Another pumpkin spice question

Quick question. I completely forgot to add the pumpkin pie spice to the last 5 minute boil of a brown ale I'm doing for Halloween (after years of using real pumpkin I've found it to be pointless and a pain). Figured no big deal and will do a vodka tincture at kegging. How much vodka? Never made a tincture before. Do I just mix spice in vodka with spoon and just rack on top in keg? Plan on using about 4 oz, I know it's a lot but 2 0z never comes through enough. Thanks!

 

You normally use two ounces of pumpkin pie spice in your beers and it doesn't come through enough? I use at most 2 TEASPOONS for a 5 gallon batch and find that to be more then enough. I would make the tincture ahead of time, like a few days and store it in the fridge. That should allow the vodka to take on the flavor and the spices to dissolve. Shake it up now and again if needed. Your really only need enough vodka to dissolve the spices if you already know the amount of spice you are going to use

 

I meant 2 teaspoons lol, sorry

 

4 tablespoons is what I meant. I've used 2 at flameout and I didn't think it came through as much as I wanted. Hoping the tincture is much more prominent. Maybe I should start with 3
