Pitching yeast

[garvinator70]

I tried the Muntons yeast it went real hard at first , woke this morning and the airlock has almost stopped completely . After one day , I have another high gravity that's been working for seven days US05 yeast . Should I go and get US05 and repitch this is going to be my best brew ever ! Thanks and cheers

You are making a mistake that too many brewers make: conflating airlock activity with fermentation. Take a gravity reading, then wait a couple days and take another one. If the gravity readings are identical, then fermentation has stopped. At that point you can decide if you need to take some action. I'll wager you won't need to.

Initial fermentation can go quickly. Nothing wrong with that in an average gravity beer. The higher gravity one is still going because there's a lot more fermentables for the yeast to consume.

OG for this beer is 1.051 FG should be around 1.014

I've gotten 1.05X beers down to 1.010 with regularity. But even FG1.012 is within range.

Ive had 1.050 beers ferment out in a couple days if temp is on the warm side. Usually finish in about 4 days at 68 but i also pitch huge starters.

How long after airlock stops should I check FG ?

 

[reefriot]

Check FG anytime. Then wait a day or two and check again. If it has stopped dropping. Cold crash and rack to keg or secondary and give it another week. Then keg. Or bottle right after cold crash

As a rule of thumb, and this is admittedly unscientific, I always wait at least one week before checking gravity. More often, I will wait two weeks, take a reading and wait a couple more days, then take another. Typically, at this point fermentation is complete and the yeast has had time to clean up any off-flavors it may have created.

If you just brewed a couple days ago, in a likelihood the CO2 is simply finding another route to escape instead of through your airlock. (Tip: make sure your airlock isn't clogged.)

I wait two weeks after it starts fermenting to take an FG reading to see where it's at. When the rapid bubbling slows or stops,it only tells me that initial fermentation is complete. Then I allow 3-7 days for the yeast to clean up by products of fermentation & settle out clear or slightly misty. Then prime & bottle.

Thanks for all the great replies , I'm gonna cross my fingers and wait 7 days
And take a gravity reading . Thanks and cheers
