Dwarven stout

The Dwarven stout is a free-to-play Old School RuneScape item — “A pint of thick dark beer.”. Its Grand Exchange buy limit is 2,000 per 4 hours. Right now it buys at 100 gp and sells at 128 gp — a net margin of 26 gp (26.0% ROI) after the 2% Grand Exchange tax of 2 gp. High alchemy yields 1 gp.

To flip it, place a buy offer near 100 gp and a sell offer near 128 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
