Clumps of sediment in Old Liquor

Hello everyone, I recently found this whisky cream liqueur at home, and I asked my dad how old it was, and he said something close to 25 years old.

As a new enthusiast of alcoholic beverages, I decided to open and try it. The taste itself is good and doesn’t seem rancid.

But I became concerned about the sediment that’s all over the liqueur. Of course, it’s old, some of its composition must have changed. But is it still safe to drink?

Other than that, I searched for this brand and couldn’t find it anywhere. Does anyone know it? (And could you tell me if this is the normal color of this cream?)
