Why do all-grain when you can do BIAB?

Well BIAB is all grain brewing. Not to be confused with just steeping specialty grains in extract brewing. If you have a kettle big enough to do a full mash, doing a partial mash and extract is ...

Is it possible for flavors from the malts to stick with a mash bag?

In practice a nylon bag can become discoloured but it rarely gets so contaminated as to actually affect the flavour of a brew. As long as the bag is cleaned of all debris and thoroughly rinsed it ...

Why do all-grain when you can do BIAB?

BIAB IS all grain brewing. But it's not traditional multi-vessel brewing. Some batch sparge with a cooler, others fly sparge with a sprinkler, some use a bag for the whole water amount (BIAB). All-...

I do normal all grain procedure and the situation is the same. The biggest heat flux will be on outer diemeter of the mash tun. The better the insulation, the smaller the heat flux will be. Usually ...

Is it possible for flavors from the malts to stick with a mash bag?

I've not experienced any carry over from stained bags or beer lines for that matter. If it's clean, it's clean. Staining is usually just a pigment change. I guess it's about like tasting a washed ...

How do you wash nylon grain bags for first use?

No soap. Don't weaken them in the sun. Just drop in PBW for at least 1/2hr. Rinse in hot water (at least as hot as the water was when you started soaking it). Drip dry

Doing BIAB with several smaller bags instead of a big one

I have been using this method for three years or more, starting off with four bags and then cutting back to three, with between 1.5kg and 2kg per bag. If mixing grain, I split the different varieties ...

Doing BIAB with several smaller bags instead of a big one

In theory this would work. The only caution would be to make sure your milled grain very well blended to have even portions of each grain in each bag. Since mixing it as a whole as once in the mash ...

Doing BIAB with several smaller bags instead of a big one

A brewster friend had just such a set up for all-grain brewing. It seemed to work well and the beer was fine. It seemed easier to handle the smaller bags as they were not as heavy (or so full of wort)....

Are protein rests worthwhile in BIAB?

I do BIAB, and I don't think protein rest has much with extraction efficiency. Mashout temperature has, however: if wort has lower viscosity due to higher temperature, it will better flow from the ...

Should you put entire grain bill through Protein Rest?

I tried wheat and rye only twice. First time I put all my grain thorough beta-glucan and protein rests. There was little to no foam. Second time, I did it only on unmalted grain, malted rye and malted ...

Pre-boil volume when doing a separate boil-down

When I do a boil down, I add water at the end if needed. But I care more about boiling to gravity than volume. Keep in mind that your gravity will not change due to the boil down. You're boilng off ...

Would this grain bill make an Amber Ale?

I figure approximately 20-22 SRM. You might be pushing the color a bit towards the darker end, but it will work I think. Maybe go to 7oz each of the C60 and the Amber.

Unadjusted readings from refractometers are accurate only with no alcohol present in the sample. So taking a reading on fermented beer will not give you an accurate specific gravity. Also, as an ...

TL;DR There might be difference in final beer quality, but: The difference will be SMALL (and who knows, BIAB might actually give you a better result). You can mitigate any negative effects with ...

BIAB, Can I use lees water for mashing and then top it for cooling?

Yes, it will work and I believe that doing so is a common trend among BIAB brewers. What you're describing is pretty similar to extract brewing (except you're sort of making your own extract) so there ...
