Grapes

Overview

Grapes are trellis-grown fruit crops in Starsand Island that come in two variants: Green Grape and Red Grape. Together they provide year-round grape coverage, since Green Grapes grow in Spring and Summer while Red Grapes grow in Autumn and Winter. Both variants share the same growth time, seed cost, sell price, and yield, differing only in their seasonal availability and the buff granted by their juice.

As multi-harvest crops, grapes produce fruit multiple times from a single planting before the vine dies. This means farmers do not need to replant between harvests, saving both seeds and stamina. A single grape plant yields 2 grapes per harvest across 3 total harvests, producing 6 grapes from one seed over the vine's lifetime.

Grape Seeds unlock at the Junior Farmer tier of the Farming profession and are sold at the Happiness Seed Shop for 150 Coins each. Grapes are essential for the Junior Farmer trial, which requires growing and harvesting a total of 30 grapes and then processing them into juice using a Juicer. Beyond the trial, grapes are prized for their juice recipes, which grant highly valuable exploration buffs.

Grape Variants

Starsand Island has exactly two grape variants. There is no Purple Grape or any other color in the game. The two variants share identical stats and mechanics; the only differences are their growing seasons and their in-game descriptions.

Because Green Grapes cover Spring and Summer while Red Grapes cover Autumn and Winter, a farmer who plants both variants can maintain a continuous grape supply throughout all four seasons. This is particularly useful for players who rely on grape juice buffs for mining and logging.

Growing Grapes

Trellis Requirement

Unlike most crops that grow on regular farmland or in paddy fields, grapes are vine crops that require a Trellis to grow. A Trellis is a vertical support structure that the grape vines climb as they mature. You must place a Trellis on your farm before you can plant grape seeds. Each Trellis supports one grape plant.

One advantage of trellis crops is that the soil under them does not need to be tilled. This saves stamina compared to ground crops that require hoeing before planting. Simply place the Trellis, plant the seed, and water the plant daily.

Multi-Harvest Cycle

Grapes are multi-harvest crops. After planting, the vine takes 3 days to produce its first batch of fruit. Once you pick the grapes, the vine regrows and produces another harvest after 3 more days. This cycle repeats for a total of 3 harvests before the vine dies and the Trellis becomes available for replanting.

• Day 1 to 3: Initial growth period after planting.

• First Harvest (Day 3): Pick 2 grapes. The vine begins regrowing.

• Second Harvest (Day 6): Pick 2 more grapes after the vine regrows.

• Third Harvest (Day 9): Pick the final 2 grapes. The vine withers and the Trellis is freed for a new seed.

Over the full 9-day cycle, a single grape seed produces 6 grapes worth 95 Coins each, totaling 570 Coins in revenue. After subtracting the 150-Coin seed cost, the net profit is 420 Coins per plant, or roughly 46.7 Coins per day.

Watering and Fertilizer

Grape vines require daily watering. Setting up sprinklers near your trellis rows saves considerable stamina, especially if you maintain a large grape operation. Fertilizer can be applied to speed up the growth and regrowth cycles, allowing you to squeeze more harvests into a single season.

Recipes

Grapes can be processed at several crafting stations to create juices, jams, and cooked dishes. The juice recipes are especially popular because of their powerful exploration buffs.

Grape Juice (Juicer)

The Juicer turns raw grapes into juice. Both variants use the same recipe format but produce different products with different buff effects.

Green Grape Juice grants the Bonus Ore buff, which increases the amount of ore you receive when mining. This is extremely useful when farming minerals in areas like the Moonlit Forest.

Red Grape Juice grants the Bonus Timber buff, which increases wood yield when chopping trees. This makes it the go-to drink for logging runs and stockpiling lumber.

Both juice buffs can stack up to 5 times, so drinking multiple portions before heading out greatly multiplies your resource yield. Grape juice is widely considered one of the easiest and most efficient buff foods to produce in bulk.

