This my first attempt at homebrew....My first Kit is a Coopers Draught
Fermentation went smoothly and lasted 7 days, I had a quick taste as I was transferring to the Beer Sphere. It smelled nice and tasted like beer, not vinegar phew

I am assuming the flavour will develop over the next four weeks
I am using a Hambilton Bard Beer Sphere for secondary fermentation which I started on Monday night, again all ran smoothly.
Here's where my problems have started....despite doing a pressure test with water and Co2 before filling with my beer and smearing with a ton of Vaseline I developed a leak around the tap tonight. I tried turning the tap hoping the nut would grip and tighten but it actually made it worse

In the end I had no choice but to take the cap off and with very clean hands tighten the tap nut. Really annoying thing is that I had really good pressure in the barrel.
Do you guys think the brew will be OK and should I still be able to build up enough natural Co2? That is assuming I don't spring anymore leaks but I not to hopeful on that front.
One thing I did notice was white blobs starting to float to the top when I had the lid off, is this the norm??
Cheers
