Below is an instruction that describes a task. Write a response that appropriately completes the request in English. Please answer in English.

### Instruction:
Borris liquor store uses 90 kilograms of grapes every 6 months. He is thinking of increasing his production by twenty percent. How many grapes does he need in a year after increasing his production?

### Response:
Borris uses 90 x 2 = <<90*2=180>>180 kilograms of grapes per year.
He will use 180 x 0.20= 36 kilograms more grapes per year when he increases his production.
Therefore, he needs 180 + 36 = <<180+36=216>>216 kilograms of grapes in a year.
#### 216
