My Nut Brown Ale brew is 2 days old now and bubbling in the airlock has slowed down. Bubbling began after about 12 hours. There was probably a 1 cm width of foam, which has now recessed in which there is now a thin layer of some brown slimy looking stuff. First off, is this all normal. Second, am I supposed to be expecting more foam? The temperature has been around 72 this too warm? Thanks, Luke

You're fine, nothing you described is out of the ordinary. The foam and "slimy stuff" is krausen, the amount of which depends on a wide variety of factors. You're understandably nervous about what I assume is your first brew, but try to relax and trust the yeast to do their job: they are quite good at it.

I like to ferment ales in the mid-sixties, but 72 is not terribly high. I've made wonderful beers at similar temps.

its gonna look scummy for a bit....let it ride out and give it a week to ten days before you do ANYTHING. At that point take a hydrometer reading(sanatize first) and then take one a few days later and compare. If they are the same then ur done primary...if not let it sit a bit longer.

You might want to do some research on using a blow off tube. For me about 25% of my brews REALLY blow off some good size slim so I always insert a blow off tube for a few days before I put on an airlock.

Every batch is different and you will see all sorts of crazy things with the krausen.

Yep, totally normal. Here's a blowoff tube setup I rigged up.
