I'm brewing my 1st kit which my gf got from a local hardware store (ironically there's a home brew store not 5 mins away sigh) but wasn't a cheap one.
Just need a bit of advise as there is a mountain of information out there and it's making my head spin.
WHAT IVE DONE
It's golden ale, 23 liters (5 gallons) came with two large tins with syrupy like mix in.
Iv'e added the yeast and left it at 20 degrees (68f) and it stopped fermenting after only 3 days, which i thought was odd. tested it with hydrometer and got a reading far short of what was required (22ish not close to 10) the So i added a packet of amylase enzyme to get it going again.
1 week later the fermenting has stopped, tested and carefully transferred to secondary.
After only 24 hrs i pulled some into a glass and it was carbonated with as expected a bitter yeasty taste as it still needs to mature.
WHAT THE QUESTIONS ARE
1) why after such a short time is the beer carbonated with no fermenting when it was flat before transfer to secondary? There are no visual signs of fermenting going on. Might my keg explode? it's good for 15 psi.
2) should i leave it 2 weeks (as suggested by some members and mico brewers) in the keg and then add my 5 ounces of primer and bottle or should i prime and bottle now?
Hope that is clear, thank you.
