Greg Johnson  one of Anxo's cider-makers   attaches an air of romance to cider.

Wine has long had its connoisseurs. With the rise of the craft beer movement  drinkers have learned to appreciate the nuances of that brewed beverage  too. But cider  in many drinkers' imagination  remains an unrefined  blandly sweet drink  says  Johnson . The reality is far different   he  says.
"There's a whole expansive world  just as expansive as beer  just as expansive as wine. I just keep working to show people that "  Johnson  says.

question:
Germany's Audi has abandoned plans to sell its Italian motorcycle brand Ducati  its chief executive Rupert Stadler said  in a sign of confidence that the carmaker expects to be able to carry the costs of its transformation.
Steps to reduce costs by 10 billion euros ($11.8 billion)  cut red tape and deepen ties with fellow Volkswagen-owned brand Porsche are "gradually increasing our financial and organizational leeway for the strategic realignment " chief executive  Rupert Stadler  told reporters.
There is  therefore  no economic need to sell Ducati   Stadler  said. Volkswagen asked banks to evaluate options for Ducati and transmissions maker Renk earlier this year as seeks to become more nimble in its shift towards electric and self-driving cars following its diesel emissions cheating scandal.
"I can assure you that Ducati belongs to the Audi family " said  Stadler . "Ducati is the perfect implementation of our premium philosophy in the world of motorbikes."
While pushing the costly shift to zero-emissions and autonomous technologies  holding on to the profitable Ducati division and the lucrative Lamborghini brand has become more important   Stadler  said.
"Looking after a premium bouquet is as difficult as the work of a gardener "  Stadler  said. "Therefore I am pleased with every new flower  with every promising new branch " he added  predicting Lamborghini's sales would double on the back of its new sport-utility vehicle.
Separately   Stadler  said Audi will spend nearly half a billion euros over the next eight years on training staff for the digital age  with steps to develop as well as hire experts such as automotive app-designers and car robotics specialists.

question:
Bitcoin's price has fully recovered from  its  recent slump after  JPMorgan CEO Jamie Dimon  called it a fraud and Chinese regulators cracked down on exchanges.
The cryptocurrency had a drawdown of up to 14% in the 10 days after September 12  when  Dimon  compared it to the tulip bubble of the 1600s and vowed to fire traders who used it.
By Thursday  bitcoin had all of the losses. It was up nearly 2% from the lows on the day  Dimon  spoke  at $4157.31 per coin at 10:28 a.m. ET.
The move illustrates bitcoin's wild volatility; it's gained 331% this year  unheard of for any major currency and most financial assets. It also shows why many Wall Street professionals like  Dimon  don't see it as a legitimate store of value but as a speculative instrument.
answer:

Jamie Dimon
