Temperature and yeast

I made apa using cascade hops 50g, added 25g at 5min and 25g at flameout using s-05, but there is not much cascade aroma or flavour in the finished beer. I've used this yeast other times and normally get great hop flavour in the beer, but this time the beer was fermented at a lower temp about 17-18c maybe lower, compared to 20-22c when I have had lots of hop flavour and aroma. So can brewing at lower temps change one of the main qualities of this yeast, and not highlight the hop flavours in the beer.

you sure it was hop aroma and not esters you were noticing? also, what temp do you serve the beer at?
cheers

More likely the temp it is served at that would have the effect on the hop aroma not the temp it is fermented at.

I have made this style of beer plenty of times, but this beer is really bland for the style, you can only taste the bittering hops. It was served at about 5-7 deg. Other apa that brewed at 20-22c have hade great hop flavour. This beer is like i didn't add any cascade.

Funny thing is the last Coopers International APA I did was the same. Except that I used POR. It came out bitter and tasteless! I used 12 grams at 15 min and 12 grams dry hopped when racking. Wouldn't even know I had hopped it at all!

Switch the flame out addition to dry hopping. Flameout additions, especially small ones like that, are going to get scrubbed out during fermentation - Dry hopping is the way to go. also make sure you buy the freshest hops & store any unused ones airtight - Cascade in particular don't keep well at all.

I would like to point out the hops I used were the teabag kind and not from Ross

I think you answered your own question as to why you haven't got any aroma! The tea bag style hops were probably not the freshest and could have sat in the shop for a year and stored incorrectly. If you open a pack of hops and there is very little aroma you have buckley's chance of adding any aroma to your beer. Do yourself a favour and buy some hops from Ross, you'll be amazed. SERIOUSLY!

I agree.
Every HBS i have been to store their teabag hops at room temp, on a rack in the store. Some dont evne have air con, so the Hops can get up to 35-40*C.
But they always store the larger bags of hops in the freezer.
Not to mention, they are much better value...

I couldn't agree more. The results from the hops I've bought from Ross have been fantastic, a genuine hop flavour and aroma. The teabags I used previously seemed to have achieved very little, if anything.

G'day B.E,
I'm not sure what you're driving at here? Are you thinking that the yeast stripped the aroma and hop flavour from the final result? SAF ALE S-05 American Ale / Chico Strain yeast (aka Wyeast 1056) is a clean ale yeast that is used in the production of Sierra Nevada pale ale - and I use it all the time as an excellent all round APA yeast - it's never blunted the crisp bitterness, flavour and aroma profiles I aim for with fresh hops in my APA's.
Did you use fresh hops or the tea bag hop crap too?
Cheers,
TL

Hi TL
I used the hop pellets and they where stored in the freezer when I bought them.
I use this yeast all the time for apa as well and have never had this happen, but on this occasion it's like the cascade has been stripped from the beer. I have been thinking about this, and something else I did different was that I boiled the hops in greater malt to water ratio then I usually would, because I used a fresh wort kit this time. Maybe that had an effect on the hop utilization percent.

What's the best way to store hop pellets? I've got mine in a jar at the moment sealed as room temp. Better off in the fridge / freezer?

I keep mine in the freezer in an airtight container or the bag they came in.

Airtight container in the freezer to minimise spoiling - hops spoil quickly at room temps.

Firstly, a disclaimer - I've never used one of these fresh wort kits - but they sound like fun and a nice way to shorten the brew session's duration! I agree that you've probably used less hops than you would have liked and the fresh wort kit dropped your utilisation...I guess it's something you'll mark down to experience...I keep notes for every recipe and brew session since my first batch in 1995 - for this very reason - making a mistake is fine; repeating the mistake is unforgiveable!!
