Sell 80k Liters of grapes. Can be done in 20-30mins. This is for example I did it on Haut Beyleron map but can be done on any map just place the multifruit station next to a grape selling point.
1. At the main menu go to downloadable content>most downloaded then click on and install the multifruit buying station. You can also download government subsidy sign as well if you don't want to worry about finances but it's not necessary.
2. Load up or start a new career on Haut Beyleron map on easy.
Make sure multifruit is checked off then enter the map.
3. Press menu button then
in, hover over field 8 then press
then press
and confirm to purchase field 8. It should be around 260-270k if you don't have that just sleep a few days if you have enough government subsidy signs up or get a loan.
4. Press
go down to others then construction>buildings>multifruit buying station. Place the station next to the selling point as close as you can in field 8.
5. You should already have a tractor but you need to purchase a tipper/trailers for grapes. It is under tools>grape technology. Once you have that purchased hook it up to your highest horsepower tractor and make you way to field 8.
6. Place you grape tipper under the buying station then press
to fill and select grapes. Drop it off at the selling point close buy. Rinse and repeat should take less than 30 mins overall.
This method can also be done with olives and sorghum which will take a bit longer and have different selling points and use different tippers as well.
