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.
9. Stainless Steel Growler
This is a great option for people who want to carry their beer somewhere, maybe to a holiday party, but do not want to accidentally break the vessel that they are carrying their beer in. This thing is completely drunk-proof. Sure, it might dent, but it will not shatter. No more tears over broken growlers and lost beer. Save you tears for when you find your friends drank more than you had hoped.
10. Portable Corny Keg Charger
Leave the five-pound canister of CO2 at home and use this little piece of goodness to dispense the beer from your keg. This whole thing slips in your pocket and beats the heck out of carrying the gas bottle and lines somewhere when all you want to do is share your beer with your friends. I bought one of these a couple years ago because it was on sale and after using it once I was hooked. It will change your whole life. If your whole life is beer dispensing, anyway. And it should be.
