How best to clean bag after pressing? How many pressings can a bag do before it needs replacing?

Hi Michael, bags can be washed by hand or tossed into washing machine (no soap). I like to invert them and take outside first and give a good shake which saves quite a bit on the scrubbing. Bags can get holes in them pretty quickly unless you follow directions to repack. I actually prefer using unbleached cheesecloth which is inexpensive and more porous and can be discarded after using a couple of times, or especially if using for oils. check my blog on the subject https://blog.strictlymedicinalseeds.com/pressing-herbal-tinctures-lessons-learned-and-questions-answered/

Hi Richo,
While pressing a fresh echinacea root & flower/leaf glycerite tonight in the press with this bag, it still felt quite heavy and my yield was smaller than I expected (3 cups finished). There was around 1/2 gallon in the bag and I pressed slowly. Is that just the nature of pressing a glycerite? I wondered if I should have used cheesecloth instead. Thank you very much!

hi kris10.ann, thank you for writing. glycerine is thick and i do think you’re right, the cheesecloth should work better, and warm the whole thing up before pressing–cold glycerin is extra thick. i generally use the pressing bags for dry herb tinctures and opt for the cheesecloth with oils and fresh herb glycerites. I suppose you pulled everything apart and kneaded the marc, right? I do that anyway with every pressing to help prohibit the whole thing from getting stuck and to optimize yields. Another thing to consider is to use the pressing block and just press less with each pressing–do a quart instead of a half gallon–that will increase surface area to mass ratio which helps. richo

Very helpful as always. Thank you! I didn’t think to warm it up before straining, and I’m up in Ohio, so that definitely would have helped. I’ll remember for next time! I didn’t knead the marc. Can you explain that? Do you do that after a first pressing?
Thank you again. I really love supporting your business, not just because of the quality, but because of how generous you are with your help before and after purchases.

hi kris10ann, no prob, my pleasure. The kneading thing is demo’d in the oldest youtube tincture pressing, the one where i look. . . youngest. anyhow in short you press until the point of diminishing returns, then let the press down and take the pan out and pull out the bag with the semi-dry marc in it and work everything around in there, then repack into the press and you’ll get another yield of tincture. This works because when pressing, the outer layer of the marc becomes quite dry and the inner portion stays quite wet. So you mix it up and repress. This also helps keep the press from getting stuck, because the reason it gets stuck is the bag rides up around the plunger. Once that starts to happen, it is a good idea to bring it down and repack. richo

Do you have bags that are any smaller than 1/2 gallon?

Lydia –
How do you clean the pressing bag? Especially thinking of cleaning the bag after an herbal oil pressing. Does it make sense to have one bag for pressing oils and a different one for tincture & succus? Thanks

Hello Lydia,
Once you use a bag for oils, it is an oil bag forever! For standard tinctures, empty out the marc and shake the bag, then wash by machine or by hand. Don’t use soap. Remember that you can just use 4 layers of cheesecloth to press out your oils. Cheesecloth really works better for oils than the pressing bag, and can be discarded after use.
