As you can see there is 80g of Topaz there , 50g in late additions, so if there is flavour to be had, this beer will have it. Opening the vac sealed bag, the aroma was your typical pungent hop aroma that you get from most hop varieties. During the boil however, there was a noticable peppery aroma, like what you get with galaxy, only not as pronounced. Sitting here now sipping the beer above, I'm a little dissapointed. Topaz is no galaxy in the "sticking out like dogs balls individuality stakes" It has the same flavours as a number of high alpha hops, pacific gem, warrior, southern cross and to a lesser extent, magnum. What is the flavour? well, I would put as resiny, spiced fruitcake, this is backed up by The Scientist who simply said "fruity". It would probably make a good bittering hop if the fruitiness does not hang around too long in the boil. Has anyone else usedit? what are your thoughts?

cheers

The only Topaz sample I have experienced is a zwickle out of a fermenter, where Chappo had used Topaz for an Aussie lager. It reminded me of a cross between Galaxy and POR, but without a big, upfront aroma note that Galaxy is known for. It had a citrusy, almost pine type flavour. It seemed to be a little bit disappointing as the flavours it seemed to contribute were just variations on existing themes rather than being something unique. The only disclaimer I'll put on this is that this beer ended up being infected, so I'll leave some more detailed analysis to others...

Bump.
Clean Brewer, How did this one turn out? I've got some Topaz I want to give a run.

 

[Pollux]

Got a 90gram shrink of Topaz as part of my order today, will have to work out a recipe for it.

Hey rosswill,

Turned out ok, I would probably use the Topaz as later addition hops though in the same beer again and probably wouldnt use it as a single hop beer, found it too fruity, citrusy and maybe the same as some other comments as Grapefruit....

Maybe its the same as the description for Chinook "Use caution when adding to early boil, as grapefruit can dominate." Maybe try it for a flavour/aroma hop and try a neutral bittering hop or combine it with something else???????? :unsure:

Ive only used it once and still have 50+grams left, so will try something similar in Grain but adjust the hops a little, all trial and error hey.... Wouldnt say it was terrible though....

:icon_cheers: CB

Bottled a topaz ale recently, never used it before.

It is -
71.5% Ale malt
15.2% Munich II
5.1% Med Crystal
8.2% Wheat Malt

10g Topaz at 30,20,10 min & flame out to 32 IBu inc 15g dry hop.

With a 2112 Cal Lager yeast.

Got a one chilling in the fridge at the moment (all be it very early) that was just short of a full bottle (rather like myself I guess :unsure: ) Which I kept as a tester.

Early impressions of it though were a strong resiny fruity character, but I'll reserve my opinion on it until later.

Cheers,
BB

Having just tried it - definite grapefruit flavours going on there, its dominant but not in any unpleasant way, a nice aroma as well.

Overall, I'm pleasantly surprised, IMHO it would combine well with many other fruity citrusy hop varieties.

Cheers,
BB

Necro thread..

I had a good whiff of these over the weekend and I got a little aroused.. Pine and fruit (as Noted above and in the HPA data sheet)

I think that one of my next cubes will have be a topaz cube, maybe mixed with a little Mosaic, Citra or Calypso

[Jaded and Bitter]

Just cracked the first bottle of a 28Lt 1.060 40 IBU American Brown Ale tonight. I did an all Topaz Strong Ale last Autumn and didnt like the bittering. Hopping as folllows:
Bittering - German NB
20 min 25g Chinook + 25g Amarillo
5 min 25g Chinook + 25g Amarillo
DH 50g Topaz Flowers

Aroma very pleasant and well balanced, the Topaz rounded out the other hops giving a full caliedescope of citrus aromas, piney, citrus, passionfruit, black currant?, spicey, herby and earthy.

Ive used the Chinook/Amarillo combo before and found it a little one dimensional (ok maybe 2D), The Topaz did really round out the aroma.

Deffo an American Ale Flame Out or Dry Hop.
