Australian wine maker Tyrrell's is launching a range of wines named after a vintage that was unintentionally allowed to ripen for longer than usual.

Some weeks after the harvest for the 1993 vintage, a very ripe unpicked block of Semillon was discovered at its vineyard, which led to different flavours.

The Lost Block range follows this principle, using very ripe grapes to produce fruit-laden, fresh and easy-to-drink wines.

The range, which will be on display at this year's London International Wine & Spirits Show, includes a Semillon, unwooden Chardonnay, Merlot and Cabernet Sauvignon, all priced at £7.99 each.
