Default Using Caffeine

I am presently working on a beer that I would like to add a caffeine kick to. I've read some of the other threads. This is not a coffee beer.

This is a Scottish Ale. I'm looking to use a liquid form of Caffeine. This product has been suggested.

http://www.energyfiend.com/caffeine-...affeine-liquid

If anyone has tried this could you please give me your input. If not any input would be appreciated. This is suppose to be less bitter in liquid form. I plan on adding it after racking. I want something that will give almost a Red Bull kick.

Any advice is welcomed.

Wow, that stuff looks scary and I am a major caffeine addict too. That said, I don't think it would be something that would mess up your beer if you are putting it in at the time of drinking it. If you put it in at bottling or before, it may cause some adverse reaction. That is the fun with experiments though! You'll be the expert after this. I would say adding it to some of your bottles at bottling would be smarter so you dont mess up a whole batch. But more power to you if you do the whole batch. I bet it will cause that much more anticipation.

Be careful. Caffeine is a controlled substance for a reason, it's actually the active ingredient in a lot of bug spray. In a large enough quantity it will make your heart explode, like the bugs.

I'd use Wake-Ups caffeine tablets, one or half a tablet per bottle (100mg or "equivalent to a cup of coffee"). I think it'd be too "risky" to mix it in the whole batch. LD50 is actually 150-200mg PER KG of mass so it probably won't happen but the lethal dose doesn't take into account genetic factors, predispositions or health priors.

Caffeine is not a controlled substance actually which is why you can readily buy caffeine pills, liquid, etc..

This is also pretty scary, have you ever had the need for 2lbs of 100% caffeine?

Research the quantity needed carefully before adding this stuff.
Caffeine is also bitter so you may have to adjust your hops down slightly.
Good Luck and keep us posted!

Coke zero has 45 mg/16 oz. Red bull has about 2x that much. Coffee comes in about 200 mg.
Just make sure you do the math right to get in that range.
For 5 gallons (640 oz) you'll need between 1800 and 8000 mg (1.8 - 8 g).
Caffeine is very soluble in water, so grinding up some No-Doz will work well. I don't know about the liquid you asked about, but No-Doz provides zero taste at the concentrations you are using.
Be careful.

Reason: clarified zero taste.

You are right I misspoke. What I meant to say is that its highly regulated to purchase pure caffeine, but after some quick searching I am wrong on that point too.

I am right about it being a highly dangerous and potential harmful substance in its pure form.

To the OP, why dont you just load up on some of these...I here they are delicious...

Woldn't it be easier to just take a no doze pill while drinking the beer?

Hm... this is making me want to try making a coca tea beer again...

And I'm intrigued by that 5150 stuff in general.