Grape Jam (Jam Maker)

The Jam Maker converts grapes into jam using sugar as a secondary ingredient.

Grape jam is a processed food item that can be sold for a higher price than raw grapes. It also makes a good gift for several island residents.

Other Grape Recipes

Grapes can also be broken down in the Separator to produce 8 Fruit Pulp per grape, which is useful if you need Fruit Pulp for other recipes or crafting.

Seed Recovery

If you run out of seeds, you can convert grapes back into seeds using the Grinder. Placing 3 grapes into the Grinder produces one seed packet of the matching variety. This is a handy way to sustain your grape supply without returning to the shop, though buying seeds directly is more grape-efficient if you have the coins.

Junior Farmer Trial

Grapes play a central role in the Junior Farmer trial. One of the trial objectives requires you to harvest a total of 30 grapes. You can use either Green Grapes or Red Grapes (or a mix of both) to fulfill this requirement. The trial also requires you to process grapes into juice using the Juicer.

To complete the trial efficiently, consider planting at least 15 grape seeds at once. With each plant yielding 2 grapes per harvest, 15 plants will produce 30 grapes in a single harvest round. You can then immediately juice some of those grapes to satisfy the juice-making portion of the trial.

Buy your seeds from Graminova at the Happiness Seed Shop. The shop is open from 10:00 AM to 9:00 PM daily and is located in Starsand Town near Ethereal Styles.

Everlasting Seeds

Everlasting Seeds are special seed variants that produce crops which regrow indefinitely after every harvest. An Everlasting Green Grape Seed or Everlasting Red Grape Seed means the vine never withers, providing an unlimited number of harvests from a single planting.

There are three ways to obtain Everlasting Seeds:

• Drop from completing Islandpedia entries.

• Found in lucky chests while tilling soil.

• Crafted through the Eternal Blessings skill, unlocked at the Senior Farmer rank.

If you dig up an everlasting crop, the Everlasting Seed is returned to your inventory so it is never lost. For grape farming specifically, everlasting seeds are extremely powerful because they turn a trellis into a permanent grape source. Combined with sprinklers, an everlasting grape vine requires almost no daily maintenance beyond harvesting.

Eating Mirthshroom Soup before harvesting is said to boost your chances of converting a regular harvest into an everlasting variant, and the effect stacks, so consuming multiple portions before a big harvest session can improve your odds.

Gifting

Both Green Grapes and Red Grapes share the same gifting preferences, making them interchangeable as gifts regardless of season.

With eight characters loving grapes, they are one of the more universally appreciated fruit gifts on the island. Since grapes are available year-round between the two variants, they make a reliable staple gift to keep in your inventory. Graminova herself loves grapes, which is fitting given that she is the one who sells the seeds.

Profitability

Grapes offer a moderate income stream. Their real value lies less in raw crop sales and more in the powerful buffs provided by grape juice. Still, for farmers interested in the numbers:

Compared to higher-tier crops, grapes are not the most lucrative option for pure coin farming. However, their value increases significantly when factoring in juice production. Grape juice restores 98 Energy and provides exploration buffs that can lead to higher returns from mining and logging trips.

Tips

• Plant both Green Grape and Red Grape seeds to maintain year-round grape production. Green covers Spring and Summer; Red covers Autumn and Winter.

• Place trellises in a row next to a sprinkler line so all your grape vines stay watered automatically.

• Stockpile grape juice before major exploration or mining trips. The Bonus Ore and Bonus Timber buffs stack up to 5 times and dramatically increase resource yields.

• For the Junior Farmer trial, plant at least 15 seeds to get 30 grapes in one harvest round, saving time.

• Use the Grinder to convert 3 spare grapes into 1 seed if you run out between shop visits.

• Grapes make excellent gifts since eight characters love them. Keep a few in your bag during daily rounds.

• If you obtain Everlasting Grape Seeds, prioritize placing them on trellises with sprinkler coverage for truly hands-off grape production.

• Avoid giving grapes to Cat or Ferret. Both characters dislike them.
