Thanks for confirming... That's what i thought, i have a few 30ml bottles of juice steeping right now that I bought and I'm hoping that cool dark place with hand shaking would be enough.
The only other reason i can think of for having a "shaker" for small batches is if there's not much space in the bottle to shake( 30ml juice in a 30ml bottle can get a little difficult to mix considering the liquid doesn't have much space to move around).
Yup.. that's another point that I forgot to mention... the space within the bottle limits the way the liquid gets mixed...
As you're just starting, it's fine to shake and get the general idea.. but the day that you do over a dozen bottles and see how much of a pain it is to shake them all, and then again for about a week (as the shaking simply doesn't do a good job), you'll be looking up milk frothers or similar, fairly fast..
