Today, we’re going to go over some tips on how to buy beer.

Before you throw up your hands and say, “Please … what is there to know about buying beer?! You enter a store that sells it, and you buy it!”—let me explain.

If you drink mass-produced lager and are perfectly happy with that, you don’t need this advice. The one thing the “big boys” in the brewing industry are good at is making their beer exactly the same, every time, and getting it to you as fresh as possible, as often as possible. But if you are like me and love craft beer—in other words, you look forward to having your taste buds challenged and your mind blown—this advice will help.

I have some good and bad news for you. First, the bad: There is bad beer everywhere. The good news: There is excellent beer almost everywhere, and if you follow a few rules, you can greatly increase your chances of finding some great beer.

How am I qualified to tell you, the wise consumer, about this? I am what is called a certified cicerone. Think of it as the equivalent of a sommelier (a wine “expert”) for beer. I spent a year studying (after 23 years of exploring and learning on my own) for a 4 1/2-hour exam that only 33 percent of all test-takers pass. (This is only the second level of a four-level system of certifications, by the way.) In other words, when it comes to the subject of beer, you can go very deep.

Anyway, enough about my bona fides; let’s jump into the rabbit hole.

1. Beer goes bad at varying rates. A can or keg is ideal for protecting beer, because light, oxygen and heat are beer’s worst enemies. The brown bottle offers the next-best protection, followed by green and clear bottles, which provide almost no protection. Also, refrigerated beer is the best to buy. There are many reasons for this, but suffice it to say that beer stored in cold, dark places is preferable.

2. Check the dates. Many craft breweries stamp or print the bottling date somewhere on the packaging.

Hoppy beers are the first to go bad. This is due to the breakdown of the various hop compounds in the beer, as well as possible exposure to UV rays (Ever had skunky beer, anyone?) If that IPA is more than three months old, it probably isn’t what the brewer wanted you to taste—especially if it was not refrigerated or protected from light.

Three to six months is good for most other styles. There are major exceptions to this—for example, many Belgian trappist styles and sour ales last longer, as do stronger ales such as barley wines and imperial stouts—but a good way to look at it is this: The brewer would not have packaged and released the beer if he or she didn’t think it was ready to drink. I have saved enough bottles—and been subsequently disappointed—often enough to now seriously limit the number of beers I cellar.

3. Crowd-sourcing sites like BeerAdvocate are your friends. BeerAdvocate is a website that allows users to add, rate and review beers, as well as breweries and craft-beer bars. If you have any questions or are wondering what the beer you’re looking at in the store is, you can look it up there and get some generally thoughtful reviews.

Many places sell or serve craft with employees who can’t offer you much help—but luckily, you are armed with a powerful pocket computer that can access the vast information resource that is the Internet. Remember to consider the source, however.

4. Don’t be afraid to send that beer back. You might feel odd doing this—but a beer you’ve been served may be flawed. It may be the beer itself is no good and suffers from off-flavors; the keg may be old; or the lines that bring the beer to the tap may need cleaning. You don’t need to pay for a bad drink, and while a truly great beer bar will rarely, if ever, make these mistakes, they’ll gladly make up for it if they do.

And if a business reacts poorly when you send a beer back … be glad: You now know where not to drink in the future.

5. Take a chance. Many of the best beers I’ve ever purchased have been dice rolls when it came down to it. This does not need to happen as much as it did in the 1990s and 2000s—yes, I’m that old—because today, there are so many resources discussing so much beer from so many breweries. However, in some ways, this wealth information can be daunting, and even discouraging. If you’re afraid of looking ignorant … don’t be afraid. We’re all dreadfully ignorant about some things—so much so that there are things that we don’t even know that we don’t know. Do you know what I mean?

Anyway … if you are a curious person with a thirst for knowledge, you can dive in and become less and less ignorant, no matter your interest level in craft beer. Now, start getting that fresh, beautiful beer from that store or bar into your mouth.

Happy hunting!
