Re:can i replace cooling water with air for the winter???
- thanks larry this is all great information.
i plan on using my 30 gallon air compressor which sits in my unheated
garage about 40 feet from the cellar. id use the compressed air in
place of water and from the unheated garage after compressing id
guesse the temp of it to be around 30-40 degreese F. my tap water from
the well is pretty stabel year round from the ground at 51-54 degreese F.
i do intend on trying the air and will let the group know how it does.
im not going to change anything on the still. i will simply replace
water with air so that if it dose not work then changing back will be
ive heard of the stone for areation. ive always filled my fermentor
with a hose and press my thumb onto the opening and spray hard the
water into the fermentor and get areation this way.
have you done it differently in the past and if so have you noticed
any differance between the stone and the previous method? which works
better? im always looking for ways to improve my methods.
