How do you read a specific gravity beer?
Give it a spin to make sure it’s not sticking to the sides of the jar. Finally read the specific gravity or potential alcohol where the surface of the beer intersects.
What should my hydrometer read for beer?
Most hydrometers are calibrated to read at 20°C (68°F). Knowing the temperature of the wort is critical for reading the original gravity (OG). The best practice is to use the hydrometer when the wort or must temperature is 15°C – 59°F for lager or 20ºC – 68ºF for beer or wine.
When should I take gravity readings beer?
Gravity readings are typically taken before pitching the yeast and after visible signs of fermentation have ceased. It is generally not recommended to take more samples than necessary because each time the fermenter is opened to draw out wort, you are introducing the risk for contamination.
What should my beer final gravity be?
about 1.012
You can estimate the approximate finishing gravity of a beer by taking into account the attenuation rate of the yeast strain you are using. For example if you have a yeast with a 75% attenuation rate and your original gravity is 1.050 the estimated final gravity would be about 1.012.
Why is specific gravity important in beer?
Brewers will track the specific gravity (SG) for the duration of the process to make sure that the gravity levels remain consistent from one batch to the other and that no problems arise from the malt quality, brewing process or yeast productivity.

What is considered a high gravity beer?
“High-gravity” refers to brewing a beer with high original gravity (OG)—typically, above 1.075 OG is considered high. OG is a measure of the fermentable and un-fermentable substances in the wort before fermentation.
What is a good hydrometer reading?
Understand the measurement.
Pure water should give a reading of 1.000. A higher reading means the liquid is denser (heavier) than water, and a lower reading means it is lighter. The specific gravity of wort (called original gravity or OG by brewers) varies greatly.
How do I know when fermentation is done?
When exactly is it finished? Fermentation is finished when it ceases to off gas. The airlock is still and has reached equilibrium. If you brew in glass, look at the beer, the yeast ceases swimming and flocculates (settles) on the bottom.
When should I start checking final gravity?
Your final gravity (FG), which is taken just before packaging and before you add any priming sugar. Again, make sure you have adjusted for temperature if necessary.
What is a good starting gravity for beer?
1.030-1.060
The gravity measurement is most often done on a unitless scale that measures the relative density of the wort compared to water. So water would have a specific gravity of 1.000, and beers often start in the 1.030-1.060 range.
What does high gravity mean in beer?
Brewers take the gravity reading of the unfermented ingredients before adding yeast to them. That original gravity has a number like 1.061 or 1.080, and the higher the gravity, the higher the potential alcohol content of the beer.
How do I know my beer is done fermenting?
If there are still bubbles in the airlock after 14 days let it sit for another few days, or at least until there is no bubbling for at least a minute or two. Once there is no activity in the airlock, fermentation is complete.
How do I know if fermentation is complete?
Fermentation is finished when it ceases to off gas. The airlock is still and has reached equilibrium. If you brew in glass, look at the beer, the yeast ceases swimming and flocculates (settles) on the bottom. Pull a sample and taste it.
Do higher ABV beers take longer to ferment?
Not surprisingly, big beers take longer to ferment out and age.
What if my original gravity is too high?
If the gravity is too high, dilute it by adding boiled or sterile water: This time we’ll assume our target was 1.056 but we overshot and came in with a gravity of 1.064, again using a 5 gallon batch. We’ll use the fact that the number of points times volume should be a constant to do the dilution.

What is original gravity in beer?
An original gravity (OG) reading indicates the number of dissolved sugars in the beer that can be converted into alcohol. These sugars come from malted grain and are later consumed by yeast to convert wort into beer. In short, the OG is an indication of the beer’s potential alcohol percentage.
When should I stop fermenting my beer?
Yeast requires certain conditions for the fermentation to take place, and if those conditions aren’t met, the fermentation can stop well before it should. Most beers will finish at 1.020 or lower, so if your beer stops fermenting at 1.030 or higher, you may have a stuck beer fermentation.
Should you stir during fermentation?
You should not stir your homebrew during fermentation, in most cases, as it can contaminate the beer with outside bacteria, wild yeast, and oxygen which leads to off-flavors or spoilage.
How do I know fermentation is complete?
What should specific gravity be after fermentation?
If the post-fermentation gravity reading is at 1.000 or less, it is definitely done.
Why is my beer final gravity so low?
Low final-gravity readings can be caused by wild yeast contamination, bacterial contamination, or not enough dextrins. A careful examination of sanitation, brewing procedures, and yeast source can solve many final-gravity problems.
What is the highest gravity beer?
Dogfish Head High-Gravity Beers to Try
Called “the Holy Grail for hopheads,” this beer has 15-20% alcohol by volume (ABV) and balanced flavors of citrus, spice and caramel malt. The 120 Minute IPA goes well with smoked or grilled meats.
Can you let beer ferment too long?
Leaving beer in the fermenter for too long increases the chance of autolysis, a process in which the yeast cells’ vacuolar membranes disintegrate and release hydrolytic enzymes, causing the cells to burst open, releasing the content into your beer.
