What is a dry hop rate in g/L?

A dry hop rate expresses how much hop material you add per litre of beer. Multiplying the rate by the batch volume gives the total weight. For example, 8 g/L in a 20-litre batch needs 160 grams of hops.

What are typical dry hop rates?

A balanced pale ale is around 2 to 4 g/L, a West Coast IPA around 4 to 8 g/L, and a hazy NEIPA often 8 to 16 g/L or more. Lagers use very light rates of about 0.5 to 2 g/L. Higher rates increase aroma but also hop creep and beer loss to absorption.

How much beer do hops absorb?

Loose hop material soaks up roughly its own weight in beer, about 1 to 2 millilitres per gram. At very high NEIPA rates this can cost a litre or more of finished beer, so account for it when planning packaging volume.

Should I split the dry hop into multiple additions?

Many brewers split a large charge into two: one during active fermentation for biotransformation and one after for fresh aroma. The total weight is the same; this calculator gives that total, which you then divide between charges.

Does dry hopping add bitterness?

Dry hopping adds aroma and a perceived hoppy character but very little measured IBU, because no isomerisation happens without heat. It can, however, cause hop creep, where leftover enzymes restart fermentation and dry the beer out further.

Dry Hop Rate Calculator

This calculator converts between a dry hop rate in grams per litre and the total hop weight for your batch — the everyday arithmetic of hop-forward brewing. Enter your volume and rate, or load a typical rate for your beer style from the built-in table.

How it works

A dry hop rate is just a density of hops per unit of beer:

total hop weight (g) = rate (g/L) × batch volume (L)

The calculator also reports the equivalent per-gallon figure for recipes written in US units:

rate (g/gal) = rate (g/L) × 3.78541

You can work the formula in either direction: enter a target rate to get the weight, or the tool will show you the effective rate if you already have a fixed amount of hops to use up.

Style reference table

Style	Typical dry hop rate
Lager / Pilsner	0.5 – 2 g/L
Pale Ale	2 – 4 g/L
West Coast IPA	4 – 8 g/L
Double IPA	6 – 12 g/L
Hazy / NEIPA	8 – 16 g/L
Triple / Imperial Hazy	12 – 20 g/L

Worked example

For a hazy NEIPA at 10 g/L in a 19-litre (5 US gallon) batch:

total = 10 g/L × 19 L = 190 g (about 6.7 oz)

If you split that across two charges, that is 95g during fermentation and 95g after. Expect to lose roughly 190ml to 380ml of beer to hop absorption at this rate, so brew a little long if you need a full keg.

Tips and notes

Whirlpool and dry hop are different: this tool covers cold-side dry hopping only, which contributes aroma, not measured IBU.
Pellets pack and absorb less beer than whole-leaf hops; at very high rates pellets are strongly preferred to limit losses.
Higher rates increase hop creep risk — residual enzymes can restart fermentation, raising ABV and drying the beer. Monitor gravity before packaging.
Always dry hop the volume actually in the fermenter; using the boil volume overestimates the charge.
