(ABC) - A Western Australian grape grower has been able to get a second crop of fruit, after a hail storm wiped out most of his vineyard.

"The hail itself is what I class as severe. All the green foliage was fully defoliated," said Rod Hallett of Alkoomi Wines in Frankland River, 320 kilometres south-east of Perth.

After some quick thinking and heavy pruning Mr Hallett said he was thrilled to see some crop return, after 90 per cent of his vineyard was essentially wiped out.

"It's a gut feeling and knowing your plants. You do what you think is right at the time. It just worked out for the best. It was the best thing we did.

"Basically there were no buds left on the vine. We took it back to the original pruning wood. From there, we basically started again and we've had a pretty good result.

"Quality and flavour wise, everything seems to be tracking well, we're just a little bit behind everybody else for this time of year.

"But that's probably a good thing in a way, we've missed the heat so we've had no shrivel or sunburn.

"Our fruit is in really good nick."

Alkoomi's 2015 vintage is taking a little longer than usual; all the white grapes have been picked and they are still a few weeks away from the reds.

Mr Hallett said he was expecting yields of between 35 to 40 per cent from the second crop of fruit.

"Originally I was hoping for about 50 per c
