Farming grapes and turning them into wine can be very profitable as the wines (mainly Wine of Zamorak
and Wine of Saradomin
) are used for popular high-level potions. To maximise profit, you should have:
Without these items, grape farming is much less profitable.
Begin your run at Seers' Village with 10 oak planks, 8 grapevine seeds, 2 supercompost and 2 Miraculous treatments. Pick the grapes from the patch, using the leprechaun to note all grapes. When the patch is empty, apply supercompost first, then build a frame with 5 oak planks, and finally plant the seeds.
Use Watchtower Teleport next, exit the building and go directly east and use the underwall tunnel agility shortcut to cross into Yanille. Repeat the process for harvesting and planting grapes here. Run to the bank and take out 10 more oak planks, 8 more seeds, 2 more supercompost and 2 Miraculous treatments.
The next patch should be the Lumbridge patch. Travel here by using the Combat bracelet teleport to the Champion's Guild and running south-east, jump over the fence. Harvest the Grapevines. Before leaving, store your magic secateurs with the tool leprechaun, or place them on your tool belt.
Next you should teleport to Port Sarim (a captain's log is the best option) and take the boat to Entrana. The patch is directly west of where the boat will take you. In case you have any equipment that is not allowed on the boat (like the Farming cape) use the deposit box by the boat.
Once there, withdraw your secateurs from the leprechaun tool storage, and then harvest and plant your grapes.
Finally, teleport to any bank and create wine. Grapes must be used on the jugs of water, vice versa does not seem to work. Also, note that wine can ferment in the bank, so you do not need to wait for it to ferment before starting a new inventory.
