Re: Reversing the Flow through the Malt Pipe on 20lt BM

Hey wobbly, I like the BM concept of "reverse flow" circulation. It fundamentally separates the BM from the others which recirculate from the top down, so it comes down to whichever school you go with. I got a BM because I like the way it does things. To try to re-engineer a BM to act like a Grainfa...

Re: need to replace mesh filter

I'm thinking of getting a pair or two of these, but the mesh size?

On their website, Inoxia recommends a 30 mesh, however the size being ordered here seems to be 20 mesh (same as original Speidels). Have any of you guys used the 30 mesh?

Re: BM50 LOB setup

With 12.2 kg of grain and a brew length of 47 litres (44 in the fv) the OG in my system would be 1.066. That is significantly higher than 1.051. My efficiency is 83%. Follow my advice about mashing and you will achieve the same. Hi IPA Second brew just finished. With attention to good stirring of t...

Re: BM50 LOB setup

I'll steer clear of the underletting. It complicated things big time. With my HERMS system, I set the efficiency at 81% and I was bang on with my numbers, so I'd expect at least as good in the BM. (doughing in the same way, bit by bit and stirring all the way) Incidentally, I'm using Beersmith 2, an...

Re: BM50 LOB setup

Hey mashy and IPA, I certainly respect that you guys have made nice beers, as have I (mostly ales), but I've never actually tasted a fresh commercial beer (as in lighter German styles) brewed using LODO techniques, so I have nothing to compare with. You guys over in Europe are probably spoiled for c...

Re: Rubber Seal for filter plates

I thought the U profile might be more resistant to rolling off. I'll check out their range to see whether another profile might be more suitable.

Thanks for the tip on creasing though.

Re: BM50 LOB setup

Yeah, I understand where you're coming from. I'm generally a follower of the KISS principle, but something about LOB intrigues me, so I'll give it a go, taste, compare, and see whether it's worthwhile for me. Incidentally, I have in the last hour, ordered Graham Wheeler's book "Brew Classic European...

Re: Rubber Seal for filter plates

How do you guys think this silicone profile would go for a seal around the top plate inside the malt pipe?

Re: BM50 LOB setup

The two methods for removing dissolved oxygen (DO) in the strike water are: (a) boil it vigorously for five minutes, then chill it down to strike temperature; and/or (b) set up a mini fermentation, by dosing it with dried baker's yeast and dextrose (at ambient temperature). Leave it for 2 to 3 hours...

Re: BM50 LOB setup

Yeah, the mash was really thick -- like very difficult to even stir it to any extent -- and when I cleaned out the mashpipe I noticed a lot of doughballs. My next mission is to fabricate an efficient mash stirrer to thoroughly mix the grain without adding too much oxygenation. So, early days, and on...

BM50 LOB setup

Well, it's all come together. The new hood and LOB kit arrived, my sparky installed a 15amp power socket in the brew shed, and Saturday, my first ever brew with my "new" 2nd hand BM. I used the baker's yeast/dextrose treatment to prepare the strike water, filled to the top mark (55 litres) then slow...

Re: Hi from SE Qld (Australia)

Hey Mashy, here in Oz they're sold as Giantz, but yeah - they've made their way all over, just under different brand names. Cost here is as low as AU$80 delivered!

Re: Hi from SE Qld (Australia)

Thanks Wally - nice setup. I have the same electric winch as yours, and brew in an enclosed shed which has a mezzanine floor extending over half the ground floor, so I've hung the hoist over the edge of the mezzanine floor (fixed position), and have the BM on my old 3v mobile trolley. Pics of the fu...

Re: Sous Vide in the BM

I'm looking for recommendations for a good basic book on Sous Vide cooking. My wife presented me with an absolute cracker of a book at Christmas - "Under Pressure" (Thomas Keller), but it is VERY high end, and what I need is a more basic 101 starter. I have an over-the-side sous vide stick, but now ...
