I Hate Caffeine

Apparently if you steep a teabag in 8oz of water you get more caffeine in the brew than if you steep it in 6oz of water.  Source  If I understood the scientific paper I may be able to understand why if you add more water the caffeine increases instead of being diluted.

I'm not having a brilliant morning.  I feel the urge to knit and the shrug I have been knitting (216 stitches on 3.75mm needles or US size 5) was nearing the end.  I was getting all giddy last night as I started the final welt and then the circular needle broke.  I am going to fossick out another project, I really could do with some knitting.  Another needle is on order, and this time I've gritted my teeth and spent a little more in the hope it will last.

Bear woke me up when he realised that his dressing had come off in his sleep.  I was half way through before I realised I hadn't got my glasses on.  I'm not at my best when woken (and without caffeine) and I'm not confident.  Dispassionately, I am putting a square of dressing and some sticky tape over a wound that is clean, dry and looking more like a cut.  Bear is healing up really well, despite my nerves with the dressing.  The nurse gave us three spare ones, and I expect to put the last one on some time tomorrow.

I've started off the day out of sorts and all the things that I would normally choose as a calming tactic have dratted caffeine in.  That is, tea, diet cola or chocolate.  Yes, chocolate contains caffeine, darn it, at least good chocolate does.

I am going to try and cut down on the caffeine slowly as some time with Google says that the withdrawal can be harsh, especially for a heavy user like myself.  This would be easier if I could work out how much caffeine there is in a teabag.

  1. Very glad to hear Bear's wound is healing nicely.

    So sorry to hear your circular knitting needle broke. Glad you have ordered yourself a new one.

    Looks like the standard answer for caffeine in tea is 26 mg. of caffeine in an 8 oz. cup of tea. I got the same amount when I searched for caffeine in a tea bag. One site (Mayo Clinic) gave a range of 14-70 mg in an 8 oz. cup of black tea (probably depends on how long it is steeped, although they didn't say). They also say that up to 400 mg of caffeine is OK for a healthy adult.

  2. I went back and read the paper you linked. I think the simple explanation for more caffeine in 8 oz. than in 6 oz. is because there's more tea by volume (and thus more caffeine) in 8 oz. than in 6 oz. On the 3rd page of the paper, towards the end, they do say that the amount of caffeine per ounce is more or less the same in the 8 oz. and 6 oz. cups. Hope that helps.
