Decline in Gravity?

[2nd-Gen_Brewer]

Hi there,

I'm on my 4th brew. It's a Coopers Draught with 1kg raw sugar.

I didn't stir the yeast through, just sprinkled it on top.

When I sealed the lid, I took an OG reading of 1.038. This was yesterday morning. A little over 24 hours (approx 30 hours) later, I've taken another reading, and it was 1.042-1.044. Is it possible for it to decline like this? Or could the original reading be wrong somehow?

The most likely reason I can think of was your primary reading was off. If your Doug an extract batch you might not have gotten all the extract thoroughly mixed in the sample you took. Then after it sat for 30hrs you had a better dilution of extract in your wort. Just my .02

The OG reading should have been prior to pitching the yeast. Either way, getting a higher reading is not a decline, it's and increase in OG and most likely your first reading was off. As the beer ferments the number will go down, not up.

Assuming an all extract batch your OG should be the same as the recipe's predicted OG based upon the ingredients. It is just about impossible to miss unless you totally screw up the actual volume of wort.
