(The drinks business) - Screaming Eagle’s 2013 vintage soared in May, rising nearly 20%, as the Liv-ex 100 index also posted a positive gain.

After a choppy first quarter of the year, the benchmark index (which charts the 100 most commonly traded labels in the secondary market) has now posted gains for two consecutive months, with a small 0.3% rise in April and now a more substantial 0.5% gain last month.

The month’s most successful label was the 100-point (Robert Parker) 2013 Screaming Eagle which gained 18.5% to a new mid-price of £23,700 per dozen. Liv-ex reported that there has been a fair amount of movement in the Screaming Eagle portfolio recently, with the 2015 also seeing “significant price increases”.
