I dont mean to seem ignorant, but whats the point? I can see the value of a tin, the value of a FWK, but the one in the middle?
The idea is that you get something as easy to use as a fresh wort kit, and in theory almost as good quality, but it is able to be shipped much more easily as it's less than a third of the size. Unlike regular kits these don't need to be dissolved and you can top up with water at the appropriate temperature and pitch straight away.
That's the theory anyway. I think if they actually tasted good they'd be perfect.
But they don't.
I've tried the Ezybrew JSAA clone and the Ezybrew LCPA clone and both were DISGUSTING. I may have had bad luck with both but I doubt it. These were way worse than a coopers supermarket tin of goop and white sugar.
I will not use them ever gain.
But I do see the point of the theory behind them.
I've also had bad luck with fresh wort kits to be honest. Plus they always seem way too week. They say 15L topped up to 20L with water but I reckon most would be better off kept to 15L.
I've tried two fresh wort kits and neither were as good as the partial mashes or extract + steep brews I've done.
EDIT: Just to explain better, if these things did taste 'almost as good' as doing your own partials they'd be great. You could store heaps of them in your fridge or wherever and just open and use them when needed. They'd be the ultimate convenience brew. You could not honestly find something more convenient. Even if your tap water is hot in summer you could cool the kit down to fridge temps and work it out so that the combined liquid was 18 degrees. Obviously not for the real 'brewer' that things pitching the yeast is the last step in brewing, but great for the type of people that'd normally buy kits or fresh wort kits.
I can't think of a more convenient way to make home brew personally. I hope another company takes the concept and makes a better result (if it's actually possible).
