this is my favourite way of storing shrooms, first dry them thoroughly, then get your favourite large bottle of alcohol, i use rum and vodka. then fill the bottle with the shrooms. the vodka goes fluro blue, its a mad cool looking drink...the rum goes totally dark purple almost black.
sometimes, if i have heaps, or just want it to be mad strong i put say somewhere between 100- 200 or more dry grams in it, to do this you will need to grind them, as they swell to near original size........ and when you dose you only need one small shot,...this bottle is for storage over a long time, not for drinking in a weekend!!!
other times, most often now as this has become my way of ingesting, i put 10 - 30 dry grams in, as i like to have a few drinks that night etc,if there is 10 gm in there i know i can drink half a bottle no worries.......i prefer about 30 gm abottle tho... i dont grind these ones, they swell in the liquid and at the end of the bottle you can tip them out and eat em too...or just leave em as the residual alcohol stops rot and mold etc
any way cuz they are in alcohol, you can store them for years, decades i guess..why i dunno, but having a mega strong bottle of top shelf on the bar is enticing..
there are far more complicated ways of using alcohols to extract, and then purify and eventual crystalize, which in the past i have done too, however i couldnt be effed now, i just make me rum or vodka and off i go
i find a few hrs is all that is needed to get it going, even less really grund up etc, but i usually let it sit for a day or two, even longer sometimes...
i know some people may have issues with drinking and shroomin, and so it may not work for all, but it suits me..... alcohol relaxes the trip, always puts me in a good mood for the journey......and the alcohol extracts the good stuff real well...... and it really does sort the storage problem.......
