Ratio of water to PPMHRB

Migrated topic.

Hey everyone,

SWIM is about to begin extraction of MHRB. Before I address his question though, I would just like to say that I am very happy that I found this community forum! It is full of extremely useful information, is well organized, and more importantly seems to have a certain atmosphere that is both pleasant and mature, which I very much appreciate! :)

I was wondering if someone could help answer a question SWIM has regarding the ratio of water to pre-powdered MHRB, or perhaps direct me to a relevant post that I may have overlooked. SWIM is going to be using the Lazyman's STB Tek for his extraction. It is the general consensus that for every 1 gram of MHRB, 15ml of water must be used. However, I've heard people mention through various posts that when the root bark is pre-powdered, much more water must be used. Is this true, and if it is, what would the new ratio be?

Any answers would be welcome!

You might want to give a look at Noman's Tek too.
Noman's Tek

It is essentially the same as lazyman's with the difference being a freeze precipitation at the end, and ALOT more detail.
He suggests 1.5-2x the water normally used (22-30mL).

I'm giving the tek a try this weekend am planning on using 25mL per gram. This is just based on it being an easy number though.

I'm interested in more thoughts on this as well...

I have had no problems with the 15ml/g ratio with PP. I think you just need to make sure that your mix isn't too thick and has a decent pH (>13) - a thicker mix seems to make your pulling solvent less efficient plus along with a lower pH causes more chance of an emulsion forming.

However a side by side comparison of various ratios would soon clear it up - using the 1g/1g/15ml ratio as a standard baseline.

SWIM is doing this today with Noman's Tek.
He only has an iphone but the pictures should be OK.

Never done a STB with less/more water but have reduced the lye, with no emulsions and had the usual yield.

Maybe soft/ hard water has an impact. What type of water are you using?
