Started my first ever brew last Sunday, using a Coopers starter kit with bottles and a Coopers English Bitter Kit. All seems to be going OK; it took a day or so for the airlock to start bubbling and by Wednesday was bubbling ever 12-ish seconds, now on Friday it's about every 30 seconds. Any thoughts if I can use the rate of bubbles as an indication as to when I should start using the hydrometer?
It's been between 22-26 degrees all week, except for the first couple of hours when I pitched the yeast at about 14 degrees before panicking and putting a brew belt on it. Anoyingly I didn't take the first hydrometer reading before fermentation, but reading the instructions it should have been about 1040 I think (using the 1kg of brewing sugar provided).
So, anyway, today I took my first reading using the hydrometer - 1012, so I think a little more time might be needed - I'm guessing something around 1008 might be OK. Will take another reading tomorrow to see what is happening... After taking the reading I couldn't resist drinking the contents of the hydrometer test tube, which tasted kind of like beer!

Looking forward to taking the next reading tomorrow and another sneaky taste...
