Finally (for now) I then ran the same GP/Pilsen LME recipe as last time; including the cup of mash into the fermenter.
For the strips, I collected to 10l lowwines per 20l wash (the ABV% was seriously low at this point).
With 7l feints and about 10l water, this made for a bigger spirit run.
On the spirit run after 'heatup', I turned the burner down so low it was running at about 1.5lph for the heads....needless to say, this became a longday in the shed.
In the end, I collected 'about' 6l hearts and, again, it was immediately like a good quality result esp sans the peatreek.

ops:
This time I changed up the oaking. I used 1 new charred stick, 2 reuse charred stick and 2 new MT sticks in with the hearts at 65% for about 2 weeks, then dropped the ABV% to around 62% for 2 weeks, the to 58% for 2 weeks.
This was recently 'barrelled' (too) but what I did notice was that there seemed to be a 'maple-like' foretaste to the oaked spirit that I had not noticed before.
Indeed I am keen to explore this further as it is a definite plus regarding flavour 'layering' (as all decent malt Scotchs have).
In summary here's what I have found:
Golden Promise malt is a worthwhile consideration.
The amount of LME can be varied, though its a good thing to include some, at least.
For peated Scotch lovers, malting Peat Smoked grain is the go, not using peatreek. A good bit of heavy charred oaking @65% is a worthwhile maturation addition too.
A very slow (ie around 2lph) final run using a significantly-diluted lowwines base with LOTS of feints is best regarding end product quality.
Pay particular attention to cutting the heads out of the drinking spirit....its a harshness that simply becomes counterproductive to enjoyment of the quaff.
Getting 'clever' with the oaking; namely use of a variety of 'cooked' oaksticks, perhaps varying the ABV% and employing the 'little quantity for a long time' oaking method works best.
This FSW recipe (and its variants like those above) has enormous potential to create a fine spirit, IMHO.
I like it lots....with a dash of water or a block of ice anyway.
