why are stems kept on or removed from grape bunched for pressing
in a press they act as channels for must to flow quickly (important wine you do not wish for pigment)
stems absorb sugar and acid
Green stems can impart bitterness and astringency, while brown stems can impact spice
what often causes a fermentation to get “stuck”
grey rot
chemical residue
hi temperature - kills yeast
cool temperature - stops and then yeast racked off
what is sterile filtration
removing small bacteria (centrifuging, filtering or fining) but can remove desirable aroma and flavours
three methods to extract colour and tannins
Punch down - Pigeage
Remontage - Pump over
Delestage - rack and return - the more alcohol the more extract (acts as a solvent)
