It's basically a judgment call that you need to make, on whether it's "close enough". If enough sugar is available, some yeast cells, such as Saccharomyces cerevisiae , prefer fermentation to aerobic respiration even when oxygen is abundant. Fermentation is a natural process. Drew Horton, Enology Specialist Matthew Clark, Assistant Professor 10/6/2016 Each wine harvest season as the picking ends and the last wines are completing primary yeast fermentation, it is often asked about how to know when your secondary or "malolactic" fermentation has completed? If you used a recipe kit then this information will often be listed in the instructions for reference. If you take successive readings days or weeks apart and they all show the same value, then your wine fermentation is finished. The yeast then starts “eating” the sugar in the dough and off-gassing alcohol: that’s fermentation. An interesting article!

Fortunately, there are many visual signals and measurements that can be taken to ensure that your primary fermentation is done and ready to move to the next step.

Ideally secondary should occur when fermentation is COMPLETE and at a colder temperature than the primary ferment. The frothing results from the evolution of carbon dioxide gas. Most homebrewers bottle their early batches of beer and may wonder what carbonation drops are, how they compare to sugar, and how to use them. I found this out when I first took the brave step of risking a reasonable amount of home-grown fruit for a chance of making something equally tasty. If the SG dips below 1.010 in the primary fermenter I’ll wait it out and let fermentation complete where it is. text-shadow: 1px 1px #c42d22; /* It is an anaerobic reaction, which means it requires no oxygen to be present other than the oxygen atoms contained in the sugar. When fermentation is nearly complete, most of the yeast will settle to the bottom of the fermenter. Bottle it, enjoy it, and start the next batch! After a certain amount of time, the yeast inside the beer will start to die off in a process called autolysis which essentially means ‘self-destruction.’ The yeast cells burst apart when they die and the contents released can contribute to several off-flavors, none of which are pleasant. Grape juice becomes wine as the fermentation process is complete. The frothing results from the evolution of carbon dioxide gas. Stuck Fermentation. While it doesn’t always tell you when your fermentation is complete, it will give a fairly reliable indication that it is not complete, and in my view, it deserves mention for this reason alone. For instance, if the OG reading is 1.092 and the FG is 0.99, the math goes like this: (1.092-.99) x 131 = 13.36% ABV. Primary fermentation includes a period of active fermentation that lasts about 48-72 hours and is considered done when hydrometer readings are stable. The color of the beer can brighten as it becomes clearer. From what I’ve observed, amateur winemakers seem far less concerned about temperature control than their beer brewing counterparts. When complete, practically all of these sugars have been consumed. Also, when fermentation is complete, yeast has a built-in defense mechanism wherein it forms a thin skin over the surface of the beer protecting it from O2 contamination. */. So why risk it? Here are visual signs that fermentation is complete: I should point out that even though these clues are very helpful, they are not the determining factor on whether or not primary fermentation is complete. * The yeast can be reused a number of times before it needs to be replaced.

In the 1850s and 1860s, Louis Pasteur became the first zymurgist or scientist to study fermentation when he demonstrated fermentation was caused by living cells.

I would suggest waiting several days, or even a week between readings, especially after the initial bulk of wine fermentation has finished. Part of the difficulty in answering the question is that home fermentation is often done with the intention of keeping the food "alive" even when it is consumed, which means fermentation will still be ongoing. The only way to make sure fermentation is complete is by checking the gravity. To truly know the answer to that question, you will need to take some hydrometer samples and check the measurements. (Avoiding Skunk). There may be some instances where you think that fermentation activity has stopped but the finishing gravity is too high. Once fermentation is complete, you can remove half of the liquid and replace the liquid removed with raw apple cider vinegar before placing it in the fridge.
