A blind tasting removes the bottle, the label, the pour colour and the price before your tongue does any work, and the reason to bother is that expectation is doing more of the judging than most people realize. You already know an imperial stout will be dark and heavy before you taste it, and a session lager will be thin, and that prior sets a default your palate then tends to confirm. Blinding the beers is the only way to find out what you actually think of the liquid. It is a method rather than a party trick, though, and it has costs and failure modes of its own, so the version worth running is the one designed to stop you fooling yourself at the end.
This is different from the general subject of running a structured tasting at home, which this site covers separately with beer tasting worksheets, and from the matter of building a vocabulary, which is covered in our guide to training a tasting palate. What follows is the blinding step itself, what it actually takes away, and the ways a blind result gets misread, which is the part most people skip and the part that decides whether the exercise was worth doing.
What Blinding Actually Removes
The label is the big one. Words on a bottle, such as a style name, an alcohol figure, a hop variety, a barrel age or an award, set an expectation, and that expectation measurably shifts which flavours you report. The effect is strongest for styles carrying a strong prior, meaning a hazy pale ale you are told is hazy, a sour you are told is sour, or a high-alcohol beer you are told is strong, because the prior and the flavour line up and the prior is doing the work. A second, subtler removal is social, because the pourer usually knows what is in the glass and their face, their phrasing and the order they serve things in are all information. That is why the person pouring and the person tasting should not be the same person wherever you can arrange it.
Blinding also takes away the things you cannot get back. Colour, clarity, head behaviour, the way a beer looks in the glass and how the head sits and holds are all real quality signals, and a blind round throws all of them out. A hazy beer and a clear beer of the same style become hard to tell apart, and a badly handled beer with a poor head can be outstanding. So a blind round is a statement about flavour and it is not a verdict on the beer as a whole, which is worth holding onto before you start, because the temptation to treat a blind ranking as the final word is the most common way people misuse the method.
How To Blind Without Ruining It
Keep it small, because the whole logic rests on your attention still working at the end. Three or four beers is the useful number, and a fifth is usually one too many, since palate fatigue and the dulling effect of alcohol both creep in and start rewriting your earlier notes. Pour them all into identical, numbered glasses, and get the packaging out of sight entirely rather than just face down, because a shape in the dark is still a clue. If you have no opaque bags, a cardboard box with holes cut in the bottom and the numbers written on the outside works, and numbered slips of paper over the top of each glass defeat a good deal of visual information on their own.
Hold everything else constant, or you have introduced the very variables you were trying to isolate. Same glass, same volume, same temperature, the same minute poured, and poured by somebody who does not know the order as far as the tasters are concerned. Serve in an order chosen to avoid a heavy beer immediately before a delicate one, and put plain water and something neutral to eat within reach, because without a palate cleanser between glasses the second beer inherits the first one's residue and you will read that as its character. Give each taster a sheet with the numbers down one side and space to write before they see anybody else's.
Reading Your Own Results Without Fooling Yourself
This is where blind tastings most often go wrong, and the problem is not the blinding, it is that people are not honest about what their own results mean. Write every note before you see anyone else's and before you know any reveal, because the moment somebody else says they got grapefruit in glass two, your glass two has grapefruit in it whether it did before or not. Rank the glasses before the reveal, not after, since a ranking made once you know what was in them is contaminated even if you were trying not to let it be. And decide your verdict while the beer is still in front of you, because a glass you have to think hard about is telling you something about your own palate on the day, not about the liquid.
Be suspicious of the first three seconds. Your palate gives an immediate impression on any sip and then revises it, and which impression you end up reporting depends on how fast you swallowed and how much you trusted the first hit. A beer that seems flat in the first instant frequently turns out to be understated, and a beer that jumps out immediately sometimes just has a loud early aroma. Suck it in rather than drinking straight down, let it sit on the tongue, and give each glass a genuine second look. The single most common error in a blind round is writing down the first impression, which is usually a report on your own reflexes rather than on the beer.
What A Blind Result Actually Means
- It is a measurement of your own palate on that day, under those conditions, and not a measurement of the beer's quality, so a blind result that disagrees with the sighted version is normal and not a mistake.
- It covers flavour, not appearance, so never let a blind ranking decide how a beer looks or how well its head holds, because that information was deliberately removed.
- It is a statement about this beer against these others today, not about the brewery or the style, and a beer that wins blind among cheap pale ales may lose badly among a mixed set of stronger ones.
- It is worth repeating before you believe it, since re-running the same set of beers blind a week later is the cheapest way to find out whether your notes were about the beer or about the evening.
- It should never be run by the person who also picks the lineup and pours it, because that person carries all three sets of information and cannot un-know any of them.
Frequently Asked Questions
Is a blind tasting actually more accurate than a normal one?
It is more accurate about one thing, which is your own reaction, and no more accurate than a normal one about the beer. Blinding genuinely removes a source of bias rather than the bias itself, so it gives you a cleaner read on what you actually like once price, label and reputation are out of the way. It gives you nothing at all about appearance, and it introduces a new source of error in that you are working from a shorter, colder, more abstract impression than usual. The two approaches answer different questions, which is why the most useful routine is to run the same set blind first and then again sighted and compare.
How many beers can I judge reliably blind?
Three or four, and the reason is attention rather than a rule anyone set. Each glass takes real concentration if you are going to look at it twice, and the later glasses in a longer set get judged against your own fatigue and against the alcohol already in you, which is exactly the state in which your first impression is most likely to be mistaken for a real opinion. If you have eight beers, split them into two rounds of four with a gap between, or run two sessions on different days, and write the results up before you start the second set.
Should I know the style before the reveal?
No, and this is the part that usually gets abandoned. Telling people the style mid-round, even casually, even just to help them, undoes the thing the exercise was for, because the style is the label in another form and it carries the same prior. If you must know, know it afterwards and write your notes down first, then see whether knowing the style changed your opinion of the same glass. That comparison, blind score against sighted score, is more informative than either number on its own and it is the part of a blind tasting most people never do.
Run It Twice And Change One Thing
The blind round is worth doing twice, once blind and once sighted with the same beers in the same order, and comparing the two sheets afterwards is where the real information sits. Where the rankings agree you have probably found something real about your palate. Where the sighted version is much kinder than the blind one, the label and the reputation were carrying the beer for you. Where the blind version is kinder, you have a beer you should be buying more of and are probably not, because you have never been persuaded by it. Write the sheets down, keep them, and the comparison stays useful long after the glasses are washed.
