NEW YORK — Keurig Green Mountain, which made its name as a maker of single-cup coffee machines, is laying off more than 100 workers after its Keurig Kold home soda machine system fizzled out after less than a year.

The company said Tuesday it’s discontinuing the first generation of Kold and offering customers refunds for the full purchase price. The home soda-making machine debuted last fall to questions about its affordability for the average consumer.

Keurig said 130 employees will be affected, 108 of them in Vermont.
