grams per gallon of "Trifecta mix"
« on: January 23, 2018, 03:16:18 PM »
So I finally got some BTB sold in the US through e-bay. I am ready to try out the Trifecta mix on a warm day, thank God, coming soon. My past usage of just SMB was set at 30ppm and have some good results with less than 10ppm Sulfites left in finished beer per test strips. I recently made a mash cap and wonder if I should reduce it more. I seen that last recommendation for Trifecta mix was .25g/gal, doing math for my next batch I get 1.9g of the mix for a 7.75 gal no-sparge mash. This breaks down to .87g SMB/.87g AA/.1g BTB. Does this look right, it seems to reduce the SMB slightly but then adds AA at .87g? In other words before I used .87g of SMB only and now I use that plus that amount of AA and .1g BTB. Sorry for the long post but I am not sure if I got this right and need to ask the forum members, thanks.

If you had good results with 30 ppm MBS, you could try an amount of SBT that will contain 20 (or 25) ppm MBS. That would be 0.17 (or 0.21) g/gal. The spreadsheet on lowoxygenbrewing.com contains a calculator for this kind of stuff.

Thanks for the reply, I have tried to use the spreadsheet but I don't have Excel only libre office. My main concern is adding more things to the mash then before. Are the 25-30ppm amounts  referring to total trifecta mix or just the SMB amounts in the mix ?  In other words, before I used .87g of SMB[sulfite] only and with the mix I use .87g SMB/.87g AA/ .1g BTB? This is what I am confused about, 1.84g of mix compared to .87g of just SMB used in batches before.

In the spreadsheet you put in the amount of SMB you want. Say 20 ppm. Since SMB is 45% of SBT, you will then add around 45 ppm of SBT, which will then translate into 0.17 g/gal. Which is why the imperial system was invented by a stoned sadist. ;)

I was able to open Excel on a trial basis and to input into the spreadsheet. Looks like I was looking at it right and there is a higher amount total going into the mash. At 30ppm for SMB in a 7.75 gal mash that amounts to around .87g each for SMB and AA, and .2g of BTB.  A total of 1.94 "Trifecta mix" going into the mash.  Thanks for the help Frank. By the way my Grandmother was born in Brussels, her family came to US during the first World War.    à votre santé , Mike

A distant member of my family emigrated to Canada after the war. He called himself Mike, but his real name was Marcel. From now on you are Marcel.

If you have all components separately (BtB, AA, and S/KMB) then you're best off picking your level of sulfites first (10ppm, 20ppm, 30ppm, whatever).  Once you know that amount, use the exact same amount of AA since they work in conjunction with each other.  Finally, use the widely-stated amount of BtB in your mash, and decide if you should use any in the boil.  The general feeling about where or not to use any in the boil is that if you have copper/iron somewhere in or after the boil, then use BtB in the boil as well at the widely-stated amount.  If you don't have copper/iron anywhere during/after the boil, then forego the BtB boil addition.

I would personally recommend a lower starting amount of sulfites than 30ppm if you're using any methods or processes that help mitigate oxygen ingress (15-25ppm).  If you're making no other changes to your system/process then 30ppm should be fine.

     My Grandmother and her brothers came to Canada first and then on to KC. I remember the story of Grandmother being bullied in school in the US because her last name sounded like  the Kaiser.

That's right her name was De Keyser. I'm part Irish and part Belgian so I have to like beer ;)
