Fermzilla

Hi all, just put down my first brew in my xmas present (fermzilla). What is the best way to get an original gravity ?????

 

[Skillz]

Hydrometer or refractometer
You will need a hydrometer for the FG.

I meant how do i get some brew to test ?

I think he may be referring to how to get a sample out of the Fermzilla to take an OG. Gas it up and take a sample through a picnic tap.

Lol, completely blanked on that part

How accurate will the reading be if i do one now ? Been in fermzilla for 36 hours.

Accuracy is to do with the instrument. But is not ultimately important what you’re looking for is an indication that fermentation is slowing or stopped. After 36 hrs it’s unlikely unless you’re using a sounding valve

What i'm getting at is, without an original gravity reading, when fermentation has ceased & ready to keg, is there another way of working out the alcohol content ?

You can probably work out your og from the recipe you used. Then take a final reading to tell you the abv. What was your recipe?

Will try & upload a pic of the recipe i put on my brew tracker app.

If after 36 hours it is kind of pointless taking a sample to find opening gravity. At that stage I have a nice healthy krausen and the brew has probably dropped 10 points. You need to take a sample before or just after you pitch your yeast. The best will be an estimate from the recipe, like Ferment 8 said.
I draw a sample by disconnecting the blow off letting the fermentor build up some pressure, and plug in a picnic tap.
