A brewery is deciding when to release its new non-alcoholic craft beer infused with Davidson Plum. It has two options. 

Option 1: If it is bottled and released now, the beer will be worth $1.5 million. 

Option 2: If it is barrel-aged for a further year, it will be worth 20% more, though there will be additional costs of $500 000 in that year. 

If the interest rate is 7%, what is the difference (today) in the benefit the brewery will realize if it releases the beer after barrel-aging it for one year (option 2) or if it releases the beer now (option 1)?
