mature vines can have roots 8ft deep and around the surface of the vine. if you can dig up and reserve a good amount of roots they may survive a transplant.
planting vines east to west is fine. The grapes will achieve highest sun exposure, Caution on the wine break as the shade does not reach the vines. you will receive lower growth and harvest because of the shade.
I decided to approach the corking in another way. I bought screw top bottles using the Stirling finish. found the screw tops on net. as you can see from the video Steve modified his corker to pneumatic. suggest contacting him for any advice.
it is residue from the fermentation. you should ferment in a open bucket then cover with a towel. this would give better access to the must. if you have a bucket move the fermentation to it now.
a air lock is required to release gas as the wine ages. also any sediment would cling to the sides of the carboy instead of the bottom. follow tradition it has its reasons. keep carboy up and add water to a air lock
normally #8 or#9 corks are used for wine bottling the #9 are slightly larger. I used these for long term storage on wines. if the bottle is for screw caps the opening is smaller and a #8 is recommended it still may cause and indentation.
I have had good luck adding 3/4 cup sugar for 23 liters of wine. need to stir about two minutes or more to assure sugar is dissolved. bottle to champagne bottle with wired plastic cap.
used a refractometer thru fermentation for over 20 years with correction table works great. there is an argument that at low values near finish it may be inaccurate even though corrected. just use a hydrometer at this point if necessary.
