Thanks to a mix-up at bottling time yesterday, the 31 mixed bottles only have 50% of the priming sugar that they should, and today I corrected that by cracking some of the bottles open again and adding the last of my carbonation drops. The 31 bottles of Mangrove Jack’s Strawberry & Peach Cider now look like this:
- 10 metallic red crown caps: 85g of dextrose per 17 litre batch, so around 2.5g per bottle – roughly 50% of what’s appropriate. I left these alone from yesterday because I’m curious to see how ‘flat’ they are, and because I’ve never diddled with recently capped bottles and need an insurance policy.
- 11 clear flip-tops: same 2.5g from batch priming, plus one Fox’s carbonation drop. Two of these are recommended for a 500 ml bottle and together they weight in a smidge over 5g, so these flip-tops should be perfectly carbed.
- 10 non-metallic red crown caps: these also have 2.5g per bottle from yesterday, but to each I added one Cooper’s carbonation drop, aimed at 375ml and weighing in at 3.04g. This means the non-metallic red crown caps are technically over-carbed by 10% but I don’t expect it’ll make much difference – in truth I used the Cooper’s drops because I’d run out of Fox’s.
Looking back over the process of re-opening these I don’t think there’s very much to worry about. Each bottle was treated to a good dose of sanitiser before I popped the cap, and as soon as I did so I dropped in a carbonation drop and added a fresh, sanitised crown cap – or flipped shut the still wet flip-top. I did the flip-tops first and noticed that adding in the carbonation drop resulted in a fair bit of fizz, but because the flip-top was within reach I was able to cap it before anything boiled over. The first couple of crown caps I treated subsequently did eject some foam, but then I nailed the procedure and the rest were OK. No spinners or obviously leaky caps.
All 31 bottles were moved to the server room which is bouncing between 21 and 25 ℃ depending on the amount of sunshine that day. In around a week’s time I’ll put these out to the garage for conditioning.
#wisdom: ending with a positive, and I hear that cider isn’t too bothered about oxygen since it’s the hop oils in beer which cause oxidisation when exposed, so unless it’s a dry-hopped cider there’s nothing to worry about. Oh well, was fun playing with the beer gun all the same.
