Please share what the 123 rule is.
thanks
The 1-2-3 rule is really a (somewhat faulty) rule of thumb that many newer brewers subscribe in...it means 1 week in Primary, 2 in secondary, and three in the bottle...but it is only a rule of thumb and it has several "flaws".
First one, is the simple fact that
https://www.homebrewtalk.com/f39/fermentation-can-take-24-72-hrs-show-visible-signs-43635/, which means that if you just rack your beer after a week,
you may only be getting 4 days of actual fermentation, and move the beer before it is truly done fermenting. (That's why you really should take a hydrometer reading on the 7th and 10th day and see if the fermentation has stopped)
Or wait 14 days, THEN rack to a secondary vessel for the 2 weeks...this will insure fermentation is complete.....
Secondly many people have noticed that leaving a beer 3-4 weeks in primary, skipping secondary and going right to bottle,
actually improves their beer. In fact even John Plamer says in How To Brew;
Leaving an ale beer in the primary fermentor for a total of 2-3 weeks (instead of just the one week most canned kits recommend), will provide time for the conditioning reactions and improve the beer. This extra time will also let more sediment settle out before bottling, resulting in a clearer beer and easier pouring. And, three weeks in the primary fermentor is usually not enough time for off-flavors to occur.
And finally like I mentioned above...bottle conditioning and carbing is not a standard thing....Gravity and Temp play a lot into the time it takes for a beer to carb and condition. And three weeks is just a snapshot for low to normal grav beers when stored at 70 degrees...a few degrees cooler, and it will take longer...I think Flyangler posted somewhere that it's one week for every 10 grav points above 1.050....
So the 1-2-3 rule is just another suggested way of doing things...but it does has a few flaws....
The only way really that you should decide to secondary (if you use one) or when to bottle, is with your hydrometer....and with bottling, waiting a minimum of 3 weeks before cracking them.....
Your beers will thank you for that.
