Tasmac — Adulterated Signature Whisky

Address:

Villivakkam

Greetings
I recently purchased 2 bottles of Signature Whisky 1 litre bottles from Tasmac Elite Anna Nagar 2nd Avenue. I opened up one bottle and it tasted very bland...I have been buying this brand regularly from the same shop but only this time it was different.
I am attaching a photo of the batch and details. I still have the 2nd bottle unopened just in case it needs to be tested.
Hope to hear from someone soon.
Thanks
