer to a faucet or spigot and spray water all up in your carboys and bottles to wash away all the schmutz you removed from the glass. Schmutz – I guess I like that word. This device will screw on most hose spigots and utility sink faucets but if you want to use it at the kitchen sink, chances are you will very likely need an adaptor.

5. Digital Scale

A digital scale like this one will help you measure out precise amounts of hops, and even help you when recipes call for a quarter pound of grain, for example, and your homebrew store only sells it by the pound. No more guessing. This is all part of the standardization of your brewing process. Rather than estimating, you will know for certain that your measurements are repeatable so you can replicate a process, or opt to change it.

6. Beer Glasses

These are advertised as “craft beer” glasses. Let’s be honest – that does not really mean anything. They are cool beer glasses that you can feel good about serving your homebrew in. Personally, I have a set of non-descript pint glasses, similar to what you would find in most bars. However, once I break enough of them I will probably get a set like this. Truth be told, there are optimal shapes of glass for different kinds of beer, but mostly it is just an intermediary vessel that goes between the long-term storage (keg or bottle) and the main processing unit (my innards).

7. The Complete Beer Course

Educating yourself on the finer points of beer is always good for someone who is in the business or hobby of making beer. All of us, no matter how experienced, can find something to learn in this book, and this piece is good for beer lovers young and old. While it is not technically a homebrewing book, it is informative and can help beer lovers understand what the different ingredients are and how they affect the flavor of their favorite drink.

8. Periodic Table of Beer

This is a good guide for how to classify beers, so that if you want to make a porter, for example, you can see what is related to porters and get an idea for something else to try that you might also enjoy. It is not an official BJCP diagram but it is a general way to classify beer. Fun, clever, and useful. Exactly the type of thing I enjoy. I think you will as well.
Anytime you are trying to convert homebrew recipes to your available ingredients, check
you have to do a little figuring and guessing, even experimenting. This is because different ingredients have different properties and substituting one for another may not give you the exact end product you want. However, in the end it will be beer, so you will never stray too far off course if you follow the directions and get good approximations for your substitute ingredients.

One problem comes in converting grain recipes to extract. I do not like to do this is because my grain recipes list specific grains I want in the mash. If I try to use an extract, I do not know exactly what kinds of grains were used. Plus, my general philosophy is that the more an ingredient is processed, the more it loses nuance and character. The base malts do not differ significantly but you can get more variation with actual grains than you can with liquid extracts. The same goes for the difference between dry malt and liquid malt. The more you process something, the more nuance you lose. This is not a scientific statement, I know, but I believe it to be true.

But you did not come here to hear Uncle Carl blather on about his philosophies regarding converting recipes. You probably want to know how to do it. Note that for some of these calculations I say, “about.” This is because I tend to round these figures to make it as easy as possible to get to work making beer. If I have a little bit extra or a little less, I do not worry about it. I generally stop worrying about measurements when I get to a quarter pound. So if I calculate to the quarter pound and find myself more than halfway to the next quarter pound, I just round up. Likewise, I round down where appropriate. Like I said before: in the end, it will be beer.

Grain to Liquid Malt Extract

Multiply by 0.75.
10 pounds of grain * .75 = 7.5 pounds of liquid malt extract

Liquid Malt Extract to Grain

Multiply by 1.33
7.5 pounds of liquid malt extract * 1.33 = about 10 pounds of grain

Liquid Extract to Dry Extract

Multiply by 0.8
6.6 pounds of liquid malt extract * .8 = about 5.25 pounds of dry malt extract

Dry Extract to Liquid Extract

Multiply by 1.25
6 pounds of dry malt extract = 7.5 pounds of liquid malt extract

Grain to Dry Extract

Multiply by 0.6 (.75 * .8 = .6)
10 pounds of grain * .6 = 6 pounds of dry malt extract

Dry Malt Extract to Grain

Multiply by 1.67
6 pounds of dry malt extract * 1.67 = about 10 pounds of grain
