GSI Java Drip



The perfect gadget for the weight conscious coffee connoisseur… on a bike

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

What the scores mean

Good scores are more common than bad, because fortunately good products are more common than bad.

GSI's Java Drip is  gadget for camping cycle tourists with an uncompromising caffeine addiction, the Java Drip promises fresh filter coffee without a weight penalty or palaver. Weighing only 12g, it fastens onto your mug with three plastic legs/clips, and then the dose of ground coffee is placed in the mesh followed by hot water. It then simply drips through, as the name suggests, and can easily be cleaned out afterwards. The result is a perfectly acceptable brew, far more enjoyable than the instant granules that are normally the only option of the weight conscious tourist. Of course you have to carry the ground coffee too, but 12g extra weight in the form of the filter isn't a lot by anyone's measure, and it takes up next to no space either.


The perfect gadget for the weight conscious coffee connoisseur.

Ah! Just realized, i should have said my problem was "badly brewed coffee with too-cool hot water, eg 80 degrees" - cold-brewed is actually pretty good! (I make it occasionally, requires a long infusion time - overnight is good - and is v popular in Japan).

For anyone who doubts you can have good coffee when cycle camping, here's my setup:

I am jealous of that set up I could not be bothered when camping. However I 'slum' it with coffee bags. Individually foil sealed and can be dunked and stirred around like builders tea for a hot cup of java!
And the aroma is there too...  105

Cold-brewed coffee anyone

I recently was exposed to the delights of "sun jar coffee". I'll pass.

I've used one of these in the field many times, not this exact one but a very similar beast. and the coffee it made was absolutely fine for my uncultured pallette.

I have a slight suspicion that you're a bit more of a perfectionist than many PJ.  1

Cold-brewed coffee anyone? Seriously, if I'd taken that with me cycle touring (in Ireland), the result would have been pretty sour and underextracted. Water won't stay at 92 degrees for long in that thing!

I favour an Aeropress in the pannier instead. (And a hand grinder. Nothing beats grinding away in a field at dawn, before you hit the road. Unless MTB's your thing, in which case you can keep grinding away all day).
