I fail to understand the incentive in bringing so much bottles of wine like 4-5 Bottles and carry it all the way through airports while the price of wines in Jakarta is not that particularly expensive.
You could get wine in Jakarta as low as IDR270k
We are selling Wine and Spirits with best price, and deliver to your door step. Providing more than 100 kinds of wine and spirits.

Unless of course, if it is a fine or vintage wines that are not widely available in Jakarta, your favourite wines for your own consumption and can not be gotten elsewhere. But I also doubt you could get this sort of wines in duty free Shop in the airport as this sort of wines will only attract specific customers and are not really popular for gifting.
For duty it is probably worthier to bring spirit and/or whiskies where the price different is quite signifiant ??
