Just checked the notes and both beers stuck at 1.020 - but don't worry because both of the kits were out of date and I short brewed them to 3 gallons. I got 28 beer kits for £1.25 and a lot of them were out of date and even with new yeast quite a few of them stuck at 1.020, especially if I was using S-04.
I got both beers going again by aerating the hell out of them. I really don't think you'll need to. Loads of the kits tasted weird, metallic like putting coins in your mouth. I used to meddle and poke at things back then much more than now and I think I oxidised loads of the beers. Now because I don't tit about so much I bet I've had the snakes happen and never even knew about it.
This is further notes on the one I turned into a Christmas ale that everybody really liked, my mate Athos adored it.
⦁ 14th 1:25am As well as 5g each of cascade I added a boiled up mix of marmalade, mixed spice, lemon zest and a cinammon stick to one DJ and 2 cardamom pods, some raisins and cinnamon stick to the other. The raisin mix was really sweet and I liked it. I've no idea if any of these will give any flavour to the brews and maybe they'll be completely destroyed by the cascade which is why I limited it to 5g each. Think I'll have to gelatine these babies. It's worked incredibly well with the Trad English.
⦁ 16th 15:30 tasted them both and the one with raisins definitely had a hint of something and I'm leaving that alone. It seems good. The raisins are so bloated and scary looking, like they'll ruin the brew. The marmalade and spice one doesn't seem to have anything but the cascade so I'm thinking of beefing that one up with the same things.
⦁ 17th ~ 10pm - I added a load more marmalade, mixed spice, cinammon, an all-spice berry and 2 cardomom pods to the one that wasn't very tasty. By the 19th the taste was punchy with maybe too much cardamom.
Looking at the testing notes 47 days after bottling one I said could be a commercial beer 8/10.
