If you have your alcohol packed in your suitcase and checked-in, the alcohol will not be removed. There is however, lots of uncertainty and differing opinions and/or experiences whether or not alcohol carried as duty free items will be seized at Doha Airport whilst on transit.
Your duty free allowance is determined by your final destination - i.e. where you're travelling to. Say if you're disembarking at Seychelles, you will be permitted to bring in 2 litres of spirits and 2 litres of wine.
Hope this info helps ...
