Hash is pressed and heated, essentially converting most to mycrene or something I forget now. Most hash has similar notes regardless of strain.
Royal hash from Morocco in times long gone was said to be the best, reserved for royals as the tale goes. Farmers would cut the plant and leave it in a barn or corner somewhere for six months to a year to get the full cure and smoothness then make hash and store that for the same time six months to a year so that it can again cure. Longer than this was said to see the strength get weaker.
Everything is a personal journey I'd take dry sift over hash anyday but well made hash with a good cure, now that's top draw all day long.
Doesn't have to be complicated just roll a hot water filled glass bottle or jar over a cling film packet of them and piece of paper between the two and watch the magic happen slowly as that light brown parcel slowly turns dark and melts into a solid block.
Shit plants make shit hash, if the bud smokes bad often the hash won't be very appealing I've found. You can weaken and built the hash out by mixing some ground leaves into the dry sift then making hash, your second third and forth runs probably have more plant material in and makes it not quite as potent, sometimes the hash I've made was a little too strong and found some ground leaf made a better product sometimes.
Really enjoyable to make, if you got a decent amount of trim and bud I'd suggest using a few methods on it to see where you feel your at and liking.
