Hop pellets - use by date?

Postby crispylettuce » Fri Jan 27, 2017 08:22

For a variety of reasons I didn't brew as much as planned last year and as a result I have hop pellets that have been stored in air tight bags in my freezer - some of which have been there for 10/11 months now.

Will they still be OK? Or did I bin them and buy some fresher ones?

I reckon worst case scenario is you've lost a little bit of aroma and you use them for bittering.

Personally, I'd just use them - I've used hops older than that with no problem at all.

2016: 330L brewed (72 gallons, over 8 firkins)
2017: 105L brewed (need to update this figure)
Drinking: Landlord clone
Conditioning: ciders from 2016, hedgerow barrolo, 1914 Courage RIS (10%).

I'd expect them to be okay if they were reasonably fresh when you got them, especially if they smell normal when opening. Hops don't go off easily, and keeping them cold and sealed is also a good thing.

It is often held that their alpha acids reduce (or transform) over time, and that this results in reduced bittering, though keeping them cold slows the process. However, not everyone agrees on this effect (or on the rate of it), and certainly when I've tried to compensate in the past, using calculators or established formulae, their suggested increase in quantities has been too much. So, with foil vac-packed and refrigerated hops I make little/no compensation these days, within a few years of their harvest date.

If they smell good, they're still good for aroma. If they don't, use them for bittering and add 10% extra

Every hop variety has a storage quality prescription. Some can be stored 3 years other only one year. In general aromatic hops need to be used earlier after harvesting. Bittering and dual hops could be used latest within 4 years after harvest. Loosing alpha acids is also in the prescription of the hop variety. So adding some more could do no harm. Try FWH to utilise more alpha acids in your brew too.
