So, I did my first all-grain brew day yesterday and now that it's done, I had a few questions...
First, my setup:
10 Gal coolers (MLT and HLT)
SS False bottom on the MLT
I did a batch sparge split into 2 sparges on a Northern Brewer Saison kit with about 10.75 lbs of grain. About 5 gallons of mash water, 2.75 gallons sparge water, total.
Issue #1: Vorlauf not clearing
- I ran the first runnings into a pitcher (about 1.5 gallons) a quart at a time, slow drain, fast drain, etc and I kept getting significant debris. I feel the false bottom was not fine enough to catch a lot of this, but I'm not sure. Also wondering if starting and stopping so often (one quart at a time) could cause it? Either way, I put a fine mesh bag over the drain tube and ran it wide open. Used it in the sparge as well. Seems to work fine (no pun intended ), any drawbacks to this?
Issue #2: Low Sparge temps
- My grains seemed to suck more heat than I expected, and my sparge was only about 155 to 160 (Target of 170-175), using roughly 185 strike/sparge water. How will this end up affecting the beer? I may be wrong on that large of an inconsistency, my thermometers all seem to read differently, and not consistently. My notes are also at home.
On my sparge, I also added 1.5 gallons on the second sparge, and only used 1.25 (thought it would be enough, pre-boil). Does this effect things much; not using all the sparge?
Target OG (per recipe) was 1.056 and I hit 1.05 pre boil, 1.06 post boil, right at 5 gallons. I would have rather ended up with 5.5 gallons, but I ended up boiling off more than a normal extract batch. Decided not to bother adding any extra water.
Items I know I need to change:
- Foil on top of the grain bed to hold heat and better distribute vorlauf without channeling (if I do a vorlauf again)
- Try warmer sparge water and triple check temps to see if it is working or not
- Shoot for higher pre-boil volume
Any other tips/input? I'm happy that I hit my target OG (overshot actually) on my first batch. How do I check efficiency, brewhouse and overall? Software? I haven't gotten anything yet, but plan on something soon.
