My beer iam fermenting which is now 7 days old has started producing a small amount of foam/bubbles on the surface! Everything else is spot on, just wondering if this is normal so near bottling stage? Please help
Follow up info: Starting gravity was 1.032. Temp has always been at 22 Celsius and the gravity is at 1.006 for second day now. No activity like yesterday as in small bubbles rising 2 surface.
