Aeration

Hello all,
Wrote to RC re aeration as he'd mentioned it a couple of times in his process threads. Thanks champ! I'm rather impressed with this and here's some prelim results.
Finally found a small volume air pump 50lt/hour. Pet supplies don't seem to generally stock these real small pumps and you may need to look around a bit to get one or order on line. $16 plus 1.25 for .5m silcon hose, .85c for 5mm pvc hose joiner(silcon to 6mm 1/4" copper) -Bunnos (neither in spirit only copper 6mm)
In a 19lt SS post mix keg had 4 gens of a malted rye spirit @ 65% abv totalling 17lt approx. Last gen was aired and timbered 1 weeks prior...like real new
Connected the pump on Sunday pm using a 1/4" copper tube L shaped foot to depth of keg, 4 x 1.5mm air bleed holes.
Left keg lid barely open and ran pump until Thursday pm = 4 days.
Rye as I've mentioned a few times does take a fair bit of time to mature/turn to a softer less sharp balanced spirit. Tried it Thursday pm and I'm very surprised how much it has mellowed. It's not ready by any means but its close after only change being the aeration. No significant abv drop noted in fact given temps could be = to zip.
RC mentioned he runs up to 2 weeks I felt that may be from initial timbering, cuts just completed and would be a tad long for a semi aged spirit?
Doc also mentioned several weeks but suspect much higher volumes and again new spirit here?
So intending to run up to another week with the rye and keep checking it periodically but at this early stage rather happy with ageing method.
Intend to try also:
5lt rum spirit... just after cuts
5lt Rye just after cuts
1 x 50lt Irish which is now 6 months in the keg.
Will advise as it progresses but well worth considering.
