and the results are in on the hot and cold steeped McClelland M27 3 Cherry.
Cold steeped M27 24 days room temp PGA
Hot steeped M27 24 hrs 130F PGA in crockpot on warm setting
Both extracts were reduced to aprox. 20% of original volume after initial filtering in crockpot lid off on high 150F
after reduction, they were filtered again thru pleated coffie filters
both reductions were mixed with equal volumes of VG to stabilize, concentrate is transparent but dark.
Arouma is heavy with cherry in both samples, the cold steep has a "brighter" note to it than the warmed extract, but the warmed ext. has a more earthy note to the tobacco.
In general, the warm extract has a deeper body to it, the cold a lighter but still intense smell ummm lets call it an octave higher
took both concentrates and made a set of 20/80 mix ( C/VG) to test for vaping didnt add nic, want to taste the mixes.
The warm version is smooth, a bit earthy/lightly grassy ( chlorophyl??), the cherry is a mild flavor but quite prominant, not a tart cherry flavor, reminds me of fresh ripe cherries that have been "saw-tayed" ( my french is terrible

) the tobacco flavor is smooth and has a toasted nut hint to it...
The cold version is... very nice

cherry pops in this one, very noticable cherry up front. The cherry is "lively", the grassy aspect is missing in this one, tobacco flavor is smooth and still has a nutty aspect to it but seems to be "less roasted/toasted" flavored.
Im almost considering on actually smoking a bit of the tobacco to compare it to the extracts....
Seems the cold extract brings out the bright side of the flavors and warm/hot has a tendancy to bring out the "heavy side" of the tobacco.
I starting to wonder if the heating during reduction changes flavors in the extract.... next experiment, reduction without heat above room temp. Maybe a cookie sheet and a muffin fan, broad expanse evaporation method.... its a thought
Im really liking this cold extract sample/mix...
