Vietnam, the world’s largest grower of robusta beans, will probably see a drop in its coffee output in the 2014-15 crop, which starts from October.

The decline is attributed to the previous bumper crop.

The harvest may shrink by 4 percent to 1.64 million tonnes from 1.71 million tonnes a year earlier, according to the median of 12 trader and analyst estimates compiled by Bloomberg.

While the Bloomberg survey showed a contraction in output next year, the Foreign Agricultural Service of the US Department of Agriculture expects an increase. It says Vietnam will produce 29.2 million bags (1.75 million tonnes) compared with 29 million bags a year earlier, according to a report on May 23.

Earlier, the Vietnam Coffee and Cacao Association (Vicofa) forecast a fall in Vietnam’s coffee output in the 2014-15 crop due to the prolonged unfavourable weather conditions so far this year.
