Something has happened that has never happened before

[Spooneys regular]

So, I thought I'd have a go at a wherry. First time doing this kit, stuck it on last Sunday and took a hydrometer reading tonight.
What happened in the trial jar was something I've never come across before. I got a creamy head I did put 500g dextrose with it.
Settled down and I could take a reading but I've only ever got the usual few bubbles. Was cloudy but tasted ok, any thoughts/experience appreciated

Thats just the amount of co2 thats suspended in the brew releasing when you filled the trial jar.
Now we are getting to the colder months, unless you have temperature control for your fermenters, the fermantation takes a little longer, so you may well have tested your brew at an earlier stage of fermentation than previous brew.

Got it sat in the brew fridge at 18/20 degrees. Make dozens of kits over the last few years just haven't seen this before
