Hop IBU Injectors?

[golfgod04]

Has anyone used Hop IBU Injectors? A few places are selling specific hop variety IBU Injectors. They all say to use at late boil / flameout / whirlpool.

They are strictly for IBU's and only useful to "inject" during a full-rolling boil of the very start of the wort, such as 90 minutes.

I found a couple of these in my freezer. Likely 2 years old. What is the shelf life of them?

that is the novarietal hopshot instructions.

Here's the instructions for CAscade IBU injector "Current AA - 50%
Variety specific hop extract.
Can be used late in the boil or whirlpool to get variety specific flavors and aromas."

According to comments I read on the bittering hopshot I was looking at on morebeer it's indefinite if stored correctly.

As fare as shelf life, it was the intention of concentrating it for longer storage then just a season. Ive only used them for bittering, farm house has several single hop versions cascade citra chinook and eldorado. I was wanting to make a ipa with the chinook and citra. I figued id have to dry hop tho i cant think how to use the hop shots for that. I was think

11# 2row
8oz honeymalt
8oz oats
1# flaked wheat 150* 60min mash
60 min 50 ibu shot
15min irish moss, kdap
0min 5ml of both cotra and chinook
Chill to 170 10ml both citra chinook for 30min
Esb yeast
Day 3 1oz citra 1oz chinook dry hop
After ferm 1oz citra 1oz chinook

I dont know if i would ne adding enough hop shot for a hop bomb but if any one knows how ml convert into oz of hops that would be great.
