Listed in the BJCP guidelines as the number one example of an American IPA and getting great reviews online, especially before the buy out!
If you google Alpine Duet Clone I’m sure you will find all the same info I did, it seems the brewery is very quiet about it recipes, there does seem to be just enough info to put together for Duet, and more than enough info for cloning Nelson, their rye IPA, for this beer there is even a video from the brewery!
So after several hours on the web I came up with the following for a 60L batch, mashed at 66degC, boiled for 90 min:

The brew day was un-eventful, all the number were hit, fermentation proceeded as expected, the beer was dry hopped and then crash cooled before kegging, after 2 days to carbonate it was tasting great.
What I would say about this beer is that it is balanced, the malt backbone supports the hops perfectly, and it’s all about the simcoe and Amarillo! It drink like a 5% beer it is truly neck-able to the point it’s dangerous!
Having never tasted a fresh version of this beer I have no idea if it’s cloned but it’s a very good balanced beer regardless. I was meant to enter it into the LSE comp but due to having to prioritise the time I have in the shed, bottling this never quite made it to the top of the list. Either way I would say it’s a 40 point beer which would have been in with a chance.
If i were to re brew i think i would increase the dry hopping to 200g per varity per addition giving 800g into 60L of beer, just to try and lift the aroma slightly.
Either way its a great IPA.
Cheers
