Vine cuttings are of specific types. Currently each University that has viticulture unlocked provides a different strain.
* Distraction, Karnak * Balance, Seven Lakes * Appreciation, Lower Egypt * Contemplation, Desert of Shades (also Mind of the Ancients contest prize) * Wisdom, Kush * Amusement, Cradle of the Suns * Frivolity, Khartoum
Now, there are lots of different hybrid vines (produced through crossbreeding/mutagenics), many of which produce superior results than the base vines.
You can also acquire vine cuttings, once every 2 hours, from a vineyard that has that type of grapes growing on it.
There was a Cutting named: Old Tawny gave out from the UWorship, but cannot used at vineyard
Every hour, you are able to tend the grapes on a vineyard. There are several different states the grapes on a vineyard can be in, and several different ways of tending them.
Vineyard state:
* The vines are sagging a bit * Leaves are wilting * A musty smell can be detected * Stems look especially fat * Leaves rustle in the breeze * The grapes are starting to shrivel * Leaves shimmer with moisture
Tending methods:
* Aerate the Soil * Mist the Grapes * Pinch off Weakest Stems * Shade the Leaves * Spread out the Vines * Tie the vines to the Trellis * Trim the lower leaves
Each combination of Grape Type, Vineyard state, and Tending Method has a different effect upon the statistics of the grapes in the vineyard.
