first biab advice please

Post by whitstella » Mon Nov 11, 2013 10:26 pm

hi fokes

just moved into our new house so thinks its time for a brew day. so new home new brewing method after doing kits and extract its now biab and my first go im trying a belhaven 80 ive been looking for belhaven best recipe but not found anything. ( a mate had it up scotland and loved it so i have found the 70 80 and 90 recpies) so belhaven 80 out of the bible wheeler book it is.

can i just ask a few question about biab and im looking for very simple answers to my questions.

them going through the process step by step can you correct me if im going wrong.
i want about 45 litre of wart for 2 cornies.

1 fill biab pot with 60 litres of water (or can i mash with less)
2 bring up the temp to about 70 (so once grain is added should drop to 66 - 68)
3 add the measured grains to the pot in a bag for 90 mins (how does over night mash work regarding temperature drop?)
4 do i need to raise the temperature before removing the grain if so what temp should i remove the grain???
5 do i rinse the grain with hot water if so what temp of water????
the boiling process im ok with after doing extract, should i add wheat for a better head and how much????

what is best irish moss or protfloc etc????

best yeast for the belhaven or should i try 2 different ones and see the differance

cheers for your help, just need it nice and simple for my first 1.

I do a maxi biab in a small pot, too small for all the water. But:

1. Full BIAB has all the water in with the grain in one go.
2. I aim for 75C to get a temp of 67/69ish. It drops 6/7 degrees.
3. I put the bag into the pot and then add the grains slowly while stirring. That may not be appropriate for larger scale BIAB, take too long and lose temperature.
4. Raising the temp at the end is good, called a mash out, people do up to 75-80C
5. I rinse the grain, but full BIAB (all your water in at the start) does not require that. The high volume does the job of getting all the sugars out, I believe.
6. I use Irish moss, not used anything else yet, it works.
7. If you mean business get a White Labs WLP028 Edinburgh Ale liquid yeast! Supposed to be great stuff, I've only used dried yeast so far. Or Wyeast Scottish Ale 1728. Of the dried yeasts I've used, maybe SO4 would work best. Yeast is a major factor though.
