I tried my first brew using a Coopers' kit, and I'm now at day 7 in bottles, waiting for my new kit and Irish Stout Package (tomorrow delivery if their lil map is correct). I had zero problems with my tap, but being an ol' farmhand, I twisted the seal as I inserted it, knowing that always cuts down on rubber damage on seals. I didn't lube because I was afraid of contaminants. I plan on brewing off both the starter Lager kit and the Irish, and I'll let ya'all know how things go. I'm pretty sure that the 1st toss will be gone in time to re-use the bottles. Interesting thing...Coopers' is out of bottles, but they've discounted the kits...maybe it's worth it to buy kits for bottles? hahaha! That way, you have more in the pipeline..haha anyway, I'm going to check for alternatives to purchase bottles, even tho I eventually want to have about 4 of the kits to run my pipeline. I drink about 2 cases of "bought beer" per week, and then I have a Bro who drinks as much or more than I...we down a bit of beer, especially after it gets into Spring and warmer. My Wifey is always amazed that we're never drunk..I just tell her that you "rent beer, not own it. It's pis...passed thru before you can get a buzz off of it." She just rolls her eyes.
