I turn water into beer. That's pretty badass.

1 - as dcbrewing said, if it's good to drink it's good to brew.

2 - it's a blend of ale and lager yeasts. i find it works best at 16-18C. Unlike their ale yeasts which are hardy and will ferment a lot higher.

3 -  for the aztec gold recipe use any extra light DME (eg this . brew to 19-20 liters. again the mexican cerveza kit comes with the same lager/ale blend, so 16-18C would be best

Hi guys I've got the coopers lager kit too like martin but had the lager yeast. Its in its 3rd day of fermentation at 16-18 degrees. The instructions said between 21-28 but after some advice online from underdogbrewing (who steered me to this fine establishment too) I
brought it down to 16-18. Quick questions....Do i still remove the Kreuzen after 4 days at the lower temp ? As a rule , how long should i ferment the lager at this lower temp ? Thank you in advance guys!

LordEoin

As a rule, ignore fixed timeframes. They'll only make you rush the job. Instead observe the brew and let it tell you when it's ready.
By the kreuzen, i presume you have a coopers fermenter and you're referring to the krausen collar, right?
You remove this when the level of the krausen (the foam) drops below the ring of dark bitter scum stuck to the collar.
Just remove the lid, take out the collar, replace the lid.
Any shorter and you'll just get a krausen ring on the fermenter. Any longer and you might not have as much of a blanket of protective co2 over the beer.
Coopers kits usually ferment out in about 5-7 days(pilsner takes longer). You'll know when it's ready because the krausen will disappear and more yeast will to drop out.
Take a hydrometer reading when you think it's done, then another 2 days later. If they read the same then the fermentation is finished.
You can prime and bottle at this stage if you want. many people will leave it another week to let the yeast 'clean up after itself'.

I was just going to ask the same collar question :) Thanks Eoin!

yeah, that collar's a bit of a weird one. Its purpose is to give enough headspace for more violent brews and once the krausen has died down removing it makes the headspace smaller and removed the krausen ring while its still soft and easy to clean.
They're a very well designed FV, right down to the tap and the bulged bottom for sediment:)

- My first brew will be good to bottle soon, so Eoin, would you advise to leave the brew in the fermenter for another week or rather bottle when's ready? I guess leaving the beer to rest for another week won't do the brew any harm, right? Just for me to understand the process for my future brews - what are the advantages / disadvantages of doing so? Many thanks in advance!
