Last week I brewed my first all grain brew on my new grainfather. During brew day I ran into a few problems, firstly the extension lead tripped on me once during the mash and twice during the boil. The main issue with this, is I was relying on the app for timings and had to guesstimate where I was when I reset everything. I have since bought 2 new extension leads which should be able to handle the load. Main issue was probably trying to run both the grainfather and the spare water heater through the one extension. Then during cooling the hose that I had attached to the out end of my thrumometer came off and straight into the wort. Some wort splashed over the lid and I foolishly in a panic poured this into wort. So contamination was also a worry. Anyway then I had an issue with fermentation temperature for the first 24 hours which I mentioned in an earlier post. So Today I decided to take an early gravity reading to see how it was getting on. The wort looked nice and clear and was reading 1.018. Initially it tasted very malty but fine, but then there was a bit of an acidic aftertaste, not terrible but noticable. I intend to leave it in the fermentor for at least another week but was wondering if anyone has any experience of something similar. Will this brew end up down the drain?
