Frequently Asked Questions

Because a printed price goes stale within days, and a stale number is a claim we cannot support. This site shows a price only when it comes from a live, dated feed, and when it does the date it was checked appears alongside it. Otherwise the button reads Check price on Amazon and you see the retailer's current price when you arrive.

Not all of it, and we say so on every page where that matters. We do not run a test lab. Our recommendations rest on published manufacturer specifications, current retail availability, documented homebrewer consensus, published brewing experiments, and the owner's hands-on use where it exists. Where a verdict rests on specs and consensus rather than first-hand use, the page states that in those words.

Because no such data exists for this site. We have not collected user reviews and we are not going to generate numbers to fill a layout. That also means we deliberately do not emit Review, AggregateRating or Offer structured data, since all three would assert data we do not have.

Affiliate links, currently Amazon Associates only. We earn a commission on qualifying purchases at no extra cost to you. Commission rate never affects ranking, there are no paid placements or sponsored posts, and several pages here recommend not buying the category at all until something cheaper is sorted first.

One person: Brijon M., the hands-on owner behind MadGrey LLC. Every page carries that byline. There is no rotating roster of freelancers and no editorial team standing in for one person.

No. We are a publisher with no premises, no warehouse and no stock. If you buy something through a link here, the retailer handles the order, shipping, returns and warranty. We cannot help with any of those, and we genuinely do not know what something costs today.

Fermentation temperature control -- a dual-stage controller and any used fridge or freezer. It is the cheapest meaningful upgrade available and the only one that changes how your beer tastes rather than how consistently you make it, because fermentation temperature governs the flavor compounds yeast produces.

Almost always fermentation temperature. Yeast produces fruity esters and harsh solvent-like fusel alcohols when it ferments too warm, and active fermentation generates enough heat that a 72 degree room ferments beer at closer to 78. That is the flavor people recognize, and it is a temperature problem rather than a skill problem.

It gives you more control and costs less per batch, but it does not automatically make better beer. Malt extract is produced by commercial maltsters with tighter process control than any homebrewer has. The faults people blame on extract usually trace to stale extract or a partial boil rather than the method itself.

Ten gallons for a 5 gallon batch, fifteen for a 10 gallon batch. Pre-boil volume for a 5 gallon batch is around 7 gallons, hot break foams substantially in the first minutes, and the margin between a vigorous boil and a boilover is only a few inches of freeboard.

It is worth it if you harvest yeast, want to dump trub mid-fermentation, or want closed transfer from a pressure-rated model. It is not worth it purely for beer quality: a bucket held at a steady 66 degrees Fahrenheit produces better beer than a stainless conical in a 76 degree garage.

Fermenting in a sealed rated vessel at 10 to 15 psi, where dissolved CO2 suppresses ester and fusel production so you can ferment clean at warmer, faster temperatures. The bigger reason to buy a rated vessel is closed transfer: pushing beer to a purged keg under CO2 so it never meets air, which is the largest single quality gain available on hoppy beer.

A keezer holds more kegs per dollar, insulates better and pours a colder first glass, at the cost of a weekend with a saw. A kegerator works the day it arrives, is warrantied and looks deliberate in a living space. Location usually decides it: garage means keezer, kitchen means kegerator.

Almost certainly not. A chest freezer with a dual-stage controller holds a setpoint within a degree for a fraction of the purchase and running cost. Glycol earns its place when your fermenter is too tall for any chamber you can fit, when you run several vessels at different temperatures, or when you crash cool every batch and want it fast.

The BrewZilla Gen 4.1 is the best value for most brewers because the pump, chiller and wifi are included. The Anvil Foundry 10.5 is the right choice if your electrical supply might change, since it is the only one that switches between 120V and 240V. The Grainfather G40 wins on automation and support at a clear premium.

Because the changes are functional rather than cosmetic and the market does not label them clearly. BrewZilla Gen 3, Gen 4 and Gen 4.1 have different pumps and bases; the Anvil Foundry 6.5 and 10.5 differ in batch-size ceiling rather than just capacity. A review that does not state its revision may describe hardware two versions old.

It is one of the best value purchases in the hobby. Setting your own crush gap commonly gains several points of mash efficiency over a shop's one-size-fits-all crush, and milling on brew day preserves aroma that dissipates within days of crushing. Buying whole grain in sacks also lowers ingredient cost permanently.

Every two weeks of active service, and always between kegs of very different beers. Lines develop a biofilm of lactic and acetic acid bacteria that sours everything passing through while the beer in the keg stays fine, which is why brewers usually blame the batch. A full cycle takes about twenty minutes.

Most of it. Hydrometers, auto-siphons, airlocks, bungs, tubing, sanitizer and a temperature-controlled chamber all transfer unchanged, which makes mead the cheapest second hobby available to a beer brewer. The exception is long aging: use glass or stainless rather than PET for anything sitting more than a couple of months.

Only if it was under-nourished. Honey lacks the nitrogen yeast needs, and a mead fermented without a staggered nutrient schedule throws fusel alcohols that genuinely do need a year to mellow. Fed properly, the same mead is pleasant at two months and good at six.

Two to three pounds per gallon. Three pounds per gallon gives a starting gravity around 1.100, which with a robust wine yeast ferments to roughly 13 percent alcohol. That means a five gallon batch needs 12 to 15 pounds, which is why starting at one gallon is sensible rather than timid.

The tier, not the grape on the label. Higher tiers contain more actual juice and less concentrate, and that difference shows up directly as body and length. A high-tier chardonnay beats a low-tier amarone, so pick the tier first and the varietal second.
