"To produce more coffee, the civets were forced to eat large amounts of coffee beans."
I saw this sentence on the Ivy magazine (published in Taiwan). We all know that we should use amount with uncountable nouns, but here it goes with coffee beans (a plural countable noun). Is it correct? How about I change it into "large numbers of coffee beans"? I have to say the use of "numbers" here sounds odder, though. Thank you.
