BatchBlendr calculates the exact specific gravity, ABV, and final volume when you combine two batches of mead. Enter your numbers. Get the blend.
Fill in both batches — mix units freely — then calculate.
"The gravity math I'd been doing on a napkin,
finally somewhere it can't smear."

Meadmakers blend for a reason: two separate fermentations often arrive at separate places. One runs dry because the yeast was hungry. One holds sweetness because you pulled it early. Neither is a mistake — they're raw material.
BatchBlendr treats the blend as the final fermentation step, the one you control completely. No yeast opinion, no temperature variance — just arithmetic applied to the honey you worked hard to ferment.
We built this because the calculations aren't hard, but doing them wrong wastes a season. Get it right the first time.
Step 01
Record the specific gravity (SG), ABV, and volume for each batch you want to combine. Use your hydrometer reading — no conversion needed.
→ SG range: 0.990–1.200
Step 02
Plug each batch into BatchBlendr. Mix units freely — gallons and liters work side by side. We handle the conversion.
→ Gallons · Liters · Mixed
Step 03
Hit Calculate. BatchBlendr returns the weighted average SG, ABV, and total volume — plus a sweetness descriptor so you know what you're building.
→ Bone Dry → Dessert
Weighted SG
Volumetrically correct gravity calculation — not a simple average. Your hydrometer won't be surprised.
Blended ABV
Alcohol by volume scales with the actual liquid present, not the batch count. No off-by-a-point mistakes.
Sweetness descriptor
Bone Dry through Dessert — BatchBlendr interprets the SG result so you know what you're bottling before you blend.
Volume ratio bar
Visual breakdown of how much each batch contributes to the final volume. Useful when one batch is precious.
Mixed unit support
Batch one in gallons, batch two in liters? Fine. We convert before the math so the result is always consistent.

“I used to blend by taste and hope. Now I blend by target. The difference is about 40 gravity points of confidence.”

“Saved a cyser that came out too alcoholic by blending in a sweeter half-batch. BatchBlendr told me exactly how much to pour.”

“The sweetness label is genuinely useful. Knowing I'm landing in 'Semi-Sweet' territory before I commit the glass is worth the two minutes it takes.”

The Mead Log
Blending is one of the most powerful tools a meadmaker has — but only if you understand the math behind it. Learn how to calculate the perfect blend ratio to hit your target ABV, sweetness, and flavor profile without guesswork. We walk through the exact process BatchBlendr automates so you can fix problem batches and craft intentional blends.
Not every mead ferments perfectly — and dumping a flawed batch is almost never the right answer. From overly dry meads to hot alcohol notes and thin body, blending is a surprisingly effective fix for at least 10 recurring homebrew headaches. Discover which problems respond best to blending and how to calculate the ratios that restore balance.
Blending across mead styles — traditional, melomel, cyser, metheglin — can produce complex, layered results that no single batch achieves alone. But not all combinations work: some clash on tannins, acidity, or residual sugar. This guide maps out the most successful cross-style blending pairings and the flavor science behind why they work.
Most homebrewers eyeball their blends — and most of the time, they regret it. A mead blending calculator takes the guesswork out of hitting your target ABV, gravity, and volume by running the math before you open a single bottle. This ultimate guide explains exactly how blending calculators work, what inputs they need, and how tools like BatchBlendr save you time, honey, and heartbreak.
Some of the most celebrated meads in homebrew competition history weren't planned — they were the result of a bold (or accidental) blend between two batches. We profile five competition-winning recipes where blending was the secret weapon, breaking down the ratios, honey varietals, and adjuncts that made each one stand out. Let their stories inspire your next batch.
