its just a perferated plate that i guess is supposed to even out how the water is spread over the grain bed like a shower head..  i find it just slowly slips down and compresses the grain bed.. creating slower filtration and sparge..  plus if you get a mash with dust that settles on top it can create like a mud layer that blocks the grain bed..   if you have the plate there you cant get in with your paddle to mix up the top inch of the bed to fix the flow

i used it on the sparge yesterday but even then its pretty much useless as i dont allow the malt pipe to become empty during sparge to control the ph levels of the water ect.. i try to avoid putting just plain water through the grain after all the problems i had with strange flavours.. so i try and keep a mix of wort and water so its a batch sparge i guess

I have seen you tube vids' where they don't use the top plate for the same reasons you have mentioned Geoff, like if you want to have a stir for a stuck sparge. So far I haven't had any problems but on one occasion when the sparge was a bit slow due to the grind being a bit fine, in that case it would have been useful to have not had it on. Whatever works for the the person brewing is what must be done I guess. That colour looks real nice.

i wouldn't say it was really causing me lots of problems that would ruin the brew day..   but its certainly seemed to work better without it for me,  plus its one less thing to have to clean..  😂

i dunno i may change my mind next brew .. who knows, but like you say we all seem to find our own way in this hobby..  strange really considering there's so many rules

True.......Brewing is like art, we all paint different pictures according to our tastes................Woops, that sounds a bit philosophical I had better watch myself.....😄

this is a style i have fancied making for a while.. not sure how accurate i have been to the style as i have tried to be a bit less in the abv stakes..  i also thought this would be a good beer to try the riwacka, and I've mixed it with some galaxy, Amarillo and comet..

i had some Amarillo and galaxy left over from previous brews and the comet was a 25g pack i won in the cml comp, i have never used the comet before but it smelt very nice..  the pack was pretty much all hop dust

as this was my first time brewing with oats i was not sure what kind of efficiency i would get or how the robobrew would deal with it, so i played safe and planned the recipe at around 75%

i did not use the sparge plate again and it was a good decision as the mash needed a little bit of encouragement at times so not having the plate there allowed me to get in and give it a stir to keep the flow smooth, i now understand what folks mean by a sticky mash..

final brewday efficiency was 80% so it should of sent off my target numbers but fortunately i had over sparged so ended up just 1 point over but with 22-23 litres of wort..  this is the 2nd brew without the sparge plate and both times I've been at 80% so i think ill adjust my brewing software to 80% and chuck the sparge plate in a box.

i used the cml voss Kviek again for this one..  thought its citrus flavours can only add to this style of beer, i took it from the fridge first thing this morning to let it warm up too room temp and you could see it starting to come alive in the jar after an hour or so..  drained off the beer and added a small amount of cooled boiled water, gave it a good shake and put half of the yeast in a smaller mason jar..

i added 3 grams of murphys yeast vit to the remaining Slurry and topped the jar up with some of the wort from the boiler as i was filling the fermenter

and just pitched it in..   huge over-pitch by all accounts but i couldn't be arsed to mess about

this time with the added yeast nutrient there was no delay to the yeast getting going like i had with the 2 previous kviek brews, its behaved exactly the same as when i pitched it dry the first time..   life in the fermenter after 30 mins and now going like the clappers..  expect it to be done very quickly

all in all a great brewday..

well this was coming to the end of fermention yesterday after 24 hours.. the ispindle ive used i know is around 3 - 4 points out so i think the gravity would of been around 1.011 plus maybe a bit for temp correction

so i dry hopped it while there was still a bit of co2 being released, seems a bit bonkers to be at this stage already..  ill keg it at the weekend i guess,  itl certainly be very fresh beer

the dry hop played havoc with the ispindel but its slowly coming right as the hops are dropping in the fermenter,  fermention is pretty much done now with only the odd blip in the blow off bottle..

this could be ready to send to @Stiggy in the comp..   who knows!

Glad the kviek kicked off like it's supposed to. Crazy to think a 1.054 OG beer requires added nutrients. 😆
